I was in high school and college 1981 - 1990. I was a virgin until I was almost 19 (and in college), and HIV had a lot to do with that decision. First guy I slept with, I made get an HIV test. I got one too as a “good faith” act. We still used condoms.
I also lived in Indiana at the time, and I followed the Ryan White story very closely.
Magic Johnson found out he was HIV positive as the result of a test he was given when he applied for life insurance.
Freddie Mercury found out because he got an AIDS-related illness.
1981 was the year of lots of diagnoses, and AIDS dominating the news. I remember thinking that unless being gay was not only genetic, but made you susceptible to a virus straight people were immune to, it would eventually be everybody’s problem. My money was on the latter.
There was a test in 1985 that the Red Cross began using, and insurance companies were using, but people who suspected they had been exposed were not getting, because it wasn’t available. The Western Blot test came out in 1987, and the rapid test in 1992.
The 1985 ELISA test peroduced a lot of false positives, which was good enough for the Red Cross, but not for testing asymptomatic people. It still took an illness to get a diagnosis. It was the Western Blot that started individual testing.
Freddie Mercury I think, was positive for quite a long time before informing the public-- he informed the press only the day before he died. But I don’t know whether he was disgnosed by the Western Blot, or a related illness.
Magic Johnson was asymptomatic, and his sample was tested by the insurance company, most certainly using the Western Blot.
Mainly preventatives. There are a lot of cultures that simply WILL NOT use condoms, despite their availability, and have high rates of infection.
