HIV spread earlier than believed; Patient 0 a myth, study says

HIV likely landed in the United States a full decade before the first AIDS reports made headlines, according to a report released Wednesday that also strongly dismisses the long-held myth that a single man, a flight attendant notoriously known as Patient Zero, was responsible for the domestic epidemic. The report, published Wednesday in the journal Nature, traces the lineage of HIV from Africa to Haiti to New York and, finally, San Francisco. The virus seems to have arrived in New York around 1971, and in San Francisco five years later. By the time doctors were reporting the first AIDS cases in 1981, the virus would have been deeply embedded in cities all over the country. The fact that HIV predated those first AIDS reports - and that the so-called Patient Zero could not have been responsible for the epidemic - has long been known by AIDS researchers. But the new paper ... provides perhaps the most detailed genetic history of the virus geographic movement. The new study, when coupled with previous work, gives a fairly clear picture of HIVs global travel, said co-author Michael Worobey, an evolutionary biologist at the University of Arizona at Tucson. He said studies suggest the virus moved from chimpanzees to humans in the early 20th century, but languished in rural villages for decades before passing into Kinshasa, the capital of Congo. From Kinshasa it may have spread throughout sub-Saharan Africa, and finally moved to the Caribbean, including Haiti, in the mid-1960s.
