Answer

Treat Legionnaires disease intravenously, and consider changing to oral antibiotic therapy with a 10- to 14-day course after patients begin to show signs of clinical improvement. A 21-day course is recommended in patients who are immunocompromised, who have severe underlying disease, or who develop severe Legionella pneumonia.

For immunosuppressed patients, fluoroquinolone therapy is recommended for several reasons. The fatality rate of Legionella pneumonia is high in this patient population.
