Legionnaires’ Disease

 

In July 2015, New York City experienced an outbreak of Legionnaires’ disease in the Bronx. An investigation was launched and on August 20, 2015, a cooling tower at a local hotel was confirmed as a source of the outbreak. Legionnaires’ disease (or Legionellosis) is a type of pneumonia. It is caused by bacteria (Legionella) that grow in warm water. Most people exposed to the bacteria do not become ill but to some, Legionnaires’ disease can be deadly.

The 2015 outbreak prompted Governor Cuomo and New York State Health Commissioner Dr. Howard Zucker to issue preventive regulations to keep the public safe from Legionnaires’ disease, a potentially deadly disease. More information about the regulations, Legionnaires’ disease and cooling towers can be found on these links.
