The earliest well-documented case of HIV in a human dates back to 1959 in the Congo.[243] The earliest retrospectively described case of AIDS is believed to have been in Norway beginning in 1966.[244] In July 1960, in the wake its independence, the United Nations recruited Francophone experts and technicians from all over the world to assist in filling administrative gaps left by Belgium, who did not leave behind an African elite to run the country. By 1962, Haitians made up the second largest group of well-educated experts (out of the 48 national groups recruited), that totaled around 4500 in the country.[245][246] Dr. Jacques Pépin, a Quebecer author of The Origins of AIDS, stipulates that Haiti was one of HIV’s entry points to the United States and that one of them may have carried HIV back across the Atlantic in the 1960s.[246] Although the virus may have been present in the United States as early as 1966,[247] the vast majority of infections occurring outside sub-Saharan Africa (including the U.S.) can be traced back to a single unknown individual who became infected with HIV in Haiti and then brought the infection to the United States some time around 1969.[248] The epidemic then rapidly spread among high-risk groups (initially, sexually promiscuous men who have sex with men). By 1978, the prevalence of HIV-1 among homosexual male residents of New York City and San Francisco was estimated at 5%, suggesting that several thousand individuals in the country had been infected.[248]

Without treatment, human immunodeficiency virus (HIV) infection will usually result in acquired immune deficiency syndrome (AIDS). However, in Australia the HIV therapies introduced in the mid-1990s, which are available to all Australians living with HIV, have resulted in fewer AIDS related illnesses and deaths. Therefore, whilst a cure is yet to be found for HIV and it remains a lifelong infection, HIV in Australia is now considered a chronic manageable condition.

Antiviral medications are associated with adverse effects and thus contribute to patient morbidity and mortality rates, especially because of the growing population of long-term survivors who are receiving combination antiviral therapy. In particular, protease inhibitors may cause lipid-profile abnormalities.

AIDS-related symptoms also includes serious weight loss, brain tumors, and other health problems. Without treatment, these opportunistic infections can kill you. The official (technical) CDC definition of AIDS is available at http://www.thebody.com/content/art14002.html

HIV testing should be voluntary and the right to decline testing should be recognized. Mandatory or coerced testing by a health care provider, authority, or by a partner or family member is not acceptable as it undermines good public health practice and infringes on human rights.

People who already have a sexually transmitted infection, such as syphilis, genital herpes, chlamydia, human papillomavirus (HPV), gonorrhea, or bacterial vaginosis, are more likely to acquire HIV infection during sex with an infected partner.

The Sixty-ninth World Health Assembly endorsed a new Global Health Sector Strategy on HIV for 2016-2021. The strategy includes 5 strategic directions that guide priority actions by countries and by WHO over the next six years.

Transmission of HIV requires contact with body fluids—specifically blood, semen, vaginal secretions, breast milk, saliva, or exudates from wounds or skin and mucosal lesions—that contain free HIV virions or infected cells. Transmission is more likely with the high levels of virions that are typical during primary infection, even when such infections are asymptomatic. Transmission by saliva or droplets produced by coughing or sneezing, although conceivable, is extremely unlikely.

A course of antiretrovirals administered within 48 to 72 hours after exposure to HIV-positive blood or genital secretions is referred to as post-exposure prophylaxis (PEP).[136] The use of the single agent zidovudine reduces the risk of a HIV infection five-fold following a needle-stick injury.[136] As of 2013, the prevention regimen recommended in the United States consists of three medications—tenofovir, emtricitabine and raltegravir—as this may reduce the risk further.[137]

Because of the inaccurate results, the FDA has not approved any of the home-use HIV tests which allow people to interpret their tests in a few minutes at home. There is however a Home Access test approved which can be found at most drugstores. In this test blood from a finger prick is placed on a card and sent to a licensed lab. Consumers are given an identification number to use when phoning for results and have the opportunity to speak with a counselor if desired.

AIDS (acquired immunodeficiency syndrome) is a syndrome caused by a virus called HIV (human immunodeficiency virus). The disease alters the immune system, making people much more vulnerable to infections and diseases. This susceptibility worsens if the syndrome progresses.

HIV is transmitted by three main routes: sexual contact, significant exposure to infected body fluids or tissues, and from mother to child during pregnancy, delivery, or breastfeeding (known as vertical transmission).[12] There is no risk of acquiring HIV if exposed to feces, nasal secretions, saliva, sputum, sweat, tears, urine, or vomit unless these are contaminated with blood.[49] It is possible to be co-infected by more than one strain of HIV—a condition known as HIV superinfection.[50]

During late-stage HIV infection, the risk of developing a life-threatening illness is much greater. Serious conditions may be controlled, avoided, and/or treated with other medications, alongside HIV treatment.

Stevens-Johnson syndrome (SJS) is a rare allergic reaction to HIV medication. Symptoms include fever and swelling of the face and tongue. Rash, which can involve the skin and mucous membranes, appears and spreads quickly.

The diagnosis for malaria is conducted by analyzing blood for malarial parasites. Prescription drugs can be used to cure individuals of malaria depending on the type of malarial infection, severity of infection, and other factors.

ART may have a variety of side effects depending on the type of drug. An expert in infectious diseases and HIV treatment should be consulted if the patient needs concomitant treatment for opportunistic infections, hepatitis B, or hepatitis C. Some medications used to treat these conditions will negatively interact with ART drugs.

Early advances in preventing HIV transmission resulted from educational programs describing how transmission occurs and providing barrier protection for those exposed to genital secretions and new needles or bleach to those exposed to blood by sharing needles. Despite these efforts, new infection in both the developed and developing worlds has continued at high rates.

Treatment with antiretroviral drugs is recommended for almost all people with HIV infection because without treatment, HIV infection can lead to serious complications and because newer, less toxic drugs have been developed. For most people, early treatment has the best results.

Importantly, many researchers have consistently shown that the primary risk factor for infection affects mortality. For example, the mortality rate among intravenous drug users tends to be higher, whether related to HIV disease or non-HIV disease.

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV).[9][10][11] Following initial infection, a person may not notice any symptoms or may experience a brief period of influenza-like illness.[5] Typically, this is followed by a prolonged period with no symptoms.[6] As the infection progresses, it interferes more with the immune system, increasing the risk of common infections like tuberculosis, as well as other infections, and tumors that rarely affect people who have working immune systems.[5] These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS).[6] This stage is often also associated with weight loss.[6]

The total number of cases of HIV in the UK includes 120 cases from injecting drug use (IDU). IDU has played a smaller part in the HIV epidemic in the UK than it has in many other European countries and the numbers of new diagnoses have been around 100 for the last few years. In 2013, the prevalence in England, Wales and Northern Ireland in recent initiates to injectable drugs was 1.0%. This was similar to previous years, suggesting that this source of infection remained at relatively low levels.[10]

Kaposi’s sarcoma. A tumor of the blood vessel walls, this cancer is rare in people not infected with HIV, but common in HIV-positive people. It usually appears as pink, red or purple lesions on the skin and mouth. In people with darker skin, the lesions may look dark brown or black. Kaposi’s sarcoma can also affect the internal organs, including the digestive tract and lungs. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]

The second role of the federal government is largely symbolic but no less controversial. It is to guide school efforts through advice, sponsorship, and public speeches, and primarily involves the offices of the surgeon general and of the federal AIDS policy coordinator. Koop, who was a Reagan appointee, roused a fair degree of controversy, yet it was nothing compared to the upheaval that greeted statements by appointees of the Clinton administration. AIDS policy czar Kristine Gebbie and surgeon general M. Joycelyn Elders were forced from their posts after making statements that conservatives found appalling—Gebbie promoting attitudes toward pleasurable sex and Elders indicating a willingness to have schools talk about masturbation. Thereafter, the administration frequently stressed abstinence as its top priority for school AIDS programs.

Confidentiality relating to HIV is not uniform in schools. Some school districts require rather broad dissemination of the information; others keep it strictly private. In the mid-1980s, the New York City Board of Education adopted a policy that nobody in any school would be told the identities of children with AIDS or HIV infection; only a few top administrators outside the school would be informed. The policy inspired a lawsuit brought by a local school district, which argued that the identity of a child was necessary for infection control (District 27 Community School Board v. Board of Education, 130 Misc. 2d 398, 502 N.Y.S.2d 325 [N.Y. Sup. Ct. 1986]). The trial court rejected the argument on the basis that numerous children with HIV infection might be attending school and instead noted that universal precautions in dealing with blood incidents at school would be more effective than the revelation of confidential information.

Additional precautions – people living with AIDS should be extra cautious to prevent exposure to infection. They should be careful around animals and avoid coming into contact with cat litter, animal feces, and birds, too. Meticulous and regular washing of hands is recommended. These precautions are not as necessary while taking therapy.

Production of the clotting factor concentrates, mainly to treat patients with haemophilia A and haemophilia B (Christmas disease), involves the pooling of very many donations and a single donation could contaminate a batch of concentrate used to treat many patients. There have been no recorded transmissions of HIV by this route in the UK since the introduction of heat inactivation of concentrates and donor screening in 1985.

