Quote from above: "According to the hpa "Pontiac fever is a mild flu-like illness caused be legionella bacteria, often affecting previously healthy and young individuals. Symptoms can include fever, headaches and muscle aches but, unlike Legionnaires' disease, Pontiac fever does not cause pneumonia. The illness will usually clear up without treatment within two to three days."
