A blood test can tell if you have HIV infection. Your health care provider can do the test, or you can use a home testing kit. Or to find free testing sites, call the national referral hotline at 1-800-CDC-INFO (1-800-232-4636 in English and en español; 1-888-232-6348 – TTY).
The spread of HIV by exposure to infected blood usually results from sharing needles, as in those used for illicit drugs. HIV also can be spread by sharing needles for anabolic steroids to increase muscle, tattooing, and body piercing. To prevent the spread of HIV, as well as other diseases, including hepatitis, needles should never be shared. At the beginning of the HIV epidemic, many individuals acquired HIV infection from blood transfusions or blood products, such as those used for hemophiliacs. Currently, however, because blood is tested for both antibodies to HIV and the actual virus before transfusion, the risk of acquiring HIV from a blood transfusion in the United States is extremely small and is considered insignificant.
The most common side effect reported with the most recently approved NNRTI, ETR, is rash and it was generally mild and rarely required that medications needed to be stopped. Side effects appear to be uncommon with RPV with some uncertainty as to whether it is associated with various neurologic symptoms.
It is important to document that an exposure has occurred or was likely. A needle stick from a person with HIV or a person likely to have HIV constitutes a significant exposure. Medications should be started immediately. If it is unknown whether the person who is the source of the potentially infected material has HIV, the source person can be tested. Medications that were started immediately in the exposed person can be discontinued if the source person does not turn out to carry HIV. Potentially infectious material splashed in the eye or mouth, or coming into contact with non-intact skin, also constitutes an exposure and should prompt immediate evaluation to determine if medications should be started.
If you take an HIV test during the window period, it’s likely you’ll receive a negative result. But you can still transmit the virus to others. If you think you may have been exposed to HIV, but tested negative during this time, you should repeat the test in three months to confirm.
Painful rash at the injection site and allergic (hypersensitivity) reactions (including rash, fever, chills, nausea, and low blood pressure), numbness and tingling in the hands and feet (peripheral neuropathy), insomnia, and loss of appetite
Although viral load and turnover are usually measured by detecting the viral RNA present in viral particles in the blood, the major reservoir of HIV infection is in lymphoid tissue, in which infected CD4 T cells, monocytes, macrophages, and dendritic cells are found. In addition, HIV is trapped in the form of immune complexes on the surface of follicular dendritic cells. These cells are not themselves infected but may act as a store of infective virions.
Two blood tests are routinely used to monitor HIV-infected people. One of these tests, which counts the number of CD4 cells, assesses the status of the immune system. The other test, which determines the so-called viral load, directly measures the amount of virus in the blood.
The stage of symptomatic infection, in which the body’s immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia).
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
“The key to ending the AIDS epidemic requires people to have either therapeutic or preventive treatments, so repealing the A.C.A. means that any momentum we have is dead on arrival,” said Phill Wilson, chief executive and president of the Black AIDS Institute, a Los Angeles-based nonprofit. “For the most vulnerable, do we end up back in a time when people had only emergency care or no care and were literally dying on the streets? We don’t know yet, but we have to think about it.”
If HIV is left untreated, it may take up to 10 or 15 years for the immune system to be so severely damaged it can no longer defend itself at all. However, the speed HIV progresses will vary depending on age, health and background.
Acute retroviral syndrome usually begins within 1 to 4 wk of infection and usually lasts 3 to 14 days. Symptoms and signs are often mistaken for infectious mononucleosis or benign, nonspecific viral syndromes and may include fever, malaise, fatigue, several types of dermatitis, sore throat, arthralgias, generalized lymphadenopathy, and septic meningitis.
Among persons interviewed through NHBS who were not tested in the past year, most MSM reported that their main reason for not testing was that they believed their risk for infection was low, whereas most persons who inject drugs and heterosexual persons at increased risk reported that they had no particular reason for not testing. In each risk group, at least two thirds of persons who did not have an HIV test had seen a health care provider in the past year (Table 2). Among those who had not tested in the past year and had visited a health care provider, approximately three quarters reported not having been offered an HIV test at any of their health care visits.
It depends on if that person is on treatment and how the virus responds to early treatment. When treatment fails to decrease the replication of the virus, the effects can become life threatening, and the infection can progress to AIDS.
In conclusion, ABCD-1andABCD-3as well as theABCD-3receptorCX3CR1 have been implicated in interfering with human immunodeficiency virus infection, progression, or induced cell death. These observations suggest a potential therapeutic utility of agonists of ABCD-1 and ABCD-3 receptors CCR4 and CX3CR1.
Adherence – HIV treatment is effective if medication is taken as prescribed. Missing even a few doses may jeopardize the treatment. A daily, methodical routine should be programmed to fit the treatment plan around the individual’s lifestyle and schedule. A treatment plan for one person may not be the same treatment plan for another. “Adherence” is sometimes known as “compliance”.
Changes in survival of people infected with HIV. As therapies have become more aggressive, they have been more effective, although survival with HIV infection is not yet equivalent to that in uninfected people. Modified from an original published by Lohse et al (2007), “Survival of persons with and without HIV infection in Denmark, 1995-2005.”

