Developing Story Note: This report covers new developments involving a Legionnaires’ disease<\/a> cluster in the South Bronx. Information may change as the NYC Health Department releases additional findings. Latest verified update: the department’s announcement on the evening of Thursday, Sept. 10, 2026, with case figures current as of that announcement.<\/p>\n

New York City health officials are investigating a likely community cluster of Legionnaires’ disease in the South Bronx after five people were diagnosed and one person died, the city announced Thursday evening. The cluster covers parts of Melrose and Morrisania in ZIP codes 10451 and 10456, and results for other possible cases are pending, ABC7 New York reported<\/a>.<\/p>\n

The city is urging anyone who lives or works in the area, or who has visited since late August, to contact a health care provider right away if they develop flu-like symptoms such as fever, cough or difficulty breathing. Legionnaires’ disease is a type of pneumonia that is not contagious from person to person and can be treated with antibiotics when caught early.<\/p>\n

The announcement lands in a city still absorbing its last outbreak. This is New York’s second community cluster of 2026, following the Upper East Side cluster that the city says reached 94 cases and 11 deaths<\/a> before its investigation concluded.<\/p>\n

Cooling Tower Testing Begins in Melrose and Morrisania<\/p>\n

“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,” NYC Health Commissioner Dr. Alister F. Martin said, as reported by PIX11<\/a>.<\/p>\n

Martin said water ecologists have sampled every cooling tower in the affected area, and any tower that tests positive will be ordered to undergo full cleaning and disinfection immediately. Community health workers are canvassing the neighborhood to reach residents directly.<\/p>\n

Here is what is confirmed so far. Five cases have been diagnosed, and one person has died. The two ZIP codes have been identified, and cooling tower samples are being tested at the Health Department’s Public Health Laboratory. The source of the bacteria has not been identified, and no building has been named.<\/p>\n

The Bronx has been here before. In 2022, the city investigated a cluster in Highbridge and bordering areas, including ZIP code 10456, that grew to 24 cases and two deaths<\/a> within a month. A much larger 2015 South Bronx outbreak led the city to require cooling tower registration and routine Legionella testing.<\/p>\n

Who Faces the Highest Risk in the South Bronx<\/p>\n

Most people exposed to Legionella bacteria do not get sick. According to the NYC Health Department, the risk is higher for adults 50 and older, people who smoke or vape, people with chronic heart, lung, kidney or liver disease or diabetes, and anyone with a weakened immune system.<\/p>\n

Symptoms include fever, chills, muscle aches, and cough, and some people also develop headache, fatigue, loss of appetite, confusion, or diarrhea. The city says it is especially important for people at higher risk to seek care right away and to tell their provider they are worried about Legionnaires’ disease.<\/p>\n

Residents can continue normal daily routines, including showering and using window air conditioners. The Health Department says people cannot get Legionnaires’ disease from drinking tap water, cooking or using air conditioning. Community clusters typically spread through mist from building cooling towers, which is why testing focuses on rooftop systems.<\/p>\n

For families, the practical concern is older relatives and neighbors. Melrose and Morrisania include many multigenerational households, and the people most at risk may be least likely to seek care quickly for what feels like a bad cold.<\/p>\n

Accountability Questions After Two Clusters in One Summer<\/p>\n

Some residents told ABC7 they were not confident in the city’s response. “Not really… because the way they handled it in the past, you know what I mean?” resident Charles Laloma said.<\/p>\n

The new cluster comes days after the city announced reforms following the Upper East Side outbreak. MedicalDaily reported that New York will build a public map of every cooling tower<\/a> with inspection histories and speed up enforcement hearings, though the map is not expected until spring 2027.<\/p>\n

Residents do not have to wait for that tool. The city already lets anyone look up cooling tower inspection results<\/a> by building address.<\/p>\n

What remains unknown is the source of the bacteria, whether more cases will be confirmed, and when laboratory results on the tower samples will be released. Because symptoms can take days to appear after exposure, new diagnoses in the coming days would not necessarily mean exposure is continuing.<\/p>\n

Steps Residents Can Take While the Source Is Unknown<\/p>\n

Anyone in the affected area since late August who develops fever, cough, chills, muscle aches, or trouble breathing should contact a provider promptly and mention where they live, work, or spent time. Legionnaires’ disease cannot be told apart from other pneumonias by symptoms alone, so asking whether Legionella testing is appropriate can speed diagnosis.<\/p>\n

Severe shortness of breath, chest pain, confusion, or rapidly worsening illness requires emergency care. People without a regular doctor can call 311 for information about where to go. Those who are already sick should not wait for the cluster’s source to be confirmed before getting checked, because early antibiotic treatment improves the chance of a good recovery.<\/p>\n

Building owners in the two ZIP codes should confirm their cooling towers are registered and that required sampling is current. Any tower that tests positive will be ordered to clean and disinfect immediately.<\/p>\n

MedicalDaily will update this report as the Health Department releases new case counts and cooling tower results. For now, the most reasonable step is symptom awareness, especially for older adults and people with chronic illness, rather than avoiding the neighborhood.<\/p>\n

Key Questions Answered<\/p>\n

Where is the Bronx Legionnaires’ cluster?<\/p>\n

The cluster covers parts of Melrose and Morrisania in the South Bronx, including ZIP codes 10451 and 10456.<\/p>\n

How many people are sick?<\/p>\n

Five people have been diagnosed and one has died, according to the NYC Health Department’s Sept. 10 announcement. Results for other possible cases are pending.<\/p>\n

Who should seek medical care?<\/p>\n

Anyone who lives or works in the area, or visited since late August, and develops fever, cough, chills, muscle aches or trouble breathing should contact a provider promptly.<\/p>\n

Is Legionnaires’ disease contagious?<\/p>\n

No. It does not spread from person to person. People get sick by breathing in water mist that contains Legionella bacteria.<\/p>\n

Is tap water or air conditioning safe?<\/p>\n

Yes. The Health Department says people cannot get Legionnaires’ disease from drinking water, cooking or using air conditioning.<\/p>\n

Who is most at risk?<\/p>\n

Adults 50 and older, people who smoke or vape, people with chronic heart, lung, kidney, or liver disease or diabetes, and people with weakened immune systems.<\/p>\n

What is the city doing?<\/p>\n

Water ecologists sampled all cooling towers in the area; positive towers will be ordered to disinfect, and community health workers are canvassing the neighborhood.<\/p>\n","protected":false},"excerpt":{"rendered":"Developing Story Note: This report covers new developments involving a Legionnaires’ disease cluster in the South Bronx.
