“Pneumocystis Pneumonia — Los Angeles,” in the June 5, 1981 edition of the CDC’s Morbidity and Mortality Weekly Report, was an economical seven paragraph clinical report cataloging five observed cases, accompanied by an explanatory editorial note on the rarity of this fungal disease. It seemed to be nothing out of the ordinary from MMWR, but turned out to be medical literature’s first report of the disease we now know as AIDS.
