The defining plague of the late twentieth century announced itself in the federal record with a two-page bulletin: five young men in Los Angeles with a pneumonia that should not have touched them, reported in June 1981. The episode follows years of official silence, Surgeon General Koop's household mailing, activists like ACT UP, AZT and combination therapy, PrEP, and PEPFAR. The cure and prevention came largely from outside government.
The Gallo and Montagnier priority dispute was long and bitter, and the 2008 Nobel went to Barré-Sinoussi and Montagnier. The administration's response was widely criticized as slow, PEPFAR's 2025 status is still developing, and HIV's origin is a natural zoonotic one.
