A lecture Fauci gave at the National Institutes of Health on Nov. 4, 1984, on AIDS.

The clip is from a lecture Fauci gave at the National Institutes of Health on Nov. 4, 1984, on AIDS. He talked about how the disease first emerged in the United States in 1979 and how it was recognized as a new disease in 1981.

Here’s the relevant part of what he said; the portion that was shared in the Instagram post is in italics:

"I’ll get to in some of the later slides how this disease, which we surmised early on, started off in the male homosexual population in this country. Not that there was anything intrinsically different or wrong or what-have-you about homosexuality. It was very simple; it’s straightforward epidemiology. You take an infectious agent and you introduce it into a population in which the spread among those individuals — if it’s sexual-contact spread — it’s a perfect set-up to spread."