How would it make u feel, if someone u knew had aids? Would u feel sad or sorry for them or treat them as the living breatheing human that they are, with or without tne diease. Would you stop to think how scared they were or just judge them? People assume there is only one way to get aids and that is by being gay. Our world is VERY NARROW MINDED. Imagine how u would feel, and how u wouldn’t want someone to stop loving you as a PERSON, just because u contracted it. Hospital needles not properly disposed of, that one may get pricked with. If u have to have a transfusion. Passing it thru sex, comes when u didn’t realize u had contracted it some how. I know someone, whom I dearly love with this hidden demon, I see his sadness and feel his pain, “for if anyone knew…… they would change how they really looked at him. We all are going to die, each of us in different ways….. so we should live, love and not stereo type while we are alive. I have learned alot just by knowing this person and u know what? I enjoy every minute and every conversation, every laugh and smile, because i know it makes a difference in their world too! Get educated and open ur mind and ur heart to everyone.

The virus that causes AIDS, which is the most advanced stage of HIV infection. HIV is a retrovirus that occurs as two types: HIV-1 and HIV-2. Both types are transmitted through direct contact with HIV-infected body fluids, such as blood, semen, and genital secretions, or from an HIV-infected mother to her child during pregnancy, birth, or breastfeeding (through breast milk).

HIV is one of a group of viruses known as retroviruses. After getting into the body, the virus enters many different cells, incorporates its genes into the human DNA, and hijacks the cell to produce HIV virus. Most importantly, HIV attacks cells of the body’s immune system called CD4 or T-helper cells (T cells). These cells are destroyed by the infection. The body tries to keep up by making new T cells or trying to contain the virus, but eventually the HIV wins out and progressively destroys the body’s ability to fight infections and certain cancers. The virus structure has been studied extensively, and this ongoing research has helped scientists develop new treatments for HIV/AIDS. Although all HIV viruses are similar, small variations or mutations in the genetic material of the virus create drug-resistant viruses. Larger variations in the viral genes are found in different viral subtypes. Currently, HIV-1 is the predominant subtype that causes HIV/AIDS. HIV-2, another form of HIV, occurs almost exclusively in West Africa.

Doctors will use a wide variety of tests to diagnose the presence of opportunistic infections, cancers, or other disease conditions in AIDS patients. Tissue biopsies, samples of cerebrospinal fluid, and sophisticated imaging techniques, such as magnetic resonance imaging (MRI) and computed tomography scans (CT) are used to diagnose AIDS-related cancers, some opportunistic infections, damage to the central nervous system, and wasting of the muscles. Urine and stool samples are used to diagnose infections caused by parasites. AIDS patients are also given blood tests for syphilis and other sexually transmitted diseases.

HIV antibody tests detect antibodies the body produces to neutralize the virus. HIV RNA testing uses polymerase chain reaction to detect HIV RNA in a person’s blood. It usually takes one to three days to get results.

During a blood transfusion, blood or blood products are transferred from one person to another. There are two types of transfusions, autologous (your own blood), and donor blood (someone else’s blood). There are four blood types: A; B; C; and O.

Sturdevant, born and raised in Metcalfe, a tiny Mississippi Delta town of about 1,000, understands all too well the fear, stigma and isolation that can come with being a black gay man in the South. “Growing up, I was taught that God was not fixing to forgive a person who was homosexual,” Sturdevant said. “The Bible supposedly said you’re going straight to hell, automatically, there’s no forgiveness. There were several times I thought about suicide. There were several times I wanted to get sick and die. Finally, my thought was, I just want to get out of here.” He moved to Dallas, and then to Memphis.

Transition to these new ARV options has already started in more 20 countries and is expected to improve the durability of the treatment and the quality of care of people living with HIV. Despite improvements, limited options remain for infants and young children. For this reason, WHO and partners are coordinating efforts to enable a faster and more effective development and introduction of age-appropriate pediatric formulations of antiretrovirals.

Once the virus has infected a T cell, HIV copies its RNA into a double-stranded DNA copy by means of the viral enzyme reverse transcriptase; that process is called reverse transcription, because it violates the usual way in which genetic information is transcribed. Because reverse transcriptase lacks the “proofreading” function that most DNA-synthesizing enzymes have, many mutations arise as the virus replicates, further hindering the ability of the immune system to combat the virus. Those mutations allow the virus to evolve very rapidly, approximately one million times faster than the human genome evolves. That rapid evolution allows the virus to escape from antiviral immune responses and antiretroviral drugs. The next step in the virus life cycle is the integration of the viral genome into the host cell DNA. Integration occurs at essentially any accessible site in the host genome and results in the permanent acquisition of viral genes by the host cell. Under appropriate conditions those genes are transcribed into viral RNA molecules. Some viral RNA molecules are incorporated into new virus particles, whereas others are used as messenger RNA for the production of new viral proteins. Viral proteins assemble at the plasma membrane together with the genomic viral RNA to form a virus particle that buds from the surface of the infected cell, taking with it some of the host cell membrane that serves as the viral envelope. Embedded in that envelope are the gp120/gp41 complexes that allow attachment of the helper T cells in the next round of infection. Most infected cells die quickly (in about one day). The number of helper T cells that are lost through direct infection or other mechanisms exceeds the number of new cells produced by the immune system, eventually resulting in a decline in the number of helper T cells. Physicians follow the course of the disease by determining the number of helper T cells (CD4+ cells) in the blood. That measurement, called the CD4 count, provides a good indication of the status of the immune system. Physicians also measure the amount of virus in the bloodstream—i.e., the viral load—which provides an indication of how fast the virus is replicating and destroying helper T cells.

human T-cell lymphotropic virus type III; a cytopathic retrovirus (genus Lentvirus, family Retroviridae) that is 100-120 nm in diameter, has a lipid envelope, and has a characteristic dense cylindric nucleoid containing core proteins and genomic RNA. There are currently two types: HIV-1 infects only humans and chimpanzees and is more virulent than HIV-2, which is more closely related to Simian or monkey viruses. HIV-2 is found primarily in West Africa and is not as widespread as HIV-1. In addition to the usual gene associated with retroviruses, this virus has at least six genes that regulate its replication. It is the etiologic agent of acquired immunodeficiency syndrome (AIDS). Formerly or also known as the lymphadenopathy virus (LAV) or the human T-cell lymphotropic virus type III (HTLV-III). Identified in 1984 by Luc Montagnier and colleagues.

Condomless sex – having sex without a condom can put a person at risk of contracting HIV and other sexually transmitted infections (STIs). HIV can be transmitted by having sex without a condom (vaginal, oral, and/or anal sex). It can also be transmitted by sharing sex toys with someone infected with HIV. Condoms should be used with every sexual act.

Many people do not develop symptoms or signs at all after they are infected with HIV. Others will have signs and symptoms in the first two to four weeks after HIV infection, referred to as primary or acute HIV infection.

In light of the limited ability of counseling and testing to curb the spread of the HIV pandemic, many researchers have moved toward other biologic strategies for preventing HIV that do not rely solely on people changing their behavior. It is in this area where there has been some success. During the last 10 years, there were several large studies showing that male circumcision along with behavioral counseling reduced the risk of heterosexual men acquiring HIV infection. This provides a novel prevention strategy for at-risk, HIV-uninfected heterosexual men. Another major advance on the prevention front came from the HPTN 052 study in which HIV-infected individuals with CD4 cells between 350 cells/mm3 and 550 cells/mm3 who had uninfected partners were randomly assigned to initiate antiviral therapy or wait until their CD4 cells declined to less than 250 cells/mm3 or they developed symptoms consistent with disease progression. All enrolled individuals were aggressively counseled about continued safe sex practices, provided condoms, and were monitored for sexual activities. The study ultimately showed that those treated early were more than 96% less likely to transmit to their partner than those who had antiviral treatment deferred. Subsequent cohort studies have shown that those who are virologically suppressed on antiretroviral therapy for at least six months have a very low risk of transmitting to uninfected partners, even when not using condoms. In fact, many groups have suggested that the risk in this setting of HIV transmission may be virtually zero based upon the existing data.

HIV has been transmitted when organs (kidneys, livers, hearts, pancreases, bone, and skin) from infected donors were unknowingly used as transplants. HIV transmission is unlikely to occur when corneas or certain specially treated tissues (such as bone) are transplanted.

The development of rapid HIV tests is another mechanism to support HIV testing and management. Until recently, HIV testing was performed using the repeatedly reactive enzyme immunoassay followed by confirmatory Western blot or immunofluorescence assay. Although this test is very accurate, the results are not available for 24–48 hours after testing. In contrast, a rapid HIV test is a screening test with results that are available quickly, ideally within an hour. Rapid tests include point-of-care tests performed outside a laboratory (eg, an oral swab testing done in an outpatient setting) as well as testing performed in a laboratory. The tests currently approved by the U.S. Food and Drug Administration range in specificity from 93% to 100% with a sensitivity of 98.6–100% (11). The use of rapid HIV tests may provide test results to patients in a timelier manner and may reduce challenges related to loss to follow-up. Although a positive rapid test result is preliminary and must be confirmed with additional testing, a negative rapid test result does not require any additional testing. Therefore, rapid testing may be a feasible and acceptable approach for an HIV screening program in an obstetric–gynecologic practice (12).

Sexual contact with an infected person, when the mucous membrane lining the mouth, vagina, penis, or rectum is exposed to body fluids such as semen or vaginal fluids that contain HIV, as occurs during unprotected sexual intercourse

Sheen’s third marriage, to actress Brooke Mueller, was also contentious. The two married in 2008 and divorced three years later, time that included Sheen’s arrest on suspicion of domestic abuse and rehab stints for both. A custody battle ensued after the divorce, but the two are getting along for now.

