 This epidemiological study showed how patient zero had infected multiple partners with HIV, and they, in turn, transmitted it to others causing rapid spread of the virus to locations all over the world (Auerbach et al., 1984).The CDC identified Gaëtan Dugas as a carrier of the virus from Europe to the United States, who spread it to other men he had intimate relations with at gay bathhouses.Journalist Randy Shilts subsequently wrote about patient zero, based on Darrow's findings, in his 1987 book "And the Band Played On" which identified patient zero as being Gaëtan Dugas.
