The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs in an attempt 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.
Protease inhibitors (PIs) are medications that act by interfering with enzymes that cleave proteins. Some of the most well known are antiviral drugs widely used to treat HIV/AIDS and hepatitis C. These protease inhibitors prevent viral replication by selectively binding to viral proteases and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles.
Didanosine, sold under the brand name Videx, is a medication used to treat HIV/AIDS. It is used in combination with other medications as part of highly active antiretroviral therapy (HAART). It is of the reverse-transcriptase inhibitor class.
Stavudine (d4T), sold under the brand name Zerit among others, is an antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use with other antiretrovirals.

HIV/AIDS, or human immunodeficiency virus, is considered by some authors a global pandemic. However, the WHO currently uses the term 'global epidemic' to describe HIV. As of 2018, approximately 37.9 million people are infected with HIV globally. There were about 770,000 deaths from AIDS in 2018. The 2015 Global Burden of Disease Study, in a report published in The Lancet, estimated that the global incidence of HIV infection peaked in 1997 at 3.3 million per year. Global incidence fell rapidly from 1997 to 2005, to about 2.6 million per year, but remained stable from 2005 to 2015.
Emtricitabine/tenofovir, sold under the brand name Truvada among others, is a fixed-dose combination antiretroviral medication used to treat and prevent HIV/AIDS. It contains the antiretroviral medications emtricitabine and tenofovir disoproxil. For treatment, it must be used in combination with other antiretroviral medications. For prevention before exposure, in those who are at high risk, it is recommended along with safer sex practices. It does not cure HIV/AIDS. Emtricitabine/tenofovir is taken by mouth.
The AIDS Clinical Trials Group network (ACTG) is one of the largest HIV clinical trials organizations in the world, playing a major role in setting standards of care for HIV infection and opportunistic diseases related to HIV and AIDS in the United States and the developing world. The ACTG is composed of, and directed by, leading clinical scientists in HIV/AIDS therapeutic research. The ACTG is funded by the Department of Health and Human Services, National Institutes of Health through the National Institute of Allergy and Infectious Diseases.
The Division of Acquired Immunodeficiency Syndrome (DAIDS) is a division of the National Institute of Allergy and Infectious Diseases, which is part of the National Institutes of Health. It was formed in 1986 as a part of the initiative to address the national research needs created by the advent and spread of the HIV/AIDS epidemic. Specifically, the Division's mission is to increase basic knowledge of the pathogenesis, natural history, and transmission of HIV disease and to support research that promotes progress in its detection, treatment, and prevention. DAIDS accomplishes this through planning, implementing, managing, and evaluating programs in (1) fundamental basic research, (2) discovery and development of therapies for HIV infection and its complications, and (3) discovery and development of vaccines and other prevention strategies.
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are otherwise rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss.
Darunavir (DRV), sold under the brand name Prezista among others, is an antiretroviral medication used to treat and prevent HIV/AIDS. It is generally recommended for use with other antiretrovirals. It is often used with low doses of ritonavir or cobicistat to increase darunavir levels. It may be used for prevention after a needlestick injury or other potential exposure. It is taken by mouth once to twice a day.
Efavirenz/emtricitabine/tenofovir, sold under the brand name Atripla among others, is a fixed-dose combination antiretroviral medication used to treat HIV/AIDS. It contains efavirenz, emtricitabine, and tenofovir disoproxil. It can be used by itself or together with other antiretroviral medications. It is taken by mouth once a day.
The HIV Prevention Trials Network (HPTN) is a worldwide collaborative clinical trials network that brings together investigators, ethicists, community and other partners to develop and test the safety and efficacy of interventions designed to prevent the acquisition and transmission of HIV. HPTN studies evaluate new HIV prevention interventions and strategies in populations and geographical regions that bear a disproportionate burden of infection. The HPTN is committed to the highest ethical standards for its clinical trials and recognizes the importance of community engagement in all phases of the research process.
The Community Programs for Clinical Research on AIDS (CPCRA) was a program sponsored by National Institutes of Health (NIH) in the United States. Started in 1989, CPCRA was instrumental in some research databases being established. Research from the programs assisted the evaluation of therapies for treating HIV in diverse populations.
HIV drug resistance occurs when microevolution causes virions to become tolerant to antiretroviral treatments (ART). ART can be used to successfully manage HIV infection, but a number of factors can contribute to the virus mutating and becoming resistant. Drug resistance occurs as bacterial or viral populations evolve to no longer respond to medications that previously worked. In the case of HIV, there have been recognized cases of treatment resistant strains since 1989, with drug resistance being a major contributor to treatment failure. While global incidence varies greatly from region to region, there has been a general increase in overall HIV drug resistance. The two main types of resistance, primary and induced, differ mostly in causation, with the biggest cause of resistance being a lack of adherence to the specific details of treatment. These newly created resistant strains of HIV pose a public health issue as they infect a growing number of people because they are harder to treat, and can be spread to other individuals. For this reason, the reaction to the growing number of cases of resistant HIV strains has mostly been to try to increase access to treatment and implement other measures to make sure people stay in care, as well as to look into the development of a HIV vaccine or cure.

The drug was co-developed by Gilead Sciences and Johnson & Johnson's Tibotec division and was approved by the Food and Drug Administration in August 2011, and by the European Medicines Agency in November 2011, for patients who have not previously been treated for HIV. It is available as a once-a-day single tablet.
HIV in pregnancy is the presence of an HIV/AIDS infection in a woman while she is pregnant. There is a risk of HIV transmission from mother to child in three primary situations: pregnancy, childbirth, and while breastfeeding. This topic is important because the risk of viral transmission can be significantly reduced with appropriate medical intervention, and without treatment HIV/AIDS can cause significant illness and death in both the mother and child. This is exemplified by data from The Centers for Disease Control (CDC): In the United States and Puerto Rico between the years of 2014-2017, where prenatal care is generally accessible, there were 10,257 infants in the United States and Puerto Rico who were exposed to a maternal HIV infection in utero who did not become infected and 244 exposed infants who did become infected.
