What is Legionnaires’ Disease?

Legionnaires’ Disease is a severe form of pneumonia caused by the Legionella bacterium. Although Legionella can live in fresh water, it’s often associated with large or complex water systems that are usually found in hospitals, nursing homes or hotels. You cannot get Legionnaires’ Disease from another person. You can only get it by breathing in small water droplets that contain Legionella from sources such as hot tubs or showers.

Symptoms include:

  • Cough
  • Shortness of breath
  • Muscle aches
  • Fever
  • Headache
