About the film
Killing Patient Zero is a Canadian documentary film, directed by Laurie Lynd and released in 2019. The film is a portrait of Gaëtan Dugas, the Canadian man who was one of the earliest diagnosed HIV/AIDS patients in North America, but became incorrectly demonized as "patient zero" for the epidemic after his role in the early story of the disease was used to illustrate contact tracing in Randy Shilts's 1987 book And the Band Played On.
