The city Department of Health on Monday confirmed they are investigating seven new cases of Legionnaires' disease in the Morris Park section of the Bronx.
According to a press release, the DOH says they were notified of the new cases between September 21 and September 27.
The DOH says they are working to identify a potential source.
Health officials say the cluster is unrelated to the outbreak in the South Bronx over the summer that was later linked to bacteria found in the cooling tower of the Opera House Hotel.
The DOH says patients in this latest cluster live or work in the Morris Park neighborhood, range in age from 45 to 75 and are all currently hospitalized.
There have been no deaths.
Since Saturday, scientists have taken samples from all local cooling towers.
"These are all towers that have previously been cleaned as a result of the commissioner's order and obviously the new legislation. So we're going back and checking them again even though they were cleaned quite recently," said Mayor Bill de Blasio.
"All of them are connected to a neighborhood in the eastern section of the Bronx, which is called Morris Park. Three of the individuals live there. Four have other connections, work or have been there," said Health Commissioner Dr. Mary Bassett. "Because we indentify this as a cluster doesn't mean that we know what the cause is of these infections."
In a statement, Bassett urged residents with respiratory symptoms such as fever, cough, chills and difficulty breathing to seek medical attention and says the department is "taking immediate steps to determine the source and protect the people who live and work in Morris Park."
She says the department is taking immediate steps to determine the source and protect the people who live and work in Morris Park.
