New York City health officials detected traces of Legionella bacteria in a cooling tower at Yankee Stadium while investigating a South Bronx cluster of Legionnaires’ disease. Officials stressed that no current illness has been linked to the stadium.
Ten people in the South Bronx have developed Legionnaires’ disease, one person has died and three remained hospitalized at the time of the latest report. The Yankee Stadium tower was one of 10 cooling towers in the area that tested positive for bacterial material.
The Yankees said the stadium’s cooling system is tested regularly and that its own recent results did not detect Legionella. City officials ordered owners of affected towers to clean and disinfect their systems.
How Legionnaires’ disease spreads
Legionnaires’ disease is a serious form of pneumonia caused by breathing small water droplets containing Legionella. Cooling towers, large plumbing systems, hot tubs and decorative fountains can become sources when water systems are not properly maintained.
The illness does not normally spread from person to person. Older adults, smokers and people with chronic lung disease or weakened immune systems face a higher risk of becoming seriously ill.
Detection does not prove transmission
A preliminary positive result in a cooling tower does not automatically establish that it caused an outbreak. Officials must compare environmental samples with clinical evidence and determine whether live bacteria are present. That additional testing may take up to two weeks.
No health directive required the postponement of games, according to the Yankees. People who recently spent time in the affected area and develop fever, cough, shortness of breath or muscle aches should contact a healthcare professional, particularly if they are in a higher-risk group.
Confirmed: Legionella material was detected and a South Bronx illness cluster is under investigation. Not confirmed: Yankee Stadium has not been identified as the source of any case.
