Investigations into Legionnaires’ disease clusters can be complex.

Legionnaires’ disease is a bacterial pneumonia that people can get after breathing in aerosolized water containing Legionella bacteria. You cannot get Legionnaires’ disease by drinking water that has Legionella. It is not spread from person to person.
Legionnaires’ disease can be severe, so prompt diagnosis and appropriate antibiotic treatment is important.

People with symptoms or general concerns should contact their health care provider.
Most people exposed to Legionella bacteria do not develop Legionnaires’ disease. People at increased risk of infection and severe illness include those ages 50 years and older and current or former smokers. Other risk factors include chronic health conditions such as lung, kidney, or liver disease; diabetes; cancer; and conditions and medications that affect the immune system.
