AIDS Invaded US in 1969, Study Finds.

Long before storied ‘Patient Zero‘ Gaëtan Dugas [previously] scientists now believe that HIV/AIDS “invaded the United States in about 1969 from Haiti, carried most likely by a single infected immigrant who set the stage for it to sweep the world in a tragic epidemic.” A new study to be published this week in the Proceedings of the National Academy of Sciences
indicates that researchers conducted a genetic analysis of stored blood
samples from early AIDS patients and now believe that HIV first entered
the United States in the 1960s — and not the 1980s. Other “studies suggest the
virus first entered the human population in about 1930 in central
Africa, probably when people slaughtered infected chimpanzees for
meat.”
