Legionnaires' disease cluster grows in New York City
There are 36 confirmed cases of Legionnaires' disease tied to an outbreak on the Upper East Side.
22 people who are hospitalized are among the cases in the outbreak.
The health department believes the outbreak is being spread by contaminated mists from cooling towers.
“We're going to be taking the step of releasing the addresses of wherever has been impacted, because we know that transparency is also a critical part of how New Yorkers can continue to go about their day,”
