    Using HIV-1 sequences preserved in human biological samples along with estimates of viral mutation rates, scientists calculate that the jump from chimpanzee to human probably happened during the late 19th or early 20th century, a time of rapid urbanisation and colonisation in equatorial Africa.

    In parasitology and epidemiology, a host switch (or host shift) is an evolutionary change of the host specificity of a parasite or pathogen.. For example, the human immunodeficiency virus used to infect and circulate in non-human primates in West-central Africa, but switched to humans in the early 20th century.

    HIV made the jump from other primates to humans in west-central Africa in the early-to-mid-20th century. [26] AIDS was first recognized by the U.S. Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade. [21]

    Due to extensive human-mangabey contact in sub-Saharan Africa, SIVsmm has jumped from this species into humans on many occasions, resulting in HIV-2 virus. [29] [30] Because sooty mangabeys, as natural hosts of SIV, do not get sick from SIV, much research has been performed on the species for potential genetic resistance or immunological ...

    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.

    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 ...

    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).
