Increase of Legionnaires' Disease Cases in York County

Maine Center for Disease Control and Prevention is investigating an increase in cases of Legionnaires' disease, a potentially fatal pneumonia, in persons who live in, work in, or visit York County. Providers should consider the possibility of Legionnaires disease in patients presenting with respiratory illness, particularly if the patient reports spending time in York County in the 14 days prior to the onset of symptoms. Providers should perform testing using both urine antigen and sputum/respiratory culture and consider using empiric treatment with activity against Legionella.
