Legionnaires’ disease is a flu-like syndrome with acute fever, chills, malaise, myalgias, headache, or confusion. Nausea, loose stools or watery diarrhea, abdominal pain, cough, and arthralgias also frequently occur. Pneumonic manifestations may include dyspnea, pleuritic pain, and hemoptysis. Bradycardia relative to fever may occur, especially in severe cases. Overall case fatality is low (about 5%) but can reach 40% in patients with hospital-acquired infections, older people, and immunocompromised patients.