Oral PrEP of HIV is the daily use of ARV drugs by HIV-negative people to block the acquisition of HIV. More than 10 randomized controlled studies have demonstrated the effectiveness of PrEP in reducing HIV transmission among a range of populations including serodiscordant heterosexual couples (where one partner is infected and the other is not), men who have sex with men, transgender women, high-risk heterosexual couples, and people who inject drugs.

Acronym for acquired immune deficiency (or immunodeficiency) syndrome; disorder of the immune system characterized by opportunistic diseases, including candidiasis, Pneumocystis jiroveci pneumonia, oral hairy leukoplakia, herpes zoster, Kaposi sarcoma, toxoplasmosis, isosporiasis, cryptococcosis, non-Hodgkin lymphoma, and tuberculosis. The syndrome is caused by the human immunodeficiency virus (HIV-1, groups M and O, and HIV-2), which is transmitted in body fluids (notably breast milk, blood, and semen) through sexual contact, sharing of contaminated needles (by IV drug abusers), accidental needle sticks, contact with contaminated blood, or transfusion of contaminated blood or blood products. Hallmark of the immunodeficiency is depletion of T4+ or CD4+ helper/inducer lymphocytes, primarily the result of selective tropism of the virus for the lymphocytes.

HIV can be transmitted from mother to child during pregnancy, during delivery, or through breast milk, resulting in the baby also contracting HIV.[76][77] This is the third most common way in which HIV is transmitted globally.[12] In the absence of treatment, the risk of transmission before or during birth is around 20% and in those who also breastfeed 35%.[77] As of 2008, vertical transmission accounted for about 90% of cases of HIV in children.[77] With appropriate treatment the risk of mother-to-child infection can be reduced to about 1%.[77] Preventive treatment involves the mother taking antiretrovirals during pregnancy and delivery, an elective caesarean section, avoiding breastfeeding, and administering antiretroviral drugs to the newborn.[78] Antiretrovirals when taken by either the mother or the infant decrease the risk of transmission in those who do breastfeed.[79] However, many of these measures are not available in the developing world.[78] If blood contaminates food during pre-chewing it may pose a risk of transmission.[74]

Voluntary testing with counseling is the strategy most consistent with respect for patient autonomy. Under this option, physicians provide both pretest and posttest counseling. Some physicians may perform such counseling themselves, whereas others may prefer to refer the patient for counseling and testing. (Such specialized HIV counseling was more widely available in previous years but has become less available as more health care professionals have become more comfortable treating patients with HIV and as the opt-out approach to testing—an approach that places less emphasis on pretest counseling—has become more common.) In addition to medical information, such counseling could include information regarding potential uses of test information and legal requirements pertaining to the release of information. Patients should be told what information will be communicated and to whom and the possible implications of reporting the information. This approach to testing maintains HIV’s status as being in a class by itself (sui generis), even as many ethicists have acknowledged the end to the exceptionalism that marked this disease in the early years of the epidemic (5).

The bias that black gay and bisexual men still face poisons the H.I.V. picture in Mississippi and throughout the South. In 2016, Gov. Phil Bryant of Mississippi signed HB 1523, the Protecting Freedom of Conscience From Government Discrimination Act, one of the country’s most sweeping and repressive anti-L.G.B.T. laws. Though currently blocked by federal court and under appeal, the legislation, if allowed to proceed, would allow churches, religious charities and private businesses to deny services in a broad variety of contexts to L.G.B.T. people.

HIV, or human immunodeficiency virus, attacks the immune system by destroying white blood cells, which are vital to fighting infection. Once enough of these cells have been destroyed and the person has another “opportunistic” infection like pneumonia or tuberculosis, the diagnosis moves to the final stage of the infection, called AIDS.

A poor CD4 count response is more likely if the CD4 count at initiation of treatment is low (especially if < 50/μL) and/or the HIV RNA level is high. However, marked improvement is likely even in patients with advanced immunosuppression. An increased CD4 count correlates with markedly decreased risk of opportunistic infections, other complications, and death. With immune restoration, patients, even those with complications that have no specific treatment (eg, HIV-induced cognitive dysfunction) or that were previously considered untreatable (eg, progressive multifocal leukoencephalopathy), may improve. Outcomes are also improved for patients with cancers (eg, lymphoma, Kaposi sarcoma) and most opportunistic infections. Sex with an infected partner without using a condom or other barrier protection can transmit HIV. The virus can enter the body through the lining of the vagina, vulva, penis, rectum, or mouth during sex. Anal intercourse, followed by vaginal intercourse, are the primary risk factors. Oral sex is less likely to transmit HIV, but studies have shown that it can transmit both HIV and other sexually transmitted diseases (STDs). ^ Jump up to: a b c Herek GM, Capitanio JP (1999).

Some communities have been very hard hit with many deaths and economic hardship related to loss of the workforce of young adults. However, significant progress has been made in the last decade. South Africa has the largest antiviral roll-out programme in the world. Campaigns to reduce homophobia are encouraging MSM to declare their sexuality and come forward for testing and treatment. Innovative work with sex workers and injectable drug users, antiretroviral treatment of children, condom distribution programmes and mother-to-child transmission prevention services are all beginning to bear fruit. Life expectancy has increased by five years since the height of the epidemic.[21]With a prevalence of 17.9% and a population of 6.1 million, South Africa has the largest HIV epidemic of any country. In neighbouring countries in southern Africa, the prevalance ranges from 10-15%.[2] As of 2010, there are 8 known HIV-2 groups (A to H). Of these, only groups A and B are pandemic. Group A is found mainly in West Africa, but has also spread globally to Angola, Mozambique, Brazil, India, Europe, and the US. Despite the presence of HIV-2 globally, Group B is mainly confined to West Africa.[20][21] Despite its relative confinement, HIV-2 should be considered in all patients exhibiting symptoms of HIV that not only come from West Africa, but also anyone who has had any body fluid transfer with a person from West Africa (i.e. needle sharing, sexual contact, etc.).[22] In viruses that have membranes, membrane-bound viral proteins are synthesized by the host cell and move, like host cell membrane proteins, to the cell surface. When these proteins assemble to form the capsid, part of the host cell membrane is pinched off to form the envelope of the virion. A Pakistani technician takes samples in a laboratory alongside a ribbon promoting World Aids Day in Islamabad on November 30, 2013. Researchers in the United States believe there may finally be an HIV vaccine within 10 years. In the United States, 1.2 million people aged 13 years or older were estimated to have HIV infection in 2012. About 12.8% of them do not know they have HIV infection. About 50,000 new cases are estimated to occur each year in the United States. Most new infections occur in gay and bisexual men, and black men and black women are disproportionately affected (see also HIV in the United States: At A Glance). ^ Jump up to: a b Chou R, Huffman LH, Fu R, Smits AK, Korthuis PT (July 2005). "Screening for HIV: a review of the evidence for the U.S. Preventive Services Task Force". Annals of Internal Medicine. 143 (1): 55–73. doi:10.7326/0003-4819-143-1-200507050-00010. PMID 15998755. Opt-out testing removes the requirement for pretest counseling and detailed, testing-related informed consent. Under the opt-out strategy, physicians must inform patients that routine blood work will include HIV testing and that they have the right to refuse this test. The goal of this strategy is to make HIV testing less cumbersome and more likely to be performed by incorporating it into the routine battery of tests (eg, the first-trimester prenatal panel or blood counts and cholesterol screening for annual examinations). In theory, if testing barriers are reduced, more physicians may offer testing, which may lead to the identification and treatment of more women who are infected with HIV and, if pregnant, to the prevention of mother-to-infant transmission of HIV. This testing strategy aims to balance competing ethical considerations. On the one hand, personal freedom (autonomy) is diminished. On the other hand, there are medical and social benefits for the woman and, if she is pregnant, her newborn from identifying HIV infection. Although many welcome the now widely endorsed opt-out testing policy for the potential benefits it confers, others have raised concerns about the possibility that the requirement for notification before testing will be ignored, particularly in today's busy practice environment. Indeed, the opt-out strategy is an ethically acceptable testing strategy only if the patient is given the option to refuse testing. In the absence of that notification, this approach is merely mandatory testing in disguise. If opt-out testing is elected as a testing strategy, a clinician must notify the patient that HIV testing is to be performed. Refusal of testing should not have an adverse effect on the care the patient receives or lead to denial of health care. This guarantee of a right to refuse testing ensures that respect for a woman's autonomy is not completely abridged in the quest to achieve a difficult-to-reach public health goal. Medications that fight HIV are called antiretroviral medications. Different antiretroviral medications target the virus in different ways. When used in combination with each other, they are very effective at suppressing the virus. It is important to note that there is no cure for HIV. ART only suppresses reproduction of the virus and stops or delays the disease from progressing to AIDS. Most guidelines currently recommend that all HIV-infected people who are willing to take medications should have them initiated shortly after diagnosed with the infection. This delays or prevents disease progression, improves overall health of an infected person, and makes it less likely that they will transmit the virus to their partners. By the end of 1990, over 307,000 AIDS cases had been officially reported with the actual number estimated to be closer to a million. Between 8-10 million people were thought to be living with HIV worldwide.50 As the center of the epidemic has moved from New York and San Francisco to the smaller cities in the South, and from gay white men of means to poorer people of color, L.G.B.T. advocacy and fund-raising has shifted to marriage equality. In 2013, H.I.V. activists persuaded 35 L.G.B.T. leaders to sign a statement and create a video imploring the greater gay community to recommit to the AIDS struggle. The message: “We need you to come back.” But of $168 million in H.I.V./AIDS philanthropic dollars spent in the United States in 2015, $31 million was disbursed to the South, just 19 percent of total H.I.V. philanthropy in the United States; only $26 million directly targeted African-Americans, and just $16 million went directly to gay and bisexual men, according to the organization Funders Concerned About AIDS.

