People at Risk
Most healthy individuals do not become infected with Legionella bacteria after exposure. People at higher risk of getting sick are:
- Older people (usually 50 years of age or older)
- Current or former smokers
- Those with a chronic lung disease (like COPD or emphysema)
- Those with a weak immune system from diseases like cancer, diabetes, or kidney failure
- People who take drugs that suppress (weaken) the immune system (like after a transplant operation or chemotherapy)
