Legionnaires' Disease and Pontiac Fever - Topic Overview

How are they treated?

Most cases of Legionnaires' disease can be treated successfully with antibiotics. Treatment usually lasts at least 5 days.

Fever tends to improve or go away within the first few days. A cough may take longer to disappear. But in general you should start to feel better within the first few days of treatment. Complete recovery can take from 2 to 4 months.

Pontiac fever will go away without treatment. To reduce fever and muscle aches, drink plenty of fluids and consider taking over-the-counter pain relievers like acetaminophen (Tylenol, for example) or nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs include ibuprofen (such as Advil and Motrin), naproxen (such as Aleve), and aspirin. Do not give aspirin to anyone younger than 20 because of the risk of Reye syndrome. Be safe with medicines. Read and follow all instructions on the label.

What should you do if you think you were exposed to the bacteria?

Most people who are exposed to the bacteria don't become ill. But if you believe you were exposed, talk to your doctor or local health department. Be sure to tell them where you think you were exposed and if you have traveled in the last 2 weeks. This information will help them correctly diagnose and treat the disease, locate the source of the bacteria, and prevent others from being exposed to it.
