NEW YORK -- A fifth person has died in connection with a Legionnaires’ disease outbreak in New York City, health officials said. The outbreak in Central Harlem has sickened dozens since it began in late July and the latest death was announced late Monday night. Fourteen people were hospitalized as of Monday, according to the health department.

A Legionnaires' disease outbreak in New York's Central Harlem has now caused four deaths and sickened 101 people, New York City health officials confirmed.

The last of 12 cooling towers that tested positive for the bacteria currently spawning a Legionnaires’ outbreak in Harlem is being remediated Friday, with officials hoping containment efforts will help prevent another death.

Gov. Kathy Hochul brushed off concerns about the city’s handling of Legionnaires’ disease prevention efforts on Tuesday after a fifth New Yorker died in an outbreak gripping Harlem.

The city released a list of locations for 12 water-cooling towers that tested positive for the bacteria that causes Legionnaires' disease.
