Caption:
This photograph, taken around the time of the Legionnaires’ outbreak of 1976, showed Center for Disease Control’s (CDC) Joseph E. McDade, PhD (Lt), and Charles C. Shepard, MD, while in their laboratory. On January 14, 1977, the director of CDC's Laboratory Division, Dr. Shepard, and microbiologist Dr. McDade, isolated the agent that had caused the Legionnaires’ outbreak. Legionnaires’ disease is caused by the bacterium, Legionella pneumophila. The bacterium got its name, when many people who went to a Philadelphia convention of the American Legion, suffered from an outbreak of this disease, a type of pneumonia. Although L. pneumophila existed before 1976, more illness attributed to Legionnaires’ disease, is now being detected. This is because we are now looking for this disease, whenever a patient has pneumonia.
