In June 1982, a group of cases among gay men in Southern California suggested that the cause of the immune deficiency was sexual and the syndrome was initially called gay-related immune deficiency (or GRID).6
With effort, Jordon sat up slightly, untangling himself from a jumble of sheets. Sturdevant asked how he was doing, and he cataloged a laundry list of what he called his “old man” ailments. “I’ve had everything — diarrhea, hemorrhoids, now this neuropathy,” he said. “My body hates me.” Once a month, his mother or grandmother drove him to medical appointments in Jackson, to receive care from providers experienced in treating people living with H.I.V. and to avoid the small-town gaze at the local facilities; there is no Gay Men’s Health Crisis for him to visit in his small town, as there would be if he lived in New York. “Everybody knows everybody here,” Jordon said. “At the hospital, they know my mom and my brother and my grandmother. I would rather be around people who don’t know me.” Too ashamed to admit that he had the virus, Jordon had told few friends about his diagnosis.
HIV spread from person to person throughout Africa over the course of several decades. Eventually, the virus migrated to other parts of the world. Scientists first discovered HIV in a human blood sample in 1959.
There are three dominant mechanisms for the loss of CD4 T cells in HIV infection. First, there is evidence for direct viral killing of infected cells; second, there is increased susceptibility to the induction of apoptosis in infected cells; and third, there is killing of infected CD4 T cells by CD8 cytotoxic lymphocytes that recognize viral peptides.
The killing stage is more challenging, because the shocked cells carry few H.I.V. antigens, the toxic flags released by pathogenic particles and recognized by the immune system prior to attack. One approach to the killing strategy comes from an unusual type of H.I.V.-positive patient who may carry the virus for decades yet seems not to be disturbed by it. Some of these so-called “élite controllers” possess cytotoxic, or killer, T cells that attack virus-producing cells. The objective is to make every H.I.V. patient into an élite controller through “therapeutic vaccination,” enabling patients to generate killer T cells on their own.
Acquired Immune Deficiency Syndrome (AIDS) is an illness caused by HIV. AIDS is the stage of infection that occurs when your immune system is badly damaged and you become vulnerable to opportunistic infections. Without treatment, people who are living with AIDS typically survive about 3 years. There are medications, such as Non-nucleoside reverse transcriptase inhibitors […]
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.
Currently, there is no vaccine or cure for HIV, but treatments have evolved which are much more effective and better tolerated; they can improve patients’ general health and quality of life considerably, in as little as one pill per day.
Other drugs can prevent or treat opportunistic infections (OIs). ART has also reduced the rate of most OIs. In most cases, these drugs work very well. The newer, stronger ARVs have helped reduce the rates of most OIs.

Although it is important to receive medical treatment for HIV/AIDS, patients may use home remedies or alternative medicine along with standard HIV treatment to improve overall health. It is important to talk to your doctor before trying alternative therapies as some can interfere with the effectiveness of or cause negative effects with HIV drugs.
Usually, HIV infection does not directly cause death. Instead, HIV infection leads to a substantial loss of weight (wasting), opportunistic infections, cancers, and other disorders, which then lead to death.

Circumcision of men: In young African men, circumcision has been shown to reduce their risk of acquiring infection from female partners during vaginal sex by about 50%; male circumcision is probably similarly effective elsewhere. Whether male circumcision reduces HIV transmission from HIV-positive men to women or reduces the risk of acquiring HIV from an infected male partner is unknown.
Unsafe medical injections play a significant role in HIV spread in sub-Saharan Africa. In 2007, between 12 and 17% of infections in this region were attributed to medical syringe use. The World Health Organization estimates the risk of transmission as a result of a medical injection in Africa at 1.2%. Significant risks are also associated with invasive procedures, assisted delivery, and dental care in this area of the world.
Many viruses cause an acute but limited infection inducing lasting protective immunity. Others, such as herpes viruses, set up a latent infection that is not eliminated but is controlled adequately by an adaptive immune response. However, infection with HIV seems rarely, if ever, to lead to an immune response that can prevent ongoing replication of the virus. Although the initial acute infection does seem to be controlled by the immune system, HIV continues to replicate and infect new cells.
Antiretroviral therapy (ART) is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines (called an HIV regimen) every day. (HIV medicines are often called antiretrovirals or ARVs.)
Your doctor will help you choose a regimen based on your overall health and personal circumstances. These medications must be taken consistently and exactly as prescribed. Failure to adhere to therapy guidelines can jeopardize your health.
Once infection has progressed to AIDS, the survival period is usually less than 2 years in untreated patients. Persons in whom the infection does not progress long-term may not develop AIDS for 15 years or longer, although many still exhibit laboratory evidence of CD4 T-cell decline or dysfunction. [79, 80, 81, 82]
Clinical findings Weight loss exceeding 10% of body weight, protracted asthenia, continuous fever for >1 month, diarrhoea >1 month, persistent cough, oropharyngeal candidiasis, relapsing cutaneous herpes, generalised pruritic dermatosis, generalised lymphadenopathy, Kaposi’s sarcoma.
One theory for the discrepancy between GALT and blood measurements is that ongoing viral replication in the lymphoid tissue, and the resulting immune activation, may actually hamper efficient CD4+ T-cell replenishment. 
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).
Paradoxical IRIS typically occurs during the first few months of treatment and usually resolves on its own. If it does not, corticosteroids, given for a short time, are often effective. Paradoxical IRIS is more likely to cause symptoms and symptoms are more likely to be severe when ART is started soon after treatment of an opportunistic infection is started. Thus, for some opportunistic infections, ART is delayed until treatment of the opportunistic infection has reduced or eliminated the infection.
