The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
HIV-positive people, seropositive people or people who live with HIV are people infected with the human immunodeficiency virus (HIV), a retrovirus which if untreated may progress to acquired immunodeficiency syndrome (AIDS).
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood, in order to replicate inside a patient and produce additional normal blood cells. HSCT may be autologous, syngeneic, or allogeneic.
C-C chemokine receptor type 5, also known as CCR5 or CD195, is a protein on the surface of white blood cells that is involved in the immune system as it acts as a receptor for chemokines.
This is a timeline of HIV/AIDS, including but not limited to cases before 1980.
AIDS-defining clinical conditions is the list of diseases published by the Centers for Disease Control and Prevention (CDC) that are associated with AIDS and used worldwide as a guideline for AIDS diagnosis. CDC exclusively uses the term AIDS-defining clinical conditions, but the other terms remain in common use.
The human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system. It can be managed with treatment. Without treatment it can lead to a spectrum of conditions including acquired immunodeficiency syndrome (AIDS). Effective treatment for HIV-positive people involves a life-long regimen of medicine to suppress the virus, making the viral load undetectable. There is no vaccine or cure for HIV. An HIV-positive person on treatment can expect to live a normal life, and die with the virus, not of it.
Taiwan's epidemic of HIV/AIDS began with the first case reported in December 1984. On 17 December 1990 the government promulgated the AIDS Prevention and Control Act. On 11 July 2007, the AIDS Prevention and Control Act was renamed the HIV Infection Control and Patient Rights Protection Act.
Long-term nonprogressors (LTNPs), are individuals infected with HIV, who maintain a CD4 count greater than 500 without antiretroviral therapy with a detectable viral load. Many of these patients have been HIV positive for 30 years without progressing to the point of needing to take medication in order not to develop AIDS. They have been the subject of a great deal of research, since an understanding of their ability to control HIV infection may lead to the development of immune therapies or a therapeutic vaccine. The classification "Long-term non-progressor" is not permanent, because some patients in this category have gone on to develop AIDS.
Kaposi's sarcoma (KS) is a type of cancer that can form masses on the skin, in lymph nodes, in the mouth, or in other organs. The skin lesions are usually painless, purple and may be flat or raised. Lesions can occur singly, multiply in a limited area, or may be widespread. Depending on the sub-type of disease and level of immune suppression, KS may worsen either gradually or quickly. Except for Classical KS where there is generally no immune suppression, KS is caused by a combination of immune suppression and infection by Human herpesvirus 8.
Gero Hütter is a German hematologist. Hütter and his medical team transplanted bone marrow deficient in a key HIV receptor to a leukemia patient, Timothy Ray Brown, who was also infected with human immunodeficiency virus (HIV). Subsequently, the patient's circulating HIV dropped to undetectable levels. The case was widely reported in the media, and Hütter was named one of the "Berliners of the year" for 2008 by the Berliner Morgenpost, a Berlin newspaper.
Georges Mathé was a French oncologist and immunologist. In November 1958, he performed the first successful allogeneic bone marrow transplant ever performed on unrelated human beings.
Timothy Ray Brown was an American considered to be the first person cured of HIV/AIDS. Brown was called "The Berlin Patient" at the 2008 Conference on Retroviruses and Opportunistic Infections, where his cure was first announced, in order to preserve his anonymity. He chose to come forward in 2010. "I didn't want to be the only person cured," he said. "I wanted to do what I could to make [a cure] possible. My first step was releasing my name and image to the public."
The Berlin patient is an anonymous person from Berlin, Germany, who was described in 1998 as exhibiting prolonged "post-treatment control" of HIV viral load after HIV treatments were interrupted.
HIV/AIDS research includes all medical research that attempts to prevent, treat, or cure HIV/AIDS, as well as fundamental research about the nature of HIV as an infectious agent and AIDS as the disease caused by HIV.
Stephen Lyon Crohn, also known as "the man who can't catch AIDS", was a man notable for a genetic mutation that caused him to be immune to AIDS. He was a great-nephew of Burrill Bernard Crohn, for whom Crohn's disease is named.
A small proportion of humans show partial or apparently complete innate resistance to HIV, the virus that causes AIDS. The main mechanism is a mutation of the gene encoding CCR5, which acts as a co-receptor for HIV. It is estimated that the proportion of people with some form of resistance to HIV is under 10%.

Professor Ravindra "Ravi" Kumar Gupta is a professor of clinical microbiology at the Cambridge Institute of Therapeutic Immunology and Infectious Disease at the University of Cambridge. He is also a member of the faculty of the Africa Health Research Institute in Durban, South Africa.
Paul Edmonds, is an American recognized as the oldest individual to achieve remission from both HIV and leukemia. He is known as the "City of Hope Patient" from the hospital where he underwent treatment in Duarte, California. Diagnosed with HIV in 1988 at the age of 33, Edmonds spent over three decades living with the virus until 2018, when he faced a new challenge—a diagnosis of myelodysplastic syndrome, evolving into acute myelogenous leukemia. His journey to recovery, culminating in a stem cell transplant in 2019, at age 63, involved a donor with a rare genetic mutation resistant to most HIV strains. Edmonds ceased his HIV treatment in March 2021, with subsequent tests revealing no evidence of HIV in his body. Edmonds is among the five known individuals cured of HIV through stem cell transplantation for their blood cancer, alongside the Berlin Patient, London Patient, Düsseldorf Patient, and New York Patient.
