Legionnaires' disease is a type of pneumonia caused by bacteria. Victims usually get it by breathing in mist from water that contains the bacteria. The mist may come from hot tubs, showers or air-conditioning units for large buildings, and it can even come from water fountains. In September 2007, a decorative water fountain located in the lobby of a restaurant n Rapid City, South Dakota, was identified as the source of Legionnaires' disease among restaurant patrons. The bacteria are more likely to invade the lungs if a person is older, smokes, has a history of lung disease, or has a weak immune system. The bacteria don't spread from person to person.

Symptoms of Legionnaires' disease
Symptoms include fever, chills, a cough and sometimes muscle aches and headaches.

A chest x-ray is used to diagnose the Legionnaires pneumonia. Lab tests can detect the specific bacteria that cause Legionnaires' disease.

Legionnaires' disease is serious and can be life-threatening. However, most people recover with antibiotic treatment.