Routine HIV-testing in healthcare facilities also raises legal issues. Most people who are HIV-positive want this information kept confidential. Facilities are free to use HIV testing to control the infection but in most states only with the patient’s informed consent. Some states, such as Illinois, require written consent. The level of protection for medical records varies from state to state. California, for example, has broad protections; under its statutes, no one can be compelled to provide information that would identify anyone who is the subject of an HIV test. However, every state requires that AIDS cases be reported to the CDC, which tracks statistics on the spread of HIV. Whether the name of an HIV-infected person is reported to the CDC depends on state laws and regulations.AIDS and Education Issues in the field of education include the rights of HIV-positive students to attend class and of HIV-positive teachers to teach, the confidentiality of HIV records, and how best to teach young people about AIDS. A few areas have been settled in court: for instance, the right of students to attend classes was of greater concern in the early years of the epidemic and later ceased to be a matter of dispute.

Health care workers are at risk on the job and should take special precautions. Some health care workers have become infected after being stuck with needles containing HIV-infected blood or less frequently, after infected blood comes into contact with an open cut or through splashes into the worker’s eyes or inside their nose.

If doctors suspect to HIV infection, they do a screening test to detect antibodies to HIV. (Antibodies are proteins produced by the immune system to help defend the body against a particular attack, including that by HIV.) In addition, doctors recommend that all adults and adolescents, particularly pregnant women, have a screening test regardless of what their risk appears to be. Anyone who is concerned about being infected with HIV can request to be tested. Such testing is confidential.

Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.

Faced with the worrying increase of AIDS in our country–and the suffering which it creates–the Catholic Church must contribute to the struggle against the disease,” says Monsignor Basile Tapsoba, the bishop of Koudogou in Burkina Faso.

Although one goal of antiviral therapy is to prevent the development of immune suppression, some individuals are already immunosuppressed when they first seek medical care. In addition, others may progress to that stage as a result of resistance to antiviral drugs. Nevertheless, every effort must be made to optimize antiviral therapy in these patients. In addition, certain specific antibiotics should be initiated, depending on the number of CD4 cells, to prevent the complications (that is, the opportunistic infections) that are associated with HIV immunosuppression. Guidelines for the prevention of opportunistic infections can be found at https://aidsinfo.nih.gov/.

Turning things around would mean expanding testing and providing affordable treatment for those who are positive — to stop sickness and dying and also to block transmission of the virus. It would also require getting information and medication, including PrEP, to those most at risk. Even more challenging would be reducing the stigma, discrimination and shame that drive gay and bisexual men to hide their sexuality and avoid the health care system — and making sure providers have adequate resources and understand how to care for H.I.V. patients.

HIV infection is not spread by casual contact (such as hugging and touching), by touching dishes, doorknobs, or toilet seats previously touched by a person infected with the virus, during participation in sports, or by mosquitoes.

Screening antibody tests or newer combination antigen/antibody tests should be offered routinely to adults and adolescents, particularly pregnant women, regardless of their perceived risk. For people at highest risk, especially sexually active people who have multiple partners and who do not practice safe sex, testing should be repeated every 6 to 12 mo. Such testing is confidential and available, often free of charge, in many public and private facilities throughout the world.

Sex with an infected partner without using a condom or other barrier protection can transmit HIV. The virus can enter the body through the lining of the vagina, vulva, penis, rectum, or mouth during sex. Anal intercourse, followed by vaginal intercourse, are the primary risk factors. Oral sex is less likely to transmit HIV, but studies have shown that it can transmit both HIV and other sexually transmitted diseases (STDs).

HIV-positive patients who are taking anti-retroviral medications are less likely to transmit the virus. For example, pregnant women who are on treatment at the time of delivery transmit HIV to the infant about 5% of the time, compared to approximately 20% if medications are not used.

Another way to diagnose HIV infection is to do a special test to detect viral particles in the blood. These tests detect RNA, DNA, or viral antigens. However, these tests are more commonly used for guiding treatment rather than for diagnosis.

Stage I: HIV infection is asymptomatic with a CD4+ T cell count (also known as CD4 count) greater than 500 per microlitre (µl or cubic mm) of blood.[26] May include generalized lymph node enlargement.[26]

Infection with the human immunodeficiency virus (HIV) results in a profound immunosuppression due predominantly to a selective depletion of helper/inducer T lymphocytes that express the receptor for the virus (the CD4 molecule). HIV also has tropism

According to the August 2008 report issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS), as of 2007, approximately 33 million people worldwide are HIV positive. Over half of the 33 million are women and this statistic has remained stable for several years. The highest number of cases is found in sub-Saharan Africa and Southeast Asia.

With passage of the ADA in 1990, Congress gave broad protection to people with AIDS who work in the private sector. In general, the ADA is designed to increase access for disabled persons, and it also forbids discrimination in hiring or promotion in companies with fifteen or more employees. Specifically, employers may not discriminate if the person in question is otherwise qualified for the job. Moreover, they cannot use tests to screen out disabled persons, and they must provide reasonable accommodation for disabled workers. The ADA, which took effect in 1992, quickly emerged as the primary means for bringing AIDS-related discrimination lawsuits. From 1992 to 1993, more than 330 complaints were filed with the U.S. Equal Employment Opportunity Commission (EEOC), which investigates charges before they can be filed in court. Given the lag time needed for EEOC investigations, those cases started appearing before federal courts in 1994 and 1995.

Strategies to reduce the risk of HIV infection include not having sex, limiting your number of sexual partners, never sharing needles, and using condoms the right way every time you have sex. People who are at high risk may take HIV prevention medicines.

Viral load in peripheral blood is used as a surrogate marker of viral replication rate; however, quantitative viral-load assays should not be used as a diagnostic tool. Clinical relevance is as follows:

The person’s immune system is severely damaged, as indicated by a CD4 count of less than 200 cells/mm3. A CD4 count measures the number of CD4 cells in a sample of blood. The CD4 count of a healthy person ranges from 500 to 1,600 cells/mm3.

These are federally approved medical practice guidelines for HIV/AIDS. Each set of guidelines is developed by a panel of experts in HIV care and research that includes health professionals, researchers, and community members. The Panels meet regularly to review the latest clinical research and update the prevention and treatment recommendations.

Opportunistic infections may be caused by bacteria, viruses, fungi, and parasites that are normally controlled by the immune system.[35] Which infections occur depends on what organisms are common in the person’s environment.[28] These infections may affect nearly every organ system.[36]

There are various reasons which can contribute to the failure of the immune system to control HIV infection and prevent AIDS development. By infecting CD4+ T cells, HIV is able to replicate predominantly in activated T cells and paralyse one of the main components of adaptive immune system. HIV can also establish latent infection in CD4+ T cells and remain invisible to CD8+ T cells and therefore replication can occur later in the infection and generate new virions. Antigenic mutation within the T-cell epitopes can affect the binding capacity of MHC molecules to the viral peptides, resulting in the inability of the TCRs to recognise the MHC-peptide complex. Finally, HIV is able to hide from anti-HIV antibodies by expressing non-immunogenic glycans on key antibody epitopes. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]

“How Do You Treat Chlamydia -Chlamydia Dormant”

There is a specific decline in the CD4+ helper T cells, resulting in inversion of the normal CD4/CD8 T-cell ratio and dysregulation of B-cell antibody production. [26, 27] Immune responses to certain antigens begin to decline, and the host fails to adequately respond to opportunistic infections and normally harmless commensal organisms. Because the defect preferentially affects cellular immunity, the infections tend to be nonbacterial (fungal, viral).

Negotiating a maze of unpaved roads in Jackson in the company car, a 13-year-old Ford Expedition with cracked seats and chipped paint, he stopped to drop off H.I.V. medication at a couple’s home. One of the men was H.I.V.-positive, the other negative; they lived in the neighborhood locals call the Bottom, where every fifth or sixth home is abandoned, with broken windows, doors hanging off hinges, downed limbs and dry leaves blanketing front yards. Sturdevant banged on the door of a small house, its yard overgrown with weeds; he knew not to leave the package on the doorstep, where it could be stolen. After a while a young man emerged, shirtless, shrugging off sleep. He had just gotten out of jail. Sturdevant handed him the package, shook his hand and told him to “stay out of trouble.”

The risk of HIV transmission from a pregnant woman to her baby is significantly reduced if the mother takes ART during pregnancy, labor, and delivery and her baby takes ART for the first six weeks of life. Even shorter courses of treatment are effective, though not as optimal. The key is to be tested for HIV as early as possible in pregnancy. In consultation with their physician, many women opt to avoid breastfeeding to minimize the risk of transmission after the baby is born.

