Legionnaires’ disease outbreak kills one and infects others in the South Bronx

The disease is a form of pneumonia caused by Legionella bacteria, which can grow in warm water and spread through mist produced by cooling towers

One person has died from legionnaires' disease, and four more have been sickened in New York City amid a new cluster of cases only weeks after local health officials had declared a separate deadly Manhattan outbreak of the illness over.

On Thursday, New York City officials announced that their municipal health department launched an investigation into a community cluster in parts of Melrose and Morrisania in the South Bronx, including ZIP codes 10451 and 10456.
