1 dead, multiple people sickened in Legionnaires' disease cluster in New York City
The New York City Department of Health said July 30 that it is investigating the cluster, which has left one dead and 22 others sick in Central Harlem.
Legionnaires' disease is a severe pneumonia caused by a type of bacteria called Legionella, according to the CDC.
The risk to most people is low, and the disease is not contagious, the agency said. Some people, including those older than 50, smokers or those with a weakened immune system, are at higher risk for the disease, according to NYC Health.
NYC Health said it believes the source of the bacteria causing this cluster is a cooling tower in the area. Here's what to know.
Where is NYC Legionnaires' cluster?
The Legionnaires' disease cluster is in Central Harlem. According to NYC Health, the following zip codes are affected:
10027
10030
10035
10037
10039
People who live or work around these ZIP codes and develop flu-like symptoms should see a health care provider right away, the agency said.
What caused NYC Legionnaires' cluster? Is water safe to drink?
NYC Health said the likely source of the bacteria causing the Legionnaires' cluster is a cooling tower in the area.
Cooling towers, which are water systems typically found on the top of buildings, spray mist that can contain the bacteria that causes Legionnaires' disease, the agency said.
All of the cooling towers in the affected area are being tested for the bacteria, the health department said.
The health department also said the cluster does not involve any building's plumbing system, meaning it is safe to drink water, bathe, shower, cook and use air conditioners.
What is Legionnaires' disease?
Legionnaires' disease is a type of pneumonia caused by consuming water or mist contaminated with Legionella bacteria, according to the CDC. Symptoms of the disease, which can take up to 14 days after exposure to show up, include:
Cough
Fever
Headaches
Muscle aches
Shortness of breath
The disease can be treated with antibiotics, and most healthy people who get infected usually get better, but complications are possible. About 1 in 10 people who get Legionnaires' disease die from it, according to the CDC.
How to stay safe from Legionnaires' disease
Legionnaires' disease is a waterborne illness, so the CDC recommends cleaning pipes and devices that use water to remove germs and debris.
Prevention methods include flushing showerheads and faucets that haven't been used recently, and regularly cleaning devices that use water, per the CDC.
Owners of cooling towers, decorative fountains and hot tubs should follow manufacturer instructions for cleaning, disinfecting and maintenance, the CDC said.

Legionnaires' outbreak grows: What are the disease's first symptoms?
(NEXSTAR) – Three people have died and at least 67 have been infected as a cluster of Legionnaires' disease cases in New York City continues to spread. The case count has ballooned since the bacteria that causes Legionnaires' started sickening people in late July. City health officials link the outbreak in Central Harlem to cooling towers, structures containing water and a fan that are used to cool buildings. They said 11 of these towers initially tested positive for a type of bacteria that causes Legionnaires', but the problem has been fixed. Three dead as Legionnaires' cluster spreads in NYC Legionnaires' disease is a type of pneumonia caused by bacteria that grows in warm water. It can spread through water systems, like showerheads, hot tubs or cooling towers for central AC. People often get the disease by inhaling mist from contaminated water, but it is not spread from person to person. What are the symptoms of Legionnaires' disease? Once exposed to the bacteria, symptoms can take anywhere from two days to two weeks to show up, according to the Centers for Disease Control and Prevention. The symptoms of Legionnaires' overlap with other pneumonia symptoms: cough, fever, headaches, muscle aches and shortness of breath. In the most serious cases, Legionnaires' can cause lung failure or death. The pneumonia can be confirmed with a chest X-ray, but a lab test of a patient's urine or phlegm would be able to confirm if the pneumonia is caused by Legionella bacteria. Most people exposed to the bacteria don't get sick, the CDC notes, but those with pre-existing conditions can suffer serious symptoms or death. About 1 in 10 people who gets the disease will die due to complications, the CDC says. What is the treatment for Legionnaires' disease? Those in the neighborhoods of New York City impacted by the outbreak (ZIP codes 10027, 10030, 10035, 10037, 10039 and surrounding areas) should contact their doctor if they have any of the symptoms described above. That's especially true for people 50 and older, people who smoke and people with chronic lung conditions, as they are more susceptible to serious consequences. Once identified, the disease can be treated with antibiotics.

Death toll from New York Legionnaires' disease outbreak rises to 3
A Legionnaires' disease outbreak in New York City has infected 67 people and caused three deaths. File Photo by Shou Sheng/EPA A Legionnaires' disease outbreak in New York City has infected 67 people and caused three deaths, health officials say. The cases have been reported in Central Harlem. Officials believe the source of the outbreak is cooling towers on nearby buildings, according to the New York City Department of Health and Mental Hygiene. Cooling towers are large rooftop devices that release mist into the air to help cool buildings. But if the water inside the tower becomes too warm or isn't disinfected properly, bacteria called Legionella can grow. People can get sick when they inhale this contaminated mist. The disease does not spread from person to person. The city announced the outbreak on July 25. Since then, 11 cooling towers in the area tested positive for Legionella pneumophila, a strain of the bacteria. Those towers have now been remediated, the officials said. "Anyone in these Zip codes with flu-like symptoms should contact a health care provider as soon as possible," Acting Health Commissioner Dr. Michelle Morse said in a news release. Legionnaires' disease is a type of pneumonia, the U.S. Centers for Disease Control and Prevention says. Symptoms can include: Cough, fever, headaches, muscles aches and shortness of breath. The infection can be treated with antibiotics. Left untreated, it may lead to serious complications like lung failure or death, the CDC explains. Each year, around 6,000 cases are reported in the United States, the Occupational Safety and Health Administration says. But health officials suspect the true number is higher, because it can be hard to tell Legionnaires' apart from other types of pneumonia.
