HIV (Human Immunodeficiency Virus) is believed to have originated from chimpanzees in Central Africa and was transmitted to humans in the early 20th century. The virus gradually spread across the globe, leading to the AIDS (Acquired Immunodeficiency Syndrome) pandemic in the 1980s.
The first cases of AIDS were reported in the United States in 1981, primarily among gay men in major cities. The disease was initially known as GRID (Gay-Related Immune Deficiency) before being renamed AIDS. It was soon discovered that the disease was caused by a virus that attacked the immune system, leaving individuals vulnerable to opportunistic infections and cancers.
The discovery of HIV as the causative agent of AIDS was made in 1983 by French researchers Françoise Barré-Sinoussi and Luc Montagnier. The virus was found to be transmitted through bodily fluids such as blood, semen, and breast milk. This led to the development of blood screening tests to prevent the spread of HIV through blood transfusions and organ transplants.
The 1980s and 1990s saw a rapid increase in the number of AIDS cases worldwide, leading to a public health crisis. Stigma and discrimination against individuals living with HIV/AIDS were widespread, and there was a lack of effective treatments for the disease.
In 1996, the introduction of antiretroviral therapy revolutionized the treatment of HIV/AIDS. These medications were able to suppress the virus and prevent the progression to AIDS, leading to a significant decrease in AIDS-related deaths. However, access to these medications remained limited in many parts of the world, particularly in low-income countries.
Efforts to combat the HIV/AIDS pandemic have since intensified, with global initiatives such as the Joint United Nations Programme on HIV/AIDS (UNAIDS) working to increase access to treatment, prevention, and care services. Despite significant progress in the fight against HIV/AIDS, the disease continues to be a major global health challenge, particularly in sub-Saharan Africa where the burden of the disease is highest.

Early 20th Century:
- 1928: HIV-1, the main cause of AIDS, originates in non-human primates in Central and Western Africa.
1950s-1960s:
- Cross-species transmission of HIV-1 to humans occurs through hunting and butchering of infected primates.
- HIV-1 spreads silently within human populations in Central Africa.
1970s:
- 1971: The first cases of Kaposi's sarcoma, a rare cancer associated with immunosuppression, are reported in New York City gay men.
- 1977: The first documented cases of Pneumocystis carinii pneumonia (PCP), an opportunistic infection in people with weakened immune systems, occur in Los Angeles gay men.
1980s:
- 1981: The Centers for Disease Control (CDC) in the United States publishes a report describing five cases of PCP in previously healthy gay men.
- The term "acquired immunodeficiency syndrome" (AIDS) is coined.
- 1983: The Human Immunodeficiency Virus (HIV) is identified as the cause of AIDS.
- 1984: The first blood test for HIV is developed.
- 1985: The Food and Drug Administration (FDA) approves the first antiretroviral drug, azidothymidine (AZT).
- 1987: The World Health Organization (WHO) first reports HIV/AIDS cases in 132 countries.
1990s:
- 1996: Highly active antiretroviral therapy (HAART) revolutionizes treatment, reducing mortality and increasing life expectancy.
- 1998: The first protease inhibitors are approved for HIV treatment, further improving efficacy.
2000s:
- 2003: The Global Fund to Fight AIDS, Tuberculosis, and Malaria is established to provide financial resources to fight HIV/AIDS.
- 2011: The UNAIDS Treatment 2015 target is set to provide antiretroviral therapy to 15 million people by 2015.
- 2014: The FDA approves the first drug for preventing HIV transmission, pre-exposure prophylaxis (PrEP).
2010s-Present:
- 2016: The UNAIDS Fast-Track targets are set to end the AIDS epidemic by 2030.
- 2019: An estimated 38.4 million people worldwide are living with HIV, and 690,000 people died from AIDS-related illnesses.
- 2021: WHO recommends PrEP for all people at substantial risk of HIV infection.
- Ongoing advancements in HIV prevention, treatment, and research continue to improve outcomes and bring the end of the AIDS epidemic closer.
