One person is dead from Legionnaires' disease and two remain hospitalized after a cluster of outbreaks on the Levittown/Wantagh border, a Nassau health department official said Thursday.

Seven more people were hospitalized but have been discharged, the official said. Nassau health officials are investigating all 10 cases in the cluster, which spans a one-mile radius of Wantagh Avenue and Old Jerusalem Road, according to a county health department news release.

The disease is caused by a type of bacteria called Legionella. People can get Legionnaires’ disease, a form of pneumonia, when breathing in a mist or vapor containing the bacteria, most commonly from cooling towers, fountains, spray parks, hot tubs, whirlpool spas, showers and faucets, the release said.

State health department officials said the cases in 2021 are in line with past years.

"The New York State Department of Health is providing technical assistance and guidance to the Nassau County Department of Health during their investigation of ten Legionella cases," said department spokesperson Sam Fuld in a statement Thursday night. "The numbers for 2021 are consistent with numbers we have seen in previous years as there are typically between 350 and 800 cases diagnosed annually in New York State. It’s important for New Yorkers to know Legionella is not spread person-to-person."

The Legionella bacteria are found naturally in the environment and transmitted by aerosolized water.

The bacteria are not spread from person to person, department officials emphasized.

Signs of Legionnaires’ disease may include cough, shortness of breath, high fever, muscle aches, and headaches. These symptoms usually begin 2 to 10 days after exposure to the bacteria. The disease requires treatment with antibiotics and most cases are treated successfully, the release said.

People at higher risk of becoming ill with Legionnaires’ disease are those 50 years of age or older, current or former smokers, those with chronic lung disease, those with a weakened immune system, and people who take immunosuppressant medications.

In June, the Centers for Disease Control and Prevention reported that Legionnaires’ disease has been on a rapid rise in the United States for the past decade.

New York State is experiencing a statewide increase in cases of the disease, officials have said.

Last month, the New York City Health Department officials said they had closed an investigation into a cluster of 18 Legionnaires' cases in Harlem. All 18 people were hospitalized but none died, the department said in a statement on its website.

Laboratory analyses "showed that the bacteria from one of the clinical specimens matched a cooling tower at NYC Health + Hospitals/Harlem," the statement said.

Residents who have symptoms consistent with Legionnaires’ disease are encouraged to contact their health care provider.
