Overview

History

Legionnaires’ disease typically presents with pneumonia, which usually requires hospitalization and can be fatal in 10%–15% of cases. Symptom onset occurs 2–14 days after exposure. In outbreak settings, <5% of people exposed to the source of the outbreak develop Legionnaires’ disease.

Pontiac fever is milder than Legionnaires’ disease and presents as an influenza like illness, with fever, headache, and myalgias, but no signs of pneumonia. Pontiac fever can affect healthy people, as well as those with underlying illnesses, and symptoms occur within 72 hours of exposure. Most patients fully recover. Up to 95% of people exposed in outbreak settings can develop symptoms of Pontiac fever.

Common Symptoms

Symptoms of Legionnaires' disease may include:
