Prevalence of HIV/AIDS in Africa, total (% of population ages 15–49), in 2021 (World Bank) HIV / AIDS originated in the early 20th century and remains a significant public health challenge, particularly in Africa. Although the continent constitutes about 17% of the world's population, it bears a disproportionate burden of the epidemic. As of 2023, around 25.6 million people in sub-Saharan ...
This is a timeline of HIV/AIDS, including but not limited to cases before 1980. Pre-1980s See also: Timeline of early HIV/AIDS cases Researchers estimate that some time in the early 20th century, a form of Simian immunodeficiency virus found in chimpanzees (SIVcpz) first entered humans in Central Africa and began circulating in Léopoldville (modern-day Kinshasa) by the 1920s. This gave rise ...
Dugas' story highlights the perils of misinformation and the stigma surrounding HIV/AIDS in the 1980s. Despite facing criticism in popular discourse, subsequent studies have provided a more nuanced understanding of Dugas' impact on the epidemic, emphasizing the importance of accuracy and empathy in public health narratives.

The United States began testing AZT treatments in Africa in 1994, through projects funded by the Centers for Disease Control (CDC), the World Health Organization (WHO) and the National Institutes of Health (NIH). It included testing of over 17,000 women for a medication that prevents mother-to-child transmission of HIV/AIDS.
In 1998, AIDS was the fifth leading cause of death among women aged 25 to 44 in the United States, and the third leading cause of death among African-American women in that age group. [ 81 ] In Africa, HIV was first recognized in sexually active heterosexuals , and AIDS cases in Africa have occurred at least as frequently in women as in men.
HIV-1 group M (responsible for the global pandemic) is estimated to have emerged in humans around 1920 near Kinshasa, then part of the Belgian Congo.This estimation was the result of time-scaled evolutionary models being applied to modern samples and retrieved early samples of HIV-1 (M).
The pandemic strain of HIV-1 is closely related to a virus found in chimpanzees of the subspecies Pan troglodytes troglodytes, which live in the forests of the Central African nations of Cameroon, Equatorial Guinea, Gabon, the Republic of the Congo, and the Central African Republic.
The number of Congolese women living with HIV/AIDS is growing. UNAIDS estimates indicate that, at the end of 2001, more than 60% (670,000) of 1.1 million adults aged 15–49 currently living with HIV/AIDS were women. Infection rates among pregnant women tested in 1999 in major urban areas ranged from 2.7 to 5.4%. Outside the major urban areas ...
