The first known case of HIV in a human a

• The first known case of HIV in a human occurs in a person who died in the Congo, later confirmed as having HIV infection from his preserved blood samples. ^{[2] [3]} The authors of the study did not sequence a full virus from his samples, writing that "attempts to amplify HIV-1 fragments of >300 base pairs (bp) were unsuccessful, . . . However, after numerous attempts, four shorter sequences were obtained" that represented small portions of two of the six genes of the complete AIDS virus.^[3]
• In New York City, "Ardouin A.", a 49-year-old American shipping clerk dies of Pneumocystis carinii pneumonia, a disease closely associated with AIDS. Dr. Gordon Hennigar, who performed the postmortem examination of the man's body, found "the first reported instance of unassociated Pneumocystis carinii disease in an adult" to be so unusual that he pickled Ardouin's lungs for later study. The case was written up in two medical journals at the time, and Hennigar has been quoted in numerous publications saying that he believes Ardouin probably had AIDS.^[4][5]