The person’s immune system is severely damaged, as indicated by a CD4 count of less than 200 cells/mm3. A CD4 count measures the number of CD4 cells in a sample of blood. The CD4 count of a healthy person ranges from 500 to 1,600 cells/mm3.

TB, or tuberculosis, is a disease caused by bacteria called Mycobacterium tuberculosis that can affect anyone at any age. The bacteria usually attacks the lungs. Particular groups of individuals, however, are shown to be at a higher risk of acquiring the disease than others. These include HIV/AIDS patients, individuals in close contact with TB patients, diabetics, individuals with suppressed immune systems, foreign-born individuals in countries with high TB incidences, healthcare workers, alcoholics, and others. Symptoms of the disease include a persistent cough, fatigue, weight loss, fever, coughing blood, and sweating at night. When an infected individual coughs or sneezes, others nearby are at risk for breathing in the bacteria.

Other tests can detect antibodies in body fluids other than blood, such as saliva, urine, and vaginal secretions. Some of these are designed to be rapid HIV tests that produce results in approximately 20 minutes. These tests have accuracy rates similar to traditional blood tests. OraQuick is an at-home test that uses an oral swab to detect HIV antibodies in oral fluid. Clearview is another rapid HIV test that can detect HIV antibodies in blood or plasma. HIV home-testing kits are available at many local drugstores. Blood is obtained by a finger prick and blotted on a filter strip. Other test kits use saliva or urine. The filter strip is mailed in a protective envelope to a laboratory to be tested. Results are returned by mail within one to two weeks.

In addition to the CD4 lymphocyte count, chest X-rays, Pap smears, and other tests are useful in managing HIV disease. Gay men who engage in receptive anal sex may wish to consider anal Pap smears to detect potential cancers.

At the present time, there is no cure for AIDS. It has proven to be a universally fatal illness. However, most patients survive many years following diagnosis. HAART has dramatically increased the time from diagnosis to death, and research continues in drug treatments and vaccine development.

A family history of primary immunodeficiency is the strongest predictor of a disorder. At birth and for only a few months, babies are partially protected from infections by antibodies transmitted to them by their mothers. Typically, the earlier the age at onset of signs of an immunodeficiency in children, the more severe the disorder. Testing can be done within the first few months, but it is also important to recognize the early signs: recurrent infections and failure to thrive. Initial laboratory screening should include a complete blood count with differential and measurement of serum immunoglobulin and complement levels.

When HIV becomes resistant to HAART, salvage therapy is required to try to suppress the resistant strain of HIV. Different combinations of medications are tried to attempt to reduce viral load. This is often not successful, unfortunately, and the patient will usually develop AIDS and its complications.

Screening of blood donors with tests for both antibody to HIV and HIV RNA has minimized risk of transmission via transfusion. Current risk of transmitting HIV via blood transfusion is probably < 1/2,000,000 per unit transfused in the US. However, in many developing countries, where blood and blood products are not screened for HIV, the risk of transfusion-transmitted HIV infection remains high. Mounzer K, Palella F, Slim J, et al.

They will not only be unable to work, but will also require significant medical care. It is estimated that as of 2007 there were 12 million AIDS orphans.[211] Many are cared for by elderly grandparents.[258] During the latent period, the virus continues to multiply actively. It infects and kills critical infection fighting cells, a type of white blood cell called CD4 cells or T helper cells (T cells). Even though the person has no symptoms, he or she is contagious and can pass HIV to others through the routes described above. At the end of this phase, as the virus overwhelms the CD4 cells, the HIV viral load starts to rise, and the CD4 cell count begins to drop. As this happens, the person may begin to have symptoms as the virus levels increase in the body. This is stage 3. 61.

HIV-1 and HIV-2 are retroviruses in the Retroviridae family, Lentivirus genus. They are enveloped, diploid, single-stranded, positive-sense RNA viruses with a DNA intermediate, which is an integrated viral genome (a provirus) that persists within the host-cell DNA. Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV).[9][10][11] Following initial infection, a person may not notice any symptoms or may experience a brief period of influenza-like illness.[5] Typically, this is followed by a prolonged period with no symptoms.[6] As the infection progresses, it interferes more with the immune system, increasing the risk of common infections like tuberculosis, as well as other opportunistic infections, and tumors that rarely affect people who have working immune systems.[5] These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS).[6] This stage is often also associated with weight loss.[6] PrEP is short for pre-exposure prophylaxis. People who do not have HIV can take a daily pill to reduce their risk of becoming infected. PrEP is not right for everyone and must still be used in combination with safer sex and injection practices. It requires commitment to treatment and does not replace other prevention measures like condom use. It also requires very regular medical visits and frequent blood tests for STDs and HIV, because unknowingly continuing PrEP medication while HIV-infected can lead to resistance and limit HIV treatment options. Resistance has already been reported in a person who became infected while taking PrEP. When he learned he had H.I.V. in 2005, Sturdevant knew little about the virus and was too depressed and ashamed to tell anyone at first. When his partner died the following year, he let the disease consume him. “I was weak, had a fever of 103, couldn’t even keep down water,” he recalled. Sturdevant has shared his story too many times to count, to let young men know that he has been there, too, and to help them understand that they can survive this plague. He also knows that many black gay and bisexual men have been rejected and discarded, and has wrapped his arms around as many as he can grab hold of, treating them like family. Sturdevant has two daughters from an early marriage and three grandchildren, but he says he feels just as strongly about his 16 or so unrelated “children,” most of them living with H.I.V. He feeds them, sometimes houses them, but mostly listens to them. “Young black men feel abandoned and need someone they can believe in and who believes them,” Sturdevant said as he drove past fields of fluffy cotton, his hands resting lightly on the steering wheel. “I told God I want to be able to help guys like me, that didn’t grow up with their father, and they started coming to me, wanting to talk. After a while, they would bring other people to me and say, ‘Dad, can you help him, too?’ ” Parasitic Infections of the biliary tract are a common cause of biliary obstruction in endemic areas.96,97 Tropical and subtropical countries have the highest incidence and prevalence of these infections.

Help us make history. Nef also interacts with SH3 domains. The Vpu protein (p16) influences the release of new virus particles from infected cells.[21] The ends of each strand of HIV RNA contain an RNA sequence called the long terminal repeat (LTR). Regions in the LTR act as switches to control production of new viruses and can be triggered by proteins from either HIV or the host cell. The Psi element is involved in viral genome packaging and recognized by Gag and Rev proteins. The SLIP element (TTTTTT) is involved in the frameshift in the Gag-Pol reading frame required to make functional Pol.[21] These drugs, also referred to as "nukes," interfere with HIV as it tries to replicate and make more copies of itself.

I was the most junior person on staff and had no expertise in the tumor, but none of the senior faculty wanted the job. My first patient, a middle-aged fireman nicknamed Bud, lived a closeted life in West Los Angeles. Not long before he checked in to the hospital, he had started to find growths on his legs that looked like ripe cherries. Then they appeared on his torso, on his face, and in his mouth. Despite strong doses of chemotherapy, the standard treatment for advanced Kaposi sarcoma, his tumors grew, disfiguring him and killing him in less than a year. By 1982, men with highly aggressive kinds of lymphoma had started to arrive at the hospital. They, too, failed to improve with chemotherapy. Patients were dying from an array of diseases that had overcome ravaged immune systems. All my patients had one disorder in common, which the C.D.C., that year, had named acquired-immunodeficiency syndrome, or AIDS. Scientists did not yet know what caused it.

In addition, HIV replication can be detected even in patients with supposedly suppressed replication, as judged by plasma viral load measurements. CD8+ killer T-cell responses to HIV occur in GALT and do not decline with antiviral therapy as much as peripheral measurements do. [33] These findings underscore the limitations of peripheral measurements in what is really a central viral replication.

Counseling for pregnant women:Mother-to-child transmission has been virtually eliminated by HIV testing, treatment with ART, and, in developed countries, use of breast milk substitutes. If pregnant women test positive for HIV, risk of mother-to-child transmission should be explained. Pregnant women who do not accept immediate treatment for their HIV infection should be encouraged to accept therapy to protect the unborn baby, typically beginning at about 14 wk gestation. Combination therapy is typically used because it is more effective than monotherapy and less likely to result in drug resistance. Some drugs can be toxic to the fetus or woman and should be avoided. If women meet criteria for ART, they should begin a regimen tailored to their history and stage of pregnancy and continue it throughout pregnancy. Cesarean delivery can also reduce risk of transmission. Regardless of the antepartum regimen used or mode of delivery, all HIV-infected women should be given IV zidovudine during labor, and after birth, neonates should be given oral zidovudine, which is continued for 6 wk after delivery (see also Prevention of Perinatal Transmission). Some women choose to terminate their pregnancy because HIV can be transmitted in utero to the fetus or for other reasons.

Condoms made of latex provide good protection against HIV (as well as other common sexually transmitted diseases), but they are not foolproof. Oil-based lubricants (such as petroleum jelly) should not be used because they may dissolve latex, reducing the condom’s effectiveness.

In the mid-1990s, AIDS was a leading cause of death. However, newer treatments have cut the AIDS death rate significantly. For more information, see the US Government fact sheet at http://www.niaid.nih.gov/factsheets/aidsstat.htm.

HIV positive women should be counseled before becoming pregnant about the risk to unborn children and medical advances which may help prevent the fetus from becoming infected. Use of certain medications can dramatically reduce the chances that the baby will become infected during pregnancy.

