What is Legionnaires’ Disease?
Legionnaires’ disease is the common name for illnesses caused by Legionnaires’ disease bacteria (LDB). The formal name for the diseases is Legionellosis. Legionnaires’ disease is an infect ion of the lungs that is a form of pneumonia. In addition to Legionnaires ‘ disease, the same bacteria can also cause a flu -like disease called Pontiac fever.
Legionnaires’ disease is named after an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia. There are over 25,000 cases of Legionnaires’ disease each year in the U.S., with more than 4,000 deaths. Most cases are individual cases and are not associated an outbreak (multiple cases at the same location or from the same source). The fatality rate is around 15% – similar to other forms of pneumonia. However, fewer than 5 out of 100 people exposed to LDB -contaminated water develop Legionnaires’ disease.
