Origin of HIV
Main article: AIDS origin
AIDS was first reported June 5, 1981, when the U.S. Centers for Disease Control and Prevention recorded a cluster of Pneumocystis carinii pneumonia (now classified as Pneumocystis jiroveci pneumonia) in five homosexual men in Los Angeles.[121] Health authorities soon realized that nearly half of the people identified with the syndrome were not homosexual men.
Three of the earliest known instances of HIV infection are as follows:
1. A plasma sample taken in 1959 from an adult male living in what is now the Democratic Republic of the Congo.[122]
2. HIV found in tissue samples from a 15 year old African-American teenager who died in St. Louis in 1969.[123]
3. HIV found in tissue samples from a Norwegian sailor who died around 1976.[124]
Two species of HIV infect humans: HIV-1 and HIV-2. HIV-1 is more virulent and more easily transmitted. HIV-1 is the source of the majority of HIV infections throughout the world, while HIV-2 is not as easily transmitted and is largely confined to West Africa.[125] Both HIV-1 and HIV-2 are of primate origin. The origin of HIV-1 is the Central Common Chimpanzee (Pan troglodytes troglodytes) found in southern Cameroon.[126] It is established that HIV-2 originated from the Sooty Mangabey (Cercocebus atys), an Old World monkey of Guinea Bissau, Gabon, and Cameroon.
Most experts believe that HIV probably transferred to humans as a result of direct contact with primates, for instance during hunting or butchery.[127] A more controversial theory known as the OPV AIDS hypothesis suggests that the AIDS epidemic was inadvertently started in the late 1950s in the Belgian Congo by Hilary Koprowski's research into a polio vaccine.[128] [129] According to scientific consensus, this scenario is not supported by the available evidence.[130] [131] [132]
