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 ...
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

At a time when HIV was still seen as a death sentence, Magic Johnson shocked the world by announcing he was infected. But the bigger shock may have been what happened next. In Episode 9 of "Binge ...
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 ...
