Legionnaires Disease | FAQ

 

What is Legionnaires’ disease?

Legionnaires’ disease is a type of pneumonia that is caused by Legionella, a bacterium found primarily in warm water environments. Both the disease and the bacterium were discovered following an outbreak traced to a 1976 American Legion convention in Philadelphia. Pontiac fever, a flu-like illness, is also caused by Legionella organisms (legionellae), but is not as serious as Legionnaires’ disease. Most people who get Pontiac fever recover within five days, without having to be hospitalized.
