What is Legionnaires' Disease?
according to the Mayo Clinic,
Legionnaires' disease is a severe form of pneumonia — lung inflammation usually caused by infection. Legionnaires' disease is caused by a bacterium known as legionella.
You can't catch Legionnaires' disease from person-to-person contact. Instead, most people get Legionnaires' disease from inhaling the bacteria. Older adults, smokers and people with weakened immune systems are particularly susceptible to Legionnaires' disease.
Legionella bacterium also causes Pontiac fever, a milder illness resembling the flu. Separately or together, the two illnesses are sometimes called legionellosis. Pontiac fever usually clears on its own. But untreated Legionnaires' disease can be fatal. Although prompt treatment with antibiotics usually cures Legionnaires' disease, some people continue to experience problems after treatment.
Legionnaires' disease usually develops two to 14 days after exposure to legionella bacteria. It frequently begins with the following signs and symptoms:
- Muscle pain
- Fever that may be 104 F (40 C) or higher
By the second or third day, you'll develop other signs and symptoms that may include:
- Cough, which may bring up mucus and sometimes blood
- Shortness of breath
- Chest pain
- Loss of appetite
- Gastrointestinal symptoms, such as nausea, vomiting and diarrhea
- Confusion or other mental changes
