“AIDS first appeared in equatorial Africa, many scientists now believe. The earliest evidence of its presence on the African continent dates from a plasma sample drawn in 1959 in what was then Leopoldville, the Belgian Congo, and is now Kinshasa, Zaire. Dr. Mirko D. Grmek’s definitive book _History of AIDS_, published in 1990 by Princeton University Press, describes the primary African epidemic’s radiating outward from a region located in Zaire and Rawanda. There’s also a tantalizing connection with monkeys and other primates: Several African species carry a virus related to the human immunodeficiency virus (HIV), which causes AIDS in human beings. Although HIV has yet to be found in monkeys, a “missing link” simian virus much closer to the human virus has been identified in two wild chimpanzees from Gabon. This has led to speculation that a chimp or a monkey with an AIDS virus identical to the human virus will eventually turn up.
Scientists have proposed a grab bag of ideas to explain how the disease may have leapt the vast chasm from monkey to man...”
