Diagnosed with kaposi"s sarcoma in june 1980. (died in 1984). In 1982, the cdc linked him to 9 of the first 19 cases in los angeles, 22 cases in nyc and 9 more in 8 other cities. Total of 40 of the first 248 cases in the us. Hiv isolated from virtually every patient with aids; has been cultured or confirmed by molecular techniques (pcr). Accidental exposure to hiv in lab workers resulted in development of aids (no other risk factors).

The only thing that is found in all people who have aids, is that they are hiv positive.
