Description: | This phlebotomist was in the process of extracting a blood sample from a field-study volunteer’s right antecubital fossa, during a 1979 Legionnaires' disease epidemiologic investigation. Legionnaires' disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness was named Legionella pneumophila. |
