Gaëtan Dugas (French: [ɡaetɑ̃ dyɡa]; February 20, 1953 – March 30, 1984) was a Québécois Canadian flight attendant whose role in the early years of the AIDS epidemic attracted considerable attention. Initially identified as a central figure labeled "Patient Zero", Dugas faced allegations of being a primary source of HIV transmission to the United States. This narrative, popularized notably by Randy Shilts' 1987 book And the Band Played On, has been refuted through subsequent scientific scrutiny and historical re-evaluation. Dugas' story highlights the perils of misinformation and the stigma surrounding HIV/AIDS in the 1980s. Despite facing criticism in popular discourse, subsequent studies have provided a more nuanced understanding of Dugas' impact on the epidemic, emphasizing the importance of accuracy and empathy in public health narratives.[1][2][3][4]

Dugas worked as a flight attendant for Air Canada and died in Quebec City in March 1984 as a result of kidney failure caused by AIDS-related infections. In March 1984, a study tracked Dugas, along with other gay and bisexual men, to indicate his role in a particular cluster of 40 AIDS cases in the United States. He was named "Patient O" with "O" standing for "Out-of-California". And the Band Played On used the term "Patient Zero" and put significant focus on Dugas, with media reports expanding his role in the epidemic further. A 2016 study confirmed that Dugas did not bring HIV to the United States, and he was not Patient Zero, via genetic analysis of stored blood samples, supported by historical detective work.[5][6][7][8][9][10][11]

1984 cluster study

[edit]
A 1984 paper[8] linked 40 AIDS patients by sexual contact. Of those patients, Dugas was the first to experience an onset of symptoms of AIDS. In the above graph, Dugas is represented by the number 0. Because Dugas was very forthcoming in helping researchers, Michael Worobey concludes there may be ascertainment bias in the study.[9]

A Centers for Disease Control and Prevention (CDC) study published in The American Journal of Medicine in 1984 titled Cluster of Cases of the Acquired Immune Deficiency Syndrome examined the sexual contacts of gay men infected with AIDS to determine if their histories were consistent with the hypothesis that AIDS was caused by an infectious agent. A graph included with the paper traced the sequence of infection among 40 men and labelled one of the nodes as "Patient 0" (with other nodes including the place of residence and a number indicating the sequence in which they developed AIDS symptoms, such as "NY 14").[8] The paper later stated:

If the infectious-agent hypothesis is true, Patient 0 may be an example of a "carrier" of such an agent. He had had sexual contact with eight other AIDS patients and was the possible source of AIDS for at least three of them. Two of these three men had been his partners before he had overt signs of Kaposi's sarcoma.

The researchers later stated they had originally intended to designate Dugas as "Patient O", with "O" standing for "Out-of-California" but at some point it was changed to a "0".[1]

"Patient Zero" designation

[edit]

Dugas is featured prominently in Randy Shilts' 1987 book And the Band Played On: Politics, People, and the AIDS Epidemic (1987), which documents the outbreak of the AIDS epidemic in the United States. Shilts refers to Dugas as "Patient Zero" and portrays him as having almost sociopathic behaviour by allegedly intentionally infecting, or at least recklessly endangering, others with the virus. Dugas is described as being a charming, handsome sexual athlete who, according to his own estimation, averaged hundreds of sex partners per year.[1] He claimed to have had over 2,500 sexual partners across North America since becoming sexually active in 1972.[12][13] In David France's 2016 book How to Survive a Plague, Shilts' editor expressed his regret for having "made a conscious decision to vilify Dugas in the book and publicity campaign in order to spur sales."[14]

Re-examination

A number of authorities have since voiced reservations about the implications of the CDC's Patient Zero study and characterizations of Dugas as being responsible for bringing HIV to cities such as Los Angeles and San Francisco.[1] In the Patient Zero study, the average length of time between sexual contact and the onset of symptoms was 10+1⁄2 months.[8] While Shilts' book does not make such an allegation, the rumour that Dugas was the principal disseminator of the virus became widespread.[15] In 1988, Andrew R. Moss published an opposing view in The New York Review of Books.[16]

In 2016, a group of researchers led by evolutionary biologist Michael Worobey conducted a genetic study that looked at blood samples taken from gay and bisexual men in 1978 and 1979 as part of a hepatitis B study, and based on the results of the data, concluded that Dugas was not the source of the virus in the United States. "On the family tree of the virus, Dugas fell in the middle, not at the beginning."[17] "Beliefs about Patient Zero," Worobey concludes, "are unsupported by scientific data."[17] Worobey's paper, published in Nature in October 2016, finds "neither biological nor historical evidence that he was the primary case in the United States or for subtype B as a whole."[4][3][18] While Dugas was not the source of HIV infection in the U.S., he was the source of infection for a large number of men, by his own admission.

A study by historian Richard McKay of Cambridge and others identified several causes for the Patient Zero myth. During early CDC analysis of cases in California, patient 057 (Dugas) was nicknamed patient "O" for "Out-of-California", but this was interpreted by others as Patient Zero.[1] Dugas was particularly helpful in tracing his network of partners, providing names and addresses for many of them, which was further expanded because others remembered his distinctive name.[15] Although many of the patients analysed reported in excess of 1,000 sexual partners, most remembered "only a handful" of names, making their contacts to other cases more difficult to trace.[19][18] Richard McKay later extended this study into a book, Patient Zero and the Making of the AIDS Epidemic.[20] This book also contains the most definitive biography of Dugas' life, constructed through numerous interviews with friends, family, and lovers. Robert M. Grant, an AIDS researcher at the University of California, has stated: "No one wants to be the Patient Zero of their village. But this may be helpful because it says, 'Just because you are the first to be diagnosed doesn't mean you started the epidemic.'"[3]

Two films, John Greyson's musical comedy film Zero Patience (1993)[21] and Laurie Lynd's documentary Killing Patient Zero (2019),[22] have discussed the Patient Zero myth around Dugas.[23]
