Answer

The possibility of Legionella infection should always be considered when evaluating CAP, because delayed treatment significantly increases mortality. The most prevalent causative organism is S pneumoniae, regardless of the host or the setting. Empiric antibiotic therapy must be selected with this micro-organism in mind.
