On June 5, 1981, the U.S. Centers for Disease Control and Prevention (CDC) published a Morbidity and Mortality Weekly Report (MMWR), describing cases of a rare lung infection, Pneumocystis carinii pneumonia (PCP), in five young, previously healthy, gay men in Los Angeles. This marked the first official reporting of what will become known as the AIDS epidemic.
AIDS.gov has published a History of HIV/AIDS Timeline that reflects the history of the domestic AIDS epidemic from its origins in illness, fear, and death to our present, hope-filled years. Originally created in 2011 to highlight milestones of “30 Years of AIDS,” the timeline has recently been updated with entries through 2015.
