The risk of HIV transmission occurring after any potential exposure to bodily fluids is poorly defined. The highest risk sexual activity, however, is thought to be receptive anal intercourse without a condom. In this case, the risk of infection may be as high as 3%-5% for each exposure. The risk is probably less for receptive vaginal intercourse without a condom and even less for oral sex without a latex barrier. Despite the fact that no single sexual exposure carries a high risk of contagion, HIV infection can occur after even one sexual event. Thus, people must always be diligent in protecting themselves from potential infection.

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.

In 2011, HPTN 052, a study of 1,763 couples in 13 cities on four continents funded by the National Institute of Allergy and Infectious Diseases, found that people infected with H.I.V. are far less likely to infect their sexual partners when put on treatment immediately instead of waiting until their immune systems begin to fall apart. This “test and treat” strategy also significantly reduces the risk of illness and death. The data was so persuasive that the federal government began pushing new H.I.V./AIDS treatment guidelines to health care providers the following year. And in 2012, the Food and Drug Administration approved the preventive use of Truvada, in the form of a daily pill to be taken as pre-exposure prophylaxis (commonly called PrEP). It has been found to be up to 99 percent effective in preventing people who have not been infected with H.I.V. from contracting the virus, based on the results of two large clinical trials; an estimated 80,000 patients have filled prescriptions over the past four years.

Sturdevant drove on another 15 minutes to pick up Marq (a shortened version of his name to protect his privacy), a teenager who was still reeling from the H.I.V. diagnosis he received the previous spring. As they headed to and from a doctor’s appointment and a meeting with a counselor, Sturdevant, slow-talking and patient, with eyes that disappear into his cheekbones when he smiles and a snowy beard, gently grilled him, reminding him to stay on his meds. The teenager slumped in the back seat, half listening, half checking his texts. He looked up briefly when Sturdevant told him, “You’ve come a long way. I’m proud of you.” But Marq barely said goodbye as he jumped out of the car in front of a convenience store on an avenue scattered with a pawnshop, a liquor store and several Baptist churches, and he all but admitted he was planning to spend the afternoon smoking weed and looking at Instagram. “Knucklehead,” Sturdevant whispered, as the teenager slammed the door. Pulling off his favorite Dallas Cowboys baseball cap and running a hand over his bald head, Sturdevant added softly, “Breaks my heart.”

The infections that occur with AIDS are called opportunistic infections because they take advantage of the opportunity to infect a weakened host. A person diagnosed with AIDS may need to be on antibiotic prophylaxis to prevent certain opportunistic infections from occurring. The infections include (but are not limited to) the following:

On June 5, 1981, the U.S. Centers for Disease Control and Prevention (CDC) published a report describing a rare lung infection known as Pneumocystis carinii pneumonia in five homosexual men in Los Angeles. Expert review of the cases suggested that the disease likely was acquired through sexual contact and that it appeared to be associated with immune dysfunction caused by exposure to some factor that predisposed the affected individuals to opportunistic infection. The following month the CDC published a report describing an outbreak of cases of a rare cancer called Kaposi sarcoma in homosexual men in New York City and San Francisco. The report noted that in many instances the cancers were accompanied by opportunistic infections, such as P. carinii pneumonia. Researchers subsequently determined that the infections and cancers were manifestations of an acquired immunodeficiency syndrome.

HIV-1 has 6 additional accessory genes: tat, rev, nef, vif, vpu, and vpr. HIV-2 does not have vpu but instead has the unique gene vpx. The only other virus known to contain the vpu gene is simian immunodeficiency virus in chimpanzees (SIVcpz), which is the simian equivalent of HIV. [10] Interestingly, chimpanzees with active HIV-1 infection are resistant to disease. [20]

defective virus one that cannot be completely replicated or cannot form a protein coat; in some cases replication can proceed if missing gene functions are supplied by other viruses; see also helper virus.

Other measures can help. For men, circumcision, an inexpensive, safe procedure, reduces the risk of becoming infected during vaginal intercourse with an infected woman by about half. Whether circumcision reduces the risk of HIV infection in other circumstances is unclear. Because circumcision provides only partial protection against HIV infection, people should also use other measures to prevent HIV infection . For example, if either partner has a sexually transmitted disease or HIV infection, it should be treated, and condoms should be used correctly and consistently.

Acute HIV infection may be associated with symptoms resembling mononucleosis or the flu within 2 to 4 weeks of exposure. HIV seroconversion (converting from HIV negative to HIV positive) usually occurs within months of exposure.

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.

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.

In June 2001, the United Nations (UN) General Assembly called for the creation of a “global fund” to support efforts by countries and organisations to combat the spread of HIV through prevention, treatment and care including buying medication.73

HIV is the virus that’s passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system (called CD4 cells or T cells) that helps protect you from infections. When you don’t have enough of these CD4 cells, your body can’t fight off infections the way it normally can.