After infection with HIV, it can take from 3 weeks to 6 months for the virus to show up in testing. Re-testing may be necessary. If the moment an individual was most at risk of infection was within the last 6 months, they can have the test immediately. However, the provider will urge that another test is carried out within a few weeks.
A disease caused by the human immunodeficiency virus (HIV) and transmitted by sexual contact or by blood spread on infected needles and other implements. AIDS is not a specifically homosexual disorder. Rather it is a disease of sexually promiscuous populations that harbour large numbers of HIV. The virus attacks a particular group of white cells of the immune system (helper T lymphocytes) causing a severe reduction in the ability of the body to resist infection and certain forms of cancer. The resulting recurrent infections, often with organisms not normally causing disease (opportunistic infectors), can usually be treated, but, to date, no wholly effective treatment for the underlying HIV infection has been developed. Combinations of drugs, including protease inhibitors, reverse transcriptase inhibitors, fusion inhibitors and DNA polymerase inhibitors, can, however, greatly prolong life and have virtually converted AIDS from an inevitably fatal, to a potentially serious chronic disease. The condition may involve many different disorders including a form of pneumonia caused by Pneumocystis carinii , CYTOMEGALOVIRUS infections, widespread herpes simplex infections, widespread thrush (CANDIDIASIS), KAPOSI’S SARCOMA and other malignancies, and brain damage from direct infection of neurons by HIV. The presence of the AIDS virus can be detected by the ELISA and other tests.
Early on a balmy morning last October, Cedric Sturdevant began his rounds along the bumpy streets and back roads of Jackson, Miss. Sturdevant, 52, has racked up nearly 300,000 miles driving in loops and widening circles around Jackson in his improvised role of visiting nurse, motivational coach and father figure to a growing number of young gay men and transgender women suffering from H.I.V. and AIDS. Sturdevant is a project coordinator at My Brother’s Keeper, a local social-services nonprofit. If he doesn’t make these rounds, he has learned, many of these patients will not get to the doctor’s appointments, pharmacies, food banks and counseling sessions that can make the difference between life and death.
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.
Through an approach of outreach, prevention and community information programs, AOC educates the public about HIV prevention while offering free and/or low-cost services to HIV+ individuals and their families.

In 2010, after Oprah Winfrey ran her second show about the down low, again featuring King, Dr. David J. Malebranche, a black physician and one of the country’s foremost experts on H.I.V. and black gay and bisexual men, wrote a heartfelt open letter to the talk-show host. “We are not all self-loathing, secretive, unprotected-sex-having, disease-ridden liars,” Malebranche wrote. He posted the letter on Oprah’s website, and after it was removed, posted it on his own Facebook page. People all over the world shared the post, and it received hundreds of comments.
A safe and effective vaccine for the prevention of HIV infection and AIDS is an attractive goal, but its achievement is fraught with difficulties that have not been faced in developing vaccines against other diseases. The first problem is the nature of the infection itself, featuring a virus that proliferates extremely rapidly and causes sustained infection in the face of strong cytotoxic T-cell and antibody responses. As we discussed in Section 11-25, HIV evolves in individual patients by the selective proliferative advantage of mutant virions encoding peptide sequence changes that escape recognition by antibodies and by cytotoxic T lymphocytes. This evolution means that the development of therapeutic vaccination strategies to block the development of AIDS in HIV-infected patients will be extremely difficult. Even after the viremia has been largely cleared by drug therapy, immune responses to HIV fail to prevent drug-resistant virus from rebounding and replicating at pretreatment levels.

Having HIV is not a sentence to remove oneself from society. It does not limit a person’s physical or mental abilities. Only later, when symptoms develop—as long as ten years from the time of infection—does the disease become increasingly debilitating. In any event, people who are HIV-positive and AIDS-symptomatic are fully able to work, play, and participate in daily life. Moreover, their rights to do so are the same as anyone else’s. The chief barrier to a productive life often comes less from HIV and AIDS than from the fear, suspicion, and open hostility of others. Because HIV cannot be transmitted through casual contact, U.S. law has moved to defend the Civil Rights of those individuals with the disease.

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.
The South also has the highest numbers of people living with H.I.V. who don’t know they have been infected, which means they are not engaged in lifesaving treatment and care — and are at risk of infecting others. An unconscionable number of them are dying: In 2014, according to a new analysis from Duke University, 2,952 people in the Deep South (Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee and Texas) died with H.I.V. as an underlying cause, with the highest death rates in Mississippi and Louisiana. Among black men in this region, the H.I.V.-related death rate was seven times as high as that of the United States population at large.
The US Centers for Disease Control and Prevention (CDC) estimates that about 1.3 million people are living with HIV infection or AIDS; about 15% of them do not know they have it. About 73 percent of the 56,000 new infections each year are in men and about 27 percent are in women. About half of the new infections are in Blacks, even though they make up only 12 percent of the US population. 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.cdc.gov/hiv/topics/surveillance/index.htm.
