What is Legionella?

Legionella are bacteria. There are many disease-causing (pathogenic) species of Legionella bacteria. The pathogenic species most associated with outbreaks of disease is L. pneumophila. It was named after an outbreak at the 1976 American Legion convention. L. pneumophila is the Legionella species that causes legionellosis including Legionnaires’ disease. People can get Legionnaires’ disease when they breathe in small droplets of water in the air that contain Legionella. One out of 10 people who get sick from Legionnaires’ disease will die. Keeping Legionella out of water systems is key to preventing Legionnaires’ disease.
