Legionnaire’s Disease


“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.”




“The bacterium got its name after a 1976 outbreak, when many people who went to a Philadelphia convention of the American Legion suffered from this disease, a type of pneumonia (lung infection). Although this type of bacterium was around before 1976, more illness from Legionnaires’ disease is being detected now.”-CDC


Legion-ella translates into “small army” and “pneumo-philla” into “likes lung” This disease attacks the lung tissue and can cause an often fatal form on pneumonia. The bacterium was often found at construction sites and demolition sites. Several water samples were found in air-conditioning leaks and cooling towers. Amazingly, Legionella can last up to a year in tap water. Most cases of Legionnaire’s disease are treated on suspicion alone, and then confirmed by blood sample. It is noticed by a rising level of antibodies.

The treatment of Legionnaire’s disease is treated with the antibiotic erythromycin, and doubled and given the drug rifampin for those suffering with more stronger cases.

Symptoms of Legionnaire’s disease can include high fever, muscle aches, headache, cough, and chills.
