Well I found "Patient Zero", but it looks like what I heard 35 years ago was almost totally wrong. It is interesting that the term "Patient Zero" started with this case.
Gaëtan Dugas (French: [ɡaetɑ̃ dyɡa]; February 20, 1953 – March 30, 1984), a Canadian flight attendant, was a relatively early HIV patient who once was widely regarded as "patient zero" or the primary case for AIDS in the United States; his case was later found to have been only one of many that began in the 1970s, according to a September 2016 study published in Nature.
In March 1984, a Centers for Disease Control and Prevention (CDC) study tracked the sexual liaisons and practices of gay and bisexual men, especially in California and New York. Dugas was code-named as "patient O" (pronounced "oh", and standing for "Out-of-California"); misconstruing of the letter "O" as 0 (zero) led to the origin of the term "patient zero." The extent to which HIV/AIDS was known about in the early 1980s, how it was spread, or when Dugas was diagnosed are disputed.
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.