HIV/AIDS is diagnosed via laboratory testing and then staged based on the presence of certain signs or symptoms.[26] HIV screening is recommended by the United States Preventive Services Task Force for all people 15 years to 65 years of age including all pregnant women.[105] Additionally, testing is recommended for those at high risk, which includes anyone diagnosed with a sexually transmitted illness.[29] In many areas of the world, a third of HIV carriers only discover they are infected at an advanced stage of the disease when AIDS or severe immunodeficiency has become apparent.[29]

HIV is now known to spread between CD4+ T cells by two parallel routes: cell-free spread and cell-to-cell spread, i.e. it employs hybrid spreading mechanisms.[89] In the cell-free spread, virus particles bud from an infected T cell, enter the blood/extracellular fluid and then infect another T cell following a chance encounter.[89] HIV can also disseminate by direct transmission from one cell to another by a process of cell-to-cell spread.[90][91] The hybrid spreading mechanisms of HIV contribute to the virus’s ongoing replication against antiretroviral therapies.[89][92]

The HIV DNA copy is incorporated into the DNA of the infected lymphocyte. The lymphocyte’s own genetic machinery then reproduces (replicates) the HIV. Eventually, the lymphocyte is destroyed. Each infected lymphocyte produces thousands of new viruses, which infect other lymphocytes and destroy them as well. Within a few days or weeks, the blood and genital fluids contain a very large amount of HIV, and the number of CD4+ lymphocytes may be reduced substantially. Because the amount of HIV in blood and genital fluids is so large so soon after HIV infection, newly infected people transmit HIV to other people very easily.

Protease is an enzyme that HIV needs to replicate. As the name suggests, protease inhibitors bind to the enzyme and inhibit its action, preventing HIV from making copies of itself. These include atazanavir/cobicistat (Evotaz), lopinavir/ritonavir (Kaletra), and darunavir/cobicistat (Prezcobix).

Human immunodeficiency virus (HIV) is the virus that causes acquired immune deficiency syndrome (AIDS). HIV destroys the body’s immune system and eventually leads to AIDS. People with AIDS develop many diseases and “opportunistic” infections (such as pneumonia, tuberculosis, cancer, and skin infections) that may ultimately lead to death. Prevention is critical. There is no cure for HIV/AIDS, but currently, there are effective treatments that can drastically slow the disease process. If you have been exposed to the HIV virus in any number of ways, you can very easily be tested to determine whether or not you have been infected with the virus.

For every exposure, especially with blood, it is important to test for other blood-borne diseases like hepatitis B or C, which are more common among HIV-infected patients. Reporting to a supervisor, in the case of health care workers, or seeking immediate medical consultation is advisable. For sexual exposures, testing for syphilis, gonorrhea, chlamydia, and other sexually transmitted diseases (STDs) usually should be done because individuals with HIV are more likely to have other STDs. Patients also should be counseled about how to prevent exposure in the future.

A previous estimate¶ of diagnosis delays among persons who received a diagnosis of HIV infection in 2011 indicated that half had been infected for 3.6 years. The median diagnosis delay of 3.0 years among HIV diagnoses in 2015 reflects an absolute reduction of 0.6 years (7 months) and a relative reduction of 17%, representing a considerable decrease over a 4-year period (8). Earlier detection of HIV combined with prompt linkage to care and initiation of antiretroviral treatment enhances preservation of immune function and, if viral suppression is achieved and maintained, reduces risk for sexual transmission of HIV (4). In addition, persons who know they have HIV infection substantially reduce their HIV-related risk behaviors: the prevalence of unprotected anal or vaginal intercourse was found to be 53% lower among persons aware of their HIV status than among those who were unaware of their status (17).

Major advancements in HIV prevention, treatment, and care have put an AIDS-free generation squarely within reach. HIV tests are faster and more reliable than ever before. HIV medications are safer and more effective, and there are now several ways to prevent the spread of HIV, including condoms and Pre-Exposure Prophylaxis (PrEP). PrEP is an HIV prevention strategy that currently involves taking a once daily-pill called Truvada ®. When taken as prescribed, PrEP is safe and highly effective at preventing people from becoming HIV-positive.

The US blood supply is among the safest in the world. Nearly all people infected with HIV through blood transfusions received those transfusions before 1985, the year HIV testing began for all donated blood.

One of the obstacles to treatment of the human immunodeficiency virus is its high genetic variability.[1] HIV can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2). HIV-1 is related to viruses found in chimpanzees and gorillas living in western Africa, while HIV-2 viruses are related to viruses found in the endangered west African primate sooty mangabey.[2] HIV-1 viruses may be further divided into groups. The HIV-1 group M viruses predominate and are responsible for the AIDS pandemic. Group M can be further subdivided into subtypes based on genetic sequence data. Some of the subtypes are known to be more virulent or are resistant to different medications. Likewise, HIV-2 viruses are thought to be less virulent and transmissible than HIV-1 M group viruses, although HIV-2 is known to cause AIDS.

Transmission in pregnancy. High-risk mothers include women sexually active with bisexual men, intravenous drug users, and women living in neighborhoods with a high rate of HIV infection among heterosexuals. The chances of transmitting the disease to the child are higher in women in advanced stages of the disease. Breast feeding increases the risk of HIV transmission as HIV passes into breast milk. The rate of pediatric HIV transmission in the United States had decreased substantially because of HIV testing and improved drug treatment for infected mothers, so fewer than 1% of AIDS cases now occur in children under age 15. In the developing world, mother to infant transmission remains epidemic. In 2006, AIDS was the single most common cause of death in children under age 5 in South Africa, while worldwide children account for about 10% of all AIDS cases.

Schools play a major role in the effort to educate the public on AIDS. Several states have mandated AIDS prevention instruction in their schools. But the subject is controversial: it evokes personal, political, and moral reactions to sexuality. Responding to parental sensitivities, some states have authorized excused absences from such programs. The New York State Education Department faced a storm of controversy over its policy of not allowing absences at parental discretion. Furthermore, at the local and the federal levels, some conservatives have opposed certain kinds of AIDS education. During the 1980s, those who often criticized liberal approaches to sex education argued that AIDS materials should not be explicit, encourage sexuality, promote the use of contraceptives, or favorably portray gays and lesbians. In Congress, lawmakers attached amendments to appropriations measures (bills that authorize the spending of federal tax dollars) that mandate that no federal funds may be used to “promote homosexuality.” In response, the CDC adopted regulations that prohibit spending federal funds on AIDS education materials that might be found offensive by some members of certain communities. Despite the controversy, some communities have taken radical steps to halt the spread of AIDS. In 1991 and 1992, the school boards of New York City, San Francisco, Seattle, and Los Angeles voted to make condoms available to students in their public high school systems.

He said he revealed the diagnosis to people he thought he trusted, but some of them demanded money to keep the information to themselves. paid those people “in the millions,” he said. Later in the show, Lauer said that Sheen told him it was more than $10 million.

Careful investigation has helped scientists determine where AIDS came from. Studies have shown that HIV first arose in Africa. It spread from primates to people early in the 20th century, possibly when humans came into contact with infected blood during a chimpanzee hunt. By testing stored blood samples, scientists have found direct evidence of a human being infected as long ago as 1959.

Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). There are two variants of the HIV virus, HIV-1 and HIV-2, both of which ultimately cause AIDS. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]

In the US in 2015, > 1.1 million people aged ≥ 13 yr were estimated to be living with HIV infection; HIV was undiagnosed in about 15% of them. About 50,000 new cases are estimated to occur each year in the US. Overall, the number of new cases decreased by 19% from 2005 to 2014. In 2016, 39,782 cases were diagnosed. Over two thirds (67% or 26,570) of new infections occurred in gay and bisexual men. Among gay and bisexual men, the number of new infections was 10,223 in black/African American men, 7,425 in Hispanic/Latino men, and 7,390 in white men (2).

After an hour they folded up the table and stuffed the condoms and brochures back into a gym bag, dropped it next to Sturdevant, who was sipping a syrupy cocktail from a can, and headed out to the dance floor. A remix of Rihanna’s “Where Have You Been” came on, so loud the walls shook. Like everyone else, Stevenson and Watson, who are dance coaches and choreographers, had perfected their moves from watching YouTube videos of the Prancing J-Settes. Stevenson bent and thrust, at once explosive, angular and precise. Watson’s face was still as a stone; as he snapped his neck to the side, his waist-length dreadlocks whipped around his head. After a few songs, the music ended as the club prepared for a 1 a.m. drag show. Stevenson, sweaty and breathless, melted into a conversation with other dancers.

Cellular: Cell-mediated immunity is a more important means of controlling the high levels of viremia (usually over 106 copies/mL) at first. But rapid mutation of viral antigens that are targeted by lymphocyte-mediated cytotoxicity subvert control of HIV in all but a small percentage of patients.

HIV/Aids is caused by the Human Immunodeficiency Virus (HIV). HIV is mainly transmitted through sexual intercourse, but can also be passed down from mother to child, acquired via blood transfusion with infected blood, or other methods. Once a person is infected, the virus remains in the body for life. There is no cure for HIV/Aids, but there are drugs that help control the virus, enabling people with symptoms of HIV to live full and healthy lives. There are also various methods to help prevent the spread of the disease.

