Air Canada Flight Attendant Gaetan Dugas Wasn’t AIDS ‘Patient Zero’

Air Canada Flight Attendant Gaetan Dugas Wasn't AIDS 'Patient Zero'

(Newser) – The French Canadian flight attendant dubbed “Patient Zero” in the AIDS epidemic in North America was no such thing, researchers say.In a study published in the journal Nature, researchers analyzed HIV genomes and determined that the virus came to the US from Haiti around 1971 and had already infected many people in cities including New York and San Francisco before Air Canada flight attendant Gaetan Dugas contracted it.CDC scientist William Darrow says that when he was investigating the emerging epidemic in Los Angeles in the early ’80s, he identified patients by code (e.g., “LA1” and “LA2” for two men in Los Angeles)—and Dugas was the letter “O” for “outside of California,” not the numeral zero.

Non esiste ancora nessun paziente zero nella storia dell’epidemia di AIDS.La ricerca coordinata da Michael Worobey, dell’Università Arizona di Tucson, pubblicata su Nature, non solo riscrive la storia del virus ma scagiona definitivamente – dopo 30 anni – lo steward dell’Air Canada, Gaetan Dugas, additato come il primo responsabile della diffusione del virus Hiv negli Stati Uniti.Dugas fu ‘incriminato’ da uno studio pubblicato su The American Journal of Medicine nel 1984, dove venivano ricostruiti i rapporti sessuali di cinquanta tra i primi infettati.
