What is Legionnaires’ disease?

Legionnaires’ disease is a severe form of pneumonia typically caused by the bacterium, Legionella.

The disease can be contracted from breathing small droplets of water in the air containing Legionella. Older adults, smokers, and people with weakened immune systems are particularly susceptible to Legionnaires’ disease.
