DID YOU KNOW?
Legionnaires' disease got its name from an outbreak at an American Legion convention in 1976. [3]
STAY INFORMED
- Legionnaires' disease is a severe form of pneumonia caused by the Legionella bacteria. [1]
- The same bacteria can also cause a milder illness known as Pontiac fever, which typically resolves on its own. [1]
- Symptoms may begin 2–10 days after exposure and include fever, chills, cough, muscle aches, and shortness of breath. [1]
- Infection occurs from inhaling water vapor or mist containing the bacteria, not from person-to-person contact.
HELPFUL TIPS
1. Maintain Water Systems
- Ensure proper disinfection and maintenance of hot tubs, showers, fountains, and HVAC cooling towers. [2]
2. Don’t Use Plain Water in Windshield Wiper Fluid Tanks
- Legionella can grow in warm, stagnant fluid. Always use washer fluid that contains a disinfecting agent. [2]
3. Stay Informed With CDC Guidance
- The CDC offers prevention checklists and resources for building managers and homeowners. Visit cdc.gov/legionella.
HEALTH REMINDER
Legionnaires’ disease is serious — especially for older adults, smokers, and those with weakened immune systems. Regular cleaning, proper system maintenance, and public awareness are key to prevention.
