| - Gaëtan Dugas (February 20, 1953 – March 30, 1984), a Canadian who worked for Air Canada as a flight attendant, was one of the first diagnosed AIDS patients. In March 1984, a Centers for Disease Control and Prevention (CDC) 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 him being dubbed "patient zero", although the idea that he initially brought HIV to North America was definitively disproven by researchers in May, 2016; their results were published in October, 2016. He is used as an example in epidemiology of an index case. Dugas traveled the world and had many sexual liaisons with men. At the time, gay culture was largely illegal, underground, and clandestine. Bars and bath houses were social settings for gay and closeted men to meet. The extent to which HIV/AIDS was known about in the early 1980s, how it was spread, or when Dugas was diagnosed are disputed.
