People at Risk

Español: Personas en riesgo

Most healthy people do not become infected with Legionella after exposure. People at higher risk of getting sick are:

  • Older people (usually 50 years or older)
  • Current or former smokers
  • People with a chronic lung disease (like chronic obstructive pulmonary disease or emphysema)
  • People 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)
