Legionnaires’ disease is a serious lung infection caused by the Legionella bacteria, with a case fatality rate of 9%.
Contamination can occur through water or through the respiratory route, through microdroplets suspended in the air. The disease is not contagious from person to person.
The New York City Health Department invites anyone experiencing flu symptoms — fever, chills, body aches, cough — to seek medical attention.
The disease takes its name from the first known cases, which occurred in 1976 at a Philadelphia hotel where the American Legion Veterans Association was holding a conference. Thirty-four people then died.