Virions have a plasma half-life of about 6 h. In moderate to heavy HIV infection, about 108 to 109 virions are created and removed daily. The high volume of HIV replication and high frequency of transcription errors by HIV reverse transcriptase result in many mutations, increasing the chance of producing strains resistant to host immunity and drugs.

It is widely believed that HIV originated in Kinshasa, in the Democratic Republic of Congo around 1920 when HIV crossed species from chimpanzees to humans. Up until the 1980s, we do not know how many people were infected with HIV or developed AIDS. HIV was unknown and transmission was not accompanied by noticeable signs or symptoms.

A person gets HIV when an infected person’s body fluids (blood, semen, fluids from the vagina or breast milk) enter his or her bloodstream. The virus can enter the blood through linings in the mouth, anus, or sex organs (the penis and vagina), or through broken skin.

Some people will wish to use herbal remedies and a Cochrane review was able to find a small number of trials, some of which seemed to have adequate methodology.[14]There was no significant clinical benefit and objective criteria such as CD4 count were unaffected. Since the review there have been a few studies the literature suggesting some benefit from herbal remedies but larger trials are needed.[15, 16]

Most (95%) new infections occur in the developing world. Almost 70% of new HIV infections occur in sub-Saharan Africa, with more than half occurring in women and 1 in 10 occurring in children under 15 years old. However, in many sub-Saharan African countries, the number of new HIV infections decreased by 41% between 2000 and 2014., partly because of international efforts to provide treatment and strategies for prevention.

A person can also get HIV by sharing needles. This means using a needle that has not been cleaned after someone else has used it. Some people who take illegal drugs like heroin and cocaine take these drugs by needle. Some of these people share needles. If one person has HIV and he shares his needles, he can give HIV to other people. But if people have clean needles or if they know how to clean needles, they do not get HIV as much.

Currently, the risk of infection with HIV in the United States through receiving a blood transfusion or blood products is extremely low and has become progressively lower, even in geographic areas with high HIV prevalence.

Guidelines for starting antiviral therapy have been proposed by panels of experts from several groups, including the DHHS (https://aidsinfo.nih.gov/) and IAS-USA. There are similar guidelines for treatment throughout Europe and by the World Health Organization for treatment in resource-limited countries. Until recently a recommendation supporting the start of therapy in those with CD4 cells greater than 500 cells was based upon evidence that ongoing viral replication, even in the setting of high CD4 cell counts, may be associated with damage to the brain, kidneys, heart, and possibly even liver. Along with this rationale, it was clear that newer regimens were easy to take, including a growing number of one-pill-per-day options, with minimal side effects. Another compelling argument that can be made for early therapy is the ability to reduce the risk of transmission to uninfected partners. A study called HPTN 052 demonstrated that amongst couples where one person is HIV-infected and the other is not, those who were on antiretroviral therapy were 96% less likely to transmit HIV to their uninfected partner than those not on treatment. Finally, a large study was recently reported that demonstrated unequivocally that starting therapy even with a CD4 cell count of greater than 500 cells/mm3 was associated with less risk of disease progression than waiting until CD4 cells were less than 350 cells/mm3. This study was called the START study and demonstrated a major reduction in disease progression with early therapy with virtually no increased risk for side effects. Based upon START, HPTN 052 and other accumulated data, currently all major guidelines around the world, including those of the World Health Organization recommend that antiretroviral therapy be initiated in all HIV-infected patients at the time of diagnosis. It is worth noting that these recommendations for universal treatment of HIV-infected patients will be limited by resources available for antiviral treatment in resource-limited countries.

Each year about 5 million people contract AIDS worldwide, and 3 million die of it. Some 40-50 million are estimated to be living with the disease. The gender incidence is approximately equal. The highest prevalence is in some African countries, where as many as 25% of the adult population may test HIV positive; about 70% of the world’s infected population lives in sub-Saharan Africa. The first cases of AIDS were reported in the U.S. in June 1981. During the succeeding 2 decades an estimated 1.4 million people in this country were infected with HIV and 816,149 cases of AIDS and 467,910 deaths were reported to the U.S. Centers for Disease Control and Prevention (CDC). The numbers of new AIDS cases and deaths declined substantially after introduction of combination antiretroviral therapy in the late 1990s. The annual number of new cases of AIDS in the U.S. has remained stable at about 40,000, with 16,000 deaths since 1998. The number of people infected with HIV continues to increase, and of an estimated 1 million, one fourth are unaware that they are infected. In the U.S., AIDS is the leading cause of death among men 25-44 years old, and the fourth leading cause of death among women in the same age group. The development of effective antiretroviral agents (for example, reverse transcriptase inhibitors and protease inhibitors) and of quantitative plasma HIV RNA assays that can monitor progression of disease and response to treatment has shifted the goal of management in AIDS from prophylaxis and treatment of opportunistic infections to achievement of remission through suppressive therapy. Immune compromise is monitored by serial CD4 counts, viral replication by plasma HIV RNA assay (that is, plasma viral load, PVL). Indications for starting antiretroviral therapy are the appearance of symptoms of opportunistic infection, decline of the CD4 count below 350/mm3, or viral load exceeding 30,000 copies/mL. The CD4 count is considered a more sensitive predictor of disease progression than viral load. Empiric treatment may be begun early (within 6 months after conversion to HIV-positive status) in an effort to preserve immune function and mobilize the patient’s own defenses against the virus. But current guidelines advise deferring treatment as long as possible so as to limit induction of drug resistance. Protease inhibitors have been shown to be highly effective antiretroviral agents and standard treatment regimens combining 2 reverse transcriptase inhibitors with 1 protease inhibitor (“triple therapy”) have clearly demonstrated superiority over monotherapy. These drugs are expensive. Regimens are often complex, with varying requirements for fasting and timing of doses, and adverse effects and drug interactions are common. Protease inhibitors have been associated with elevation of cholesterol and triglycerides, insulin resistance, and disfiguring lipodystrophy. In one large study, more than one half of HIV-infected adults under treatment were found to be infected with strains of virus resistant to one or more antiretroviral drugs, and strains of HIV that are resistant to all available protease inhibitors have appeared. The rationale for current AIDS regimens is an effort to eradicate HIV infection by inhibiting spread of virus to new cells until all infected cells have died. However, actual cure seldom if ever occurs. A small number of resting CD4 memory cells in treated patients with undetectable plasma HIV RNA levels harbor HIV proviral DNA capable of replication, and these cells may survive for months or years. Macrophages and CNS neurons may serve as an anatomic sanctuary for HIV into which antretroviral drugs cannot penetrate in adequate concentration. When antiretroviral therapy is initiated early, CD4 helper cell counts rise, CD4 cell activity is preserved, and HIV RNA levels may remain undetectable for long periods. But in about 50% of patients with advanced disease, even multidrug regimens fail to suppress plasma viral RNA to undetectable levels. Many treatment failures result from poor compliance with multidrug regimens. Failure of one therapeutic regimen often precludes success with others because of the high degree of cross-resistance among antiretroviral drugs. After failure of an initial regimen, genotypic testing can be used to identify mutations in the HIV genome that confer resistance to one or more classes of HIV drugs. Many patients remain vulnerable to opportunistic infections despite restoration of CD4 counts to normal, probably because some subpopulations of T cells have been annihilated and cannot be recovered even after HIV has been suppressed. Moreover, even HIV-infected patients with undetectable viral loads must still be considered infectious. In a small set of those infected with HIV, impairment of immunity progresses to AIDS slowly or not at all. CD8 T-cells from such nonprogressors have been found to produce proteins called α-defensins. Evolving standards of treatment in HIV disease include aggressive prophylaxis in pregnancy and after accidental needle stick and sexual assault. Administration of antiretroviral agents to HIV-positive mothers before birth and during labor and delivery, and to newborns for the first 6 weeks of life, markedly decrease the risk of vertical transmission of HIV infection. The risk of HIV infection after occupational parenteral exposure to blood from an HIV-infected patient is approximately 0.3%. Postexposure prophylaxis with antiretroviral agents continued for 28 days have been shown to reduce the risk by 80%. The selection of agents depends on the source patient’s therapeutic history. Efforts to develop a vaccine against HIV have been hampered by the unique properties of the virus and the long incubation period of AIDS. Early in the 21st century, public health authorities sought to make HIV testing a routine part of medical care, to facilitate diagnosis outside formal clinical settings, to prevent new infections by educating people and their sexual partners, and to decrease perinatal HIV transmission through routine HIV testing of pregnant women and of infants whose mothers were not screened.

When he learned he had H.I.V. in 2005, Sturdevant knew little about the virus and was too depressed and ashamed to tell anyone at first. When his partner died the following year, he let the disease consume him. “I was weak, had a fever of 103, couldn’t even keep down water,” he recalled. Sturdevant has shared his story too many times to count, to let young men know that he has been there, too, and to help them understand that they can survive this plague. He also knows that many black gay and bisexual men have been rejected and discarded, and has wrapped his arms around as many as he can grab hold of, treating them like family. Sturdevant has two daughters from an early marriage and three grandchildren, but he says he feels just as strongly about his 16 or so unrelated “children,” most of them living with H.I.V. He feeds them, sometimes houses them, but mostly listens to them. “Young black men feel abandoned and need someone they can believe in and who believes in them,” Sturdevant said as he drove past fields of fluffy cotton, his hands resting lightly on the steering wheel. “I told God I want to be able to help guys like me, that didn’t grow up with their father, and they started coming to me, wanting to talk.