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]

Choose less risky sexual behaviors. Anal sex is the highest-risk sexual activity for HIV transmission, especially for the receptive partner (bottom). Oral sex is much less risky than anal or vaginal sex. Sexual activities that don’t involve contact with body fluids (semen, vaginal fluid, or blood) carry no risk of HIV transmission.

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.

In addition to diagnostic blood tests, other blood tests are used to track the course of AIDS in patients that have already been diagnosed. These include blood counts, viral load tests, p24 antigen assays, and measurements of 2-microglobulin (2M).

One of the first high-profile cases of AIDS was the American Rock Hudson, a gay actor who had been married and divorced earlier in life, who died on October 2, 1985 having announced that he was suffering from the virus on July 25 that year. He had been diagnosed during 1984.[264] A notable British casualty of AIDS that year was Nicholas Eden, a gay politician and son of the late prime minister Anthony Eden.[265] On November 24, 1991, the virus claimed the life of British rock star Freddie Mercury, lead singer of the band Queen, who died from an AIDS-related illness having only revealed the diagnosis on the previous day.[266] However, he had been diagnosed as HIV positive in 1987.[267] One of the first high-profile heterosexual cases of the virus was Arthur Ashe, the American tennis player. He was diagnosed as HIV positive on August 31, 1988, having contracted the virus from blood transfusions during heart surgery earlier in the 1980s. Further tests within 24 hours of the initial diagnosis revealed that Ashe had AIDS, but he did not tell the public about his diagnosis until April 1992.[268] He died as a result on February 6, 1993 at age 49.[269]

However, against this pessimistic background, there are grounds for hope that successful vaccines can be developed. Of particular interest are rare groups of people who have been exposed often enough to HIV to make it virtually certain that they should have become infected but who have not developed the disease. In some cases this is due to an inherited deficiency in the chemokine receptor used as co-receptor for HIV entry, as we explained in Section 11-19. However, this mutant chemokine receptor does not occur in Africa, where one such group has been identified. A small group of Gambian and Kenyan prostitutes who are estimated to have been exposed to many HIV-infected male partners each month for up to 5 years were found to lack antibody responses but to have cytotoxic T lymphocyte responses to a variety of peptide epitopes from HIV. These women seem to have been naturally immunized against HIV.

Moreover never loose hope for life as is the only chance which we got, who knows about the second life, if got infected accediently do not loose hope and do the best u can do for yourself and the society.

Transition to these new ARV options has already started in more than 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.

Antenatal testing and the availability of drugs to reduce mother-to-child transmission has resulted in a mother-to-child transmission rate of just 1%. In 2011, the number of infections resulting from mother-to-child transmission was 95. Increasing numbers of HIV-positive women are becoming pregnant and choosing not to have terminations. It is thought this is due to the increasing availability of drugs to prevent mother-to-child transmission.

A deficiency of cellular immunity induced by infection with the human immunodeficiency virus (HIV-1) and characterized by opportunistic diseases, including Pneumocystis jiroveci (formerly carinii) pneumonia, Kaposi sarcoma, oral hairy leukoplakia, cytomegalovirus disease, tuberculosis, Mycobacterium avium complex (MAC) disease, candidal esophagitis, cryptosporidiosis, isoporiasis, cryptococcosis, non-Hodgkin lymphoma, progressive multifocal leukoencephalopathy (PML), herpes zoster, and lymphoma. HIV is transmitted from person to person in cell-rich body fluids (notably blood and semen) through sexual contact, sharing of contaminated needles (as by IV drug abusers), or other contact with infected blood (as in accidental needlesticks among health care workers). Maternal-fetal transmission also occurs. The primary targets of HIV are cells with the CD4 surface protein, including principally helper T lymphocytes. Antibody to HIV, which appears in the serum 6 weeks to 6 months after infection, serves as a reliable diagnostic marker but does not bind or inactivate HIV. Gradual decline in the CD4 lymphocyte count, typically occurring over a period of 10-12 years, culminates in loss of ability to resist opportunistic infections. The appearance of one or more of these infections defines the onset of AIDS. In some patients, generalized lymphadenopathy, fever, weight loss, dementia, or chronic diarrhea occurs much earlier in the course of the infection. Untreated AIDS is uniformly lethal within 2-5 years after the first appearance of an opportunistic infection. Besides prophylaxis against opportunistic infection, standard therapy of HIV infection includes use of nucleoside analogues (for example, didanosine, lamivudine, ribavirin, stavudine, zipovudine), nonnucleoside reverse transcriptase inhibitors (for example, delavirine, efavirenz, nevirapine) and protease inhibitors (for example, atazanavir, crixivan, indinavir, ritonavir, saquinavir).

GALT has been shown to be a site of early viral seeding and establishment of the proviral reservoir. This reservoir contributes to the difficulty of controlling the infection, and efforts to reduce the levels of HIV provirus through sustained antiretroviral therapy (alone or in combination with interleukin-2 activation of resting HIV-infected T cells) have consistently failed.

    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.
