He was noted as an attractive gay man who travelled the world and had many sexual liaisons with other men. At the time the gay culture was largely illegal, underground, and clandestine. Gay bars, and gay bath houses were ubiquitous social settings for gay and closeted men to meet one another worldwide. Other accounts dispute Dugas as being villainous as has been portrayed in popular media, specifically that sexually transmitted diseases were quite common among sexually active men who have sex with men at the time, and the understanding of what the new "gay cancer" was, how it was spread, or when Dugas was diagnosed is all unclear.
Dugas was legally married in Los Angeles on June 27, 1977, in an illegal attempt to receive United States citizenship.
The "Patient Zero" term arose in March 1984 after a Centers for Disease Control and Prevention (CDC) study. The CDC began tracking the sexual liaisons and practices of gay, and bisexual men in California, New York, and some other states. As Dugas was found to be the center of a network of sexual partners, he was dubbed "patient 0".
Patient Zero allegation
A study published in the American Journal of Medicine in 1984 traced many of New York City's early HIV infections, at the time called 'gay cancer', to an unnamed infected gay male flight attendant. Epidemiologists hypothesized that Dugas had carried the virus out of Africa and introduced it into the Western gay community.
Dugas is featured prominently in Randy Shilts's book And the Band Played On, which documents the outbreak of the AIDS pandemic in the United States. Shilts portrays Gaëtan Dugas as having almost sociopathic behavior 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 a year. He claimed to have had over 2,500 sexual partners across North America since becoming sexually active in 1972.
Genetic analysis of HIV provides some support for the Patient Zero theory. Dugas is now believed to be part of a cluster of homosexual men who traveled frequently, were extremely sexually active, and died of AIDS at a very early stage in the epidemic.
However, a number of authorities have since voiced reservations about the implications of the CDC Patient Zero study and characterisations of Dugas as being responsible for bringing HIV to cities like Los Angeles and San Francisco. In the Patient Zero study, the average length of time between sexual contact and the onset of symptoms was 10.5 months. While Shilts's book does not make such an allegation, the rumour that Dugas was the principal disseminator of the virus became widespread. In 1988, Andrew R. Moss published an opposing view in the New York Review of Books.
A November 2007 article in the Proceedings of the National Academy of Sciences dismisses the Patient Zero hypothesis and instead claims that HIV was transmitted from Africa to Haiti in 1966 and from Haiti to the United States in 1969.
In 2014, Radiolab, compiled a report showing that although Dugas had been widely reported as "Patient Zero," he was preceded by many other cases later attributed to HIV/AIDS, and could not be the first case. In 1984, scientists isolated HIV, the virus that leads to AIDS, and noted that the virus, when duplicating itself, made replicating errors, that could be tracked to detect variations in infected individuals over time. Scientists eventually used this information to trace the detection of the virus entering the United States in 1966, when Dugas was still a "virginal adolescent," before entering the U.S., the virus came from the Caribbean country Haiti which is 831 miles off Florida's coast. Scientists trace the origins of HIV from Haiti to West Africa where a subspecies of chimpanzees native to west equatorial Africa had been identified as the original source of the virus.
Human blood samples from 1959, and 1960 from Kinshasa, the capital and the largest city of the Democratic Republic of the Congo, located on the Congo River, led scientists to extrapolated the virus back to the early 1900's, likely 1908 in Africa. Around that time the virus made a major change from another species. Paralleling the HIV discoveries, was primate researches finding Simian immunodeficiency virus (SIV), which was widespread among many species of chimpanzees. In 2006 scientists reported the original of the HIV virus came from a species of chimpanzees that were "penned in" a little corner of Camaroon, in west Central Africa region. Bracketed by the Boumba River to the west, the Sangha River to the east, "this patch of tropical forest is sealed into an inland peninsula to the south by the Ngoko River." The area is about 100 square miles. The best hypothesis, according to Radiolab, is that a Bantu hunter, while processing a newly killed, and infected, chimpanzee, got cut himself and got the animals blood into his body. In the early 1900's the area was experiencing an upheaval as the German Empire took over the land in 1884 naming the colony Kamerun. The hypothesis follows that the infected hunter would have visited or moved to one of the larger inhabited areas in the early 1900s where prostitution and sexual contact would have been easily found.
Using the same virus tracing technologies, they were able to extrapolate about a "chimp patient zero" who existed within a million years ago, although it is likely impossible to further limit the time frame. This chimp would have had to eaten SIV-infected monkeys from two distinct species, a red-capped mangabey, and a spot-nosed guenon. Normally these viruses would have been defeated separately, or never interacted. But in 'chimp zero,' a relatively rare occurrence of pieces of the two viruses combining, and somehow thriving occurred, leading to the virus that later was introduced to humans and became the one HIV virus. Scientists have found a dozen HIV virus strains spread from chimps, monkeys, and a gorilla, but one is responsible for the majority of the human infections causing a high percentage of the almost 36 million people to die as of 2014. This research is being used to study the prevention of other "patient zero" events with other viruses.
