The New York City Health Department is investigating a cluster of 18 cases of Legionnaires’ disease in the Upper East Side neighborhoods of Carnegie Hill and Yorkville. The city reports there have been no deaths associated with this cluster.

Legionnaires’ disease is a type of pneumonia. The risk to most people is low, but the city is urging people who live or work in these areas and have flu-like symptoms to visit a healthcare provider right away. Symptoms include fever, chills, muscle aches, cough, and shortness of breath.
