Legionnaires Disease | FAQ


What are the symptoms of Legionnaires’ disease?

Legionnaires’ disease develops within 2 to 10 days after exposure to legionellae. Initial symptoms may include loss of energy, headache, nausea, aching muscles, high fever (often exceeding 104°F), and chest pains. Later, many bodily systems as well as the mind may be affected. The disease eventually will cause death if the body’s high fever and antibodies cannot defeat it. Victims who survive may suffer permanent physical or mental impairment.
