The New York Department of Health says it is investigating a community cluster of Legionnaires' disease in the South Bronx. One person has died and five others have been diagnosed as of Thursday evening.
According to officials, the cluster is in parts of Melrose and Morrisania, including ZIP codes 10451 and 10456.
The DOH says cooling towers in the area have been sampled and testing is underway.
Officials advise those who live, work in or have visited these areas since late August to contact a healthcare provider immediately if they develop flu-like symptoms. Legionnaires' is not contagious and can be treated with antibiotics.
According to the DOH, people age 50 and older, those who smoke or vape, those who suffer from chronic heart, lung, kidney or liver disease and people with weakened immune systems are at an increased risk of developing the disease.
This is the second cluster in NYC this summer - with 11 deaths and 94 cases reported in Manhattan's Upper East Side.
The DOH says it will conduct community outreach starting Friday, including holding town halls throughout the weekend, distributing information flyers and updating its website.
"Our disease investigators have confirmed five cases of Legionnaires' disease and are working quickly to identify and confirm any additional cases in the area. Sadly, one person has died, and our deepest condolences are with their loved ones," said NYC Health Commissioner Dr. Alister F. Martin. "I understand that New Yorkers may have heightened concerns following the recent Upper East Side cluster. We are taking immediate action. Water ecologists have sampled all cooling towers in the affected area. Any cooling tower that tests positive will be directed to undergo full cleaning and disinfection immediately. Community health workers will be canvassing the neighborhood. Anyone who lives, works, or has visited the affected area since late August and is experiencing flu-like symptoms should contact a health care provider as soon as possible."
