We’ll cover everything from Legionella bacteria identification to pneumonia symptoms associated with the disease.
What is Legionnaires’ Disease?
Legionnaires’ disease is a severe form of pneumonia caused by Legionella bacteria. It’s not contagious from person to person. Instead, people get sick by breathing in small droplets of water containing the bacteria. These droplets can come from sources like:
* Cooling towers
* hot tubs and spas
* Large plumbing systems
* Decorative fountains
* Hospital and healthcare facilities water systems
The disease gets its name from a 1976 outbreak at an american Legion convention in Philadelphia. While initially alarming, understanding the transmission method is key to prevention. Legionella infection can range in severity from mild flu-like symptoms to severe, life-threatening pneumonia.
Symptoms of Legionnaires’ Disease & Legionella Pneumonia
Recognizing the symptoms of Legionnaires’ disease is crucial for early diagnosis and treatment. Symptoms typically appear 2 to 10 days after exposure to the bacteria and can mimic other respiratory illnesses. Common symptoms include:
- Cough
- Shortness of breath
- Fever (often high, 104°F or higher)
- Muscle aches
- Headache
- Fatigue
- Loss of appetite
- Sometimes, gastrointestinal symptoms like nausea, vomiting, or diarrhea.
