One person has died in connection with a cluster of Legionnaires’ disease cases in New York City, Health Commissioner Dr. Alister Martin said Friday.

As of Thursday night, 67 cases have been reported, and 12 people are hospitalized. Forty-three others were previously hospitalized but have been discharged.

Martin said officials will not be releasing any further information on the person who died.

Officials believe that the cases are connected with bacteria found in building cooling towers on the Upper East Side. Towers for 76 buildings tested positive for Legionella bacteria, and their owners were ordered to drain, clean and disinfect them.

“All have confirmed that they completed the required remediation,” Martin said in a statement.
