What is Legionnaire's Disease?
Legionnaire's Disease is a bacterial disease that causes a severe, sometimes life-threatening, pneumonia.

Who can get Legionnaire's Disease?
Disease occurs most frequently in older individuals, with most cases diagnosed in persons at least 50 years of age.   People prone to infection include smokers, those with suppressed immune systems, and those who have chronic illnesses such as diabetes, kidney disease, and lung disease.

How is it treated?
Legionnaire Disease can be life threatening and often requires hospitalization, so seek medical attention immediately if you suspect you may be infected. Antibiotics may be required.
