Ga%C3%ABtan Dugas

Gatan Dugas was a Canadian and early AIDS patient who worked for Air Canada as a flight attendant. In March 1984, a Centers for Disease Control and Prevention study tracking the sexual liaisons and practices of gay and bisexual men in California, New York, and some other states found Dugas to be the center of a network of sexual partners, which led to his being dubbed patient zero, although suspicions that he initially brought HIV to North America were disproven. He is used as an example in epidemiology of an index case.
