1981 - First report on AIDS
The June 5, 1981 issue of Morbiity and Mortality Weekly Report published a report entitled 5 cases of Pneumocystis carinii pneumonia (PCP) - Los Angeles. The report prompted the Centers for Disease Control to instigate reporting from New York City, San Francisco and other cities, and in June 1981 to form an investigative team to look into risk factors and to define this disease for national surveillance. What started as five identified cases in Los Angeles has grown to an estimated 38.6 million cases worldwide in 2005, according to the Joint United Nations Programme on HIV/AIDS.
