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 ...
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).
