Who gets this disease?
People most at risk of getting sick from the bacteria are usually 65 years of age or older, as well as smokers, or those who have a chronic lung disease like emphysema.
People who have weak immune systems from diseases like cancer, diabetes, or kidney failure are also more likely to get sick from Legionella bacteria. People who take drugs to suppress (weaken) the immune system, such as after a transplant operation, or chemotherapy, are also at higher risk.
What should I do if I think I was exposed to Legionella bacteria?
Most people exposed to the bacteria do not become ill. If you have reason to believe you were exposed to the bacteria, talk to your doctor or local health department. Be sure to mention if you have traveled in the last two weeks.
