Antibiotics are used to fight the infection. Treatment is started as soon as Legionnaire's disease is suspected, without waiting for confirmation by lab test.

Antibiotics commonly used to treat this condition include:

• Quinolones (ciprofloxacin, levofloxacin, moxifloxacin, or gatifloxacin)
• Macrolides (azithromycin, clarithromycin, or erythromycin)

Other treatments may include:

• Fluid and electrolyte replacement
• Oxygen (given through a mask or breathing machine)

Expectations (prognosis):

Legionairre's disease can lead to death. The death rate increases in those with underlying diseases. The death rate for patients who develop Legionnaire's disease while in the hospital is close to 50%, especially when antibiotics are started late.

Complications:

• Lung failure
• Death