Without treatment, people with AIDS typically survive about 3 years. Common symptoms of AIDS include chills, fever, sweats, swollen lymph glands, weakness, and weight loss. People are diagnosed with AIDS when their CD4 cell count drops below 200 cells/mm or if they develop certain opportunistic illnesses. People with AIDS can have a high viral load and be very infectious.

A major reason that resistance develops is the patient’s failure to correctly follow the prescribed treatment, for example, by not taking the medications at the correct time. If virus remains detectable on any given regimen, resistance eventually will develop. Indeed, with certain drugs, resistance may develop in a matter of weeks, such as with the nucleoside reverse transcriptase inhibitors (NRTIs) lamivudine (Epivir, 3TC) and emtricitabine (Emtriva, FTC), the drugs in the class of nonnucleoside analogue reverse transcriptase inhibitors (NNRTI) such as nevirapine (Viramune, NVP), delavirdine (Rescriptor, DLV), efavirenz (Sustiva, EFV), and rilpivirine (Edurant, RPV), as well as the integrase strand transfer inhibitors (InSTIs) such as raltegravir (Isentress, RAL) and elvitegravir (Vitekta, EVG). Thus, if these drugs are used as part of a combination of agents that do not suppress the viral load to undetectable levels, resistance will develop rapidly and the treatment will lose its effectiveness. In contrast, HIV becomes resistant to other drugs, such as the boosted protease inhibitors (PIs), over months. These drugs are discussed in more detail in subsequent sections, but it is important to note that when resistance develops to one drug, it often results in resistance to other related drugs, so-called cross-resistance. Nevertheless, HIV-infected individuals must realize that antiviral therapy can be and typically is very effective. This is the case even in those who have a low CD4 cell count and advanced disease, as long as drug resistance has not developed.

Until recently a recommendation supporting the start of therapy in those with CD4 cells greater than 500 cells was based upon evidence that ongoing viral replication, even in the setting of high CD4 cell counts, may be associated with damage to the brain, kidneys, heart, and possibly even liver. Along with this rationale, it was clear that newer regimens were easy to take, including a growing number of one-pill-per-day options, with minimal side effects. Another compelling argument that can be made for early therapy is the ability to reduce the risk of transmission to uninfected partners. A study called HPTN 052 demonstrated that amongst couples where one person is HIV-infected and the other is not, those who were on antiretroviral therapy were 96% less likely to transmit HIV to their uninfected partner than those not on treatment. Finally, a large study was recently reported that demonstrated unequivocally that starting therapy even with a CD4 cell count of greater than 500 cells/mm3 was associated with less risk of disease progression than waiting until CD4 cells were less than 350 cells/mm3. This study was called the START study and demonstrated a major reduction in disease progression with early therapy with virtually no increased risk for side effects. Based upon START, HPTN 052 and other accumulated data, currently all major guidelines around the world, including those of the World Health Organization recommend that antiretroviral therapy be initiated in all HIV-infected patients at the time of diagnosis. It is worth noting that these recommendations for universal treatment of HIV-infected patients will be limited by resources available for antiviral treatment in resource-limited countries.

Since then, H.I.V. has been transformed into a treatable condition, one of the great victories of modern medicine. In 1987, the F.D.A. approved AZT, a cancer drug that had never gone to market, for use in H.I.V. patients. At first, it was extortionately priced and was prescribed in high doses, which proved toxic, provoking protest from the gay community. But AZT was able to insinuate itself into the virus’s DNA as it formed, and later it was used in lower doses. Scientists have now developed more than thirty antiretroviral medicines that stop H.I.V. from reproducing in helper T cells.

No firm evidence has shown that the initiation of therapy early in the asymptomatic period is effective. However, very late initiation is known to result in a less effective response to therapy and a lower level of immune reconstitution.

The other issue raised by these studies is the effect of HIV replication on the population dynamics of CD4 T cells. The decline in plasma viremia is accompanied by a steady increase in CD4 T lymphocyte counts in peripheral blood: what is the source of the new CD4 T cells that appear once treatment is started? It seems highly unlikely that they are the recent progeny of stem cells that have developed in the thymus, because CD4 T cells are not normally produced in large numbers from the thymus even at its maximum rate of production in adolescents. Some investigators believe that these cells are emerging from sites of sequestration and add little to the total numbers of CD4 T cells in the body, whereas others advocate their origin from mature CD4 T cells that replicate, and argue that the production of such cells is an ongoing process that compensates for the continual loss of productively infected CD4 T cells.

Every 9.5 minutes, someone in the United States becomes infected. That’s more 56,000 new cases a year. It is estimated that 1.1 million Americans are currently living with HIV. And 1 in 5 are unaware they are infected.

AIDS was first clinically observed in 1981 in the United States.[37] The initial cases were a cluster of injecting drug users and homosexual men with no known cause of impaired immunity who showed symptoms of Pneumocystis carinii pneumonia (PCP), a rare opportunistic infection that was known to occur in people with very compromised immune systems.[218] Soon thereafter, an unexpected number of homosexual men developed a previously rare skin cancer called Kaposi’s sarcoma (KS).[219][220] Many more cases of PCP and KS emerged, alerting U.S. Centers for Disease Control and Prevention (CDC) and a CDC task force was formed to monitor the outbreak.[221]

Human immunodeficiency virus often is diagnosed in women during prenatal antibody screening or in conjunction with screening for sexually transmitted diseases (STDs). Because many women initially identified as infected with HIV are not aware that they have been exposed to HIV and do not consider themselves to be at risk, universal testing with patient notification is more effective than targeted, risk-based testing in identifying those who are infected with HIV (4). The tension between competing goals for HIV testing—testing broadly in order to treat the maximum number of women infected with HIV and, if pregnant, to protect their newborns, and counseling thoroughly in order to maximally protect a woman’s autonomy and right to participate in decision making—has sparked considerable debate.

HIV is a member of the genus Lentivirus,[83] part of the family Retroviridae.[84] Lentiviruses share many morphological and biological characteristics. Many species of mammals are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period.[85] Lentiviruses are transmitted as single-stranded, positive-sense, enveloped RNA viruses. Upon entry into the target cell, the viral RNA genome is converted (reverse transcribed) into double-stranded DNA by a virally encoded reverse transcriptase that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded integrase and host co-factors.[86] Once integrated, the virus may become latent, allowing the virus and its host cell to avoid detection by the immune system.[87] Alternatively, the virus may be transcribed, producing new RNA genomes and viral proteins that are packaged and released from the cell as new virus particles that begin the replication cycle anew.[88]

tarsal tunnel syndrome; TTS pain, paraesthesia and numbness in sole of foot; due to tibial nerve compression within tarsal tunnel; associated with excess foot pronation or rearfoot rheumatoid arthritis; symptoms reproduced by tapping the skin overlying distal medial malleolar area (Tinel’s sign positive); conservative treatment includes valgus filler pads, cobra pads and medial heel wedges, or control of excessive rearfoot pronation with moulded cushioned orthoses worn with bespoke shoes, together with non-steroidal anti-inflammatory drugs and/or disease-modifying antirheumatic drugs; surgical treatment includes decompression procedures to free posterior tibial nerve and excise local fibrous structures (see tarsal tunnel)

Researchers are also trying to switch off a molecule called PD-1, which the body uses to restrain the immune system. Deactivating PD-1 has worked in clinical studies with melanoma and lung-cancer patients, and one patient seems to have been cured of hepatitis C by a single infusion of a PD-1 blocker from Bristol-Myers Squibb.

Pregnancy – some ARVs can harm the unborn child. But an effective treatment plan can prevent HIV transmission from mother to baby. Precautions have to be taken to protect the baby’s health. Delivery through cesarean section may be necessary.

Use a new condom every time you have sex. Use a new condom every time you have anal or vaginal sex. Women can use a female condom. If using lubricant, make sure it’s water-based. Oil-based lubricants can weaken condoms and cause them to break. During oral sex use a nonlubricated, cut-open condom or a dental dam — a piece of medical-grade latex.

The HIV virion enters macrophages and CD4+ T cells by the adsorption of glycoproteins on its surface to receptors on the target cell followed by fusion of the viral envelope with the target cell membrane and the release of the HIV capsid into the cell.[55][56]

Transmission of HIV requires contact with body fluids—specifically blood, semen, vaginal secretions, breast milk, saliva, or exudates from wounds or skin and mucosal lesions—that contain free HIV virions or infected cells. Transmission is more likely with the high levels of virions that are typical during primary infection, even when such infections are asymptomatic. Transmission by saliva or droplets produced by coughing or sneezing, although conceivable, is extremely unlikely.

HIV-1 causes most HIV infections worldwide, but HIV-2 causes a substantial proportion of infections in parts of West Africa. In some areas of West Africa, both viruses are prevalent and may coinfect patients. HIV-2 appears to be less virulent than HIV-1.

During all stages of infection, literally billions of HIV particles (copies) are produced every day and circulate in the blood. This production of virus is associated with a decline (at an inconsistent rate) in the number of CD4 cells in the blood over the ensuing years. Although the precise mechanism by which HIV infection results in CD4 cell decline is not known, it probably results from a direct effect of the virus on the cell as well as the body’s attempt to clear these infected cells from the system. In addition to virus in the blood, there is also virus throughout the body, especially in the lymph nodes, brain, and genital secretions.
