What are the usual symptoms of Legionnaires' disease?
Patients with Legionnaires' disease usually develop a fever, chills, and a
cough. The cough may either be dry or produce sputum. Some patients with
Legionnaires' disease also have muscle aches, headache,
tiredness, loss of
appetite, and occasionally diarrhea.
Legionnaires' disease can cause a severe pneumonia, seriously affect breathing, even lead to respiratory failure and adult respiratory distress syndrome (ARDS). In some cases, the heart rate is slower than expected for the degree of fever. There are no specific symptoms that directly identify
Legionnaires' pneumonia. Legionnaires' pneumonia presents in a manner similar to
Chlamydia pneumonia and Mycoplasma pneumonia, so-called atypical pneumonias (previously referred to as "walking pneumonia"). These are referred to as atypical because, unlike typical pneumonia (as characterized by Streptococcus pneumonia), which involves high, spiking fevers, sudden onset, cough, and purulent sputum and often chest pain and a localized infiltrate on
They can have a less virulent presentation despite very diffuse infiltrates on chest X-ray.
People with Pontiac fever experience a self-limiting influenza-like illness with fever, chills, headache, and muscle aches but, by definition, do not have pneumonia. Affected individuals generally recover in
two to five days without treatment.
