University of Arizona

A research team led by an evolutionary biologist at the University of Arizona publishes a paper in "Nature" on the genetic history of HIV proving that Gaëtan Dugas, the Canadian flight attendant who had been identified for years as "Patient Zero" of the AIDS epidemic in the U.S., did not spread the virus to the country. The study indicates that HIV first spread to the U.S. from the Caribbean around 1970.
