Pneumonia caused by Legionella, known as Legionnaires’ disease or legionellosis, is a relatively common cause of community-acquired pneumonia in adults and is a cause of healthcare-associated pneumonia and pneumonia in immunocompromised adults and children. Legionella is also associated with Pontiac fever, an uncommon, short incubation, self-limited influenza-like illness that primarily affects adults, presenting in epidemic form with symptoms of fever, malaise, myalgia, chills, headache, and pleuritic pain.
