Legionnaires Disease | FAQ


What are the long term side effects of Legionnaires disease? I heard asthma is one side effect.

As with any acute illness, patients who recover from Legionnaires’ disease can suffer long term side effects. The most common are fatigue and lack of energy for several months. However, asthma of new onset is uncommon, although I know of a few cases who have persistent chest x-ray abnormalities with sustained wheezing. It is unclear as to whether this can be blamed solely on Legionnaires’ disease; asthma may be due to a number of stresses besides Legionnaires’ disease.
