Health Department Investigating Outbreak of Legionnaires' Disease in the South Bronx

The New York City Department of Health and Mental Hygiene is currently investigating an outbreak of Legionnaires' disease in the South Bronx. Thirty-one cases have been reported since July 10. There have also been two deaths reported in patients with Legionnaires' disease in these neighborhoods. The Health Department is actively investigating these deaths and their relationship to the outbreak. The Health Department is testing water from cooling towers and other potential sources in the area to determine the source of the outbreak. New Yorkers with respiratory symptoms, such as fever, cough, chills and muscle aches, are advised to promptly seek medical attention.

“We are concerned about this unusual increase in Legionnaires’ disease cases in the South Bronx,” says health commissioner Dr. Mary Bassett. “We are conducting a swift investigation to determine the source of the outbreak and prevent future cases. I urge anyone with symptoms to seek medical attention right away.”

Legionnaires' disease is caused by the bacteria Legionella. Additional symptoms include: headache, fatigue, loss of appetite, confusion and diarrhea. Symptoms usually appear two to 10 days after significant exposure to Legionella bacteria. Most cases of Legionnaires’ disease can be traced to plumbing systems where conditions are favorable for Legionella growth, such as whirlpool spas, hot tubs, humidifiers, hot water tanks, cooling towers, and evaporative condensers of large air-conditioning systems.

Legionnaires' disease cannot be spread from person to person. Groups at high risk for Legionnaire’s disease include people who are middle-aged or older – especially cigarette smokers – people with chronic lung disease or weakened immune systems and people who take medicines that weaken their immune systems (immunosuppressive drugs). Those with symptoms should call their doctor and ask about testing for Legionnaire’s disease.
