Medical illustration of Legionella pneumophilaCDC scientists discovered Legionnaires’ disease in 1976, during one of the largest respiratory disease investigations in U.S. history. CDC’s disease detectives were called upon when people became sick with pneumonia, a serious lung infection, while attending an American Legion convention at a hotel in Philadelphia.
