A recent Legionnaires' disease outbreak in Harlem that has claimed seven lives, and sickened 114 others, has been traced back to two city buildings including Harlem Hospital, according to health officials. The outbreak, which also resulted in 90 hospitalizations, has raised serious concerns about the oversight and maintenance of cooling towers used in air conditioning systems throughout the city. Cooling towers are a known breeding ground for the Legionella bacteria when not properly maintained, as reported by Gothamist.
In a shared announcement, city officials disclosed that genetic testing linked the bacteria from the hospital's and a construction site's cooling towers to the strain found in patients. Despite Harlem Hospital being compliant with the current Legionella testing regulations, submitting its most recent sample in June, it has once again become a focal point in an outbreak – repeating its involvement from an outbreak back in 2021, the New York Post reports.
Health Commissioner Michelle Morse highlighted the completion of full remediation and sanitization of both building's cooling towers and emphasized the development of comprehensive management programs to assure the health and safety of residents. Despite this assertion, available records seem to indicate a lack of such testing or city inspections at the construction site, a gap in oversight noted by Morse as something to be investigated further.
Reactions from former city officials spotlight the preventability of the outbreak. Chris Boyd, a former assistant commissioner for the health department, stated, "It only occurs in systems that are not managed properly." Meanwhile, former Gov. Andrew Cuomo, currently running for mayor, has called for an independent investigation into the city’s handling of the situation aiming, to ensure public trust and accountability, as per a statement obtained by Gothamist.
In response to the criticism and as part of its action plan, the health department is considering more stringent regulations. It proposed increasing the frequency of required tests for Legionella from every 90 days to every 30 days and plans to levy higher fines for non-compliance. Morse additionally spoke on the intent to hire more water ecologists to address staffing shortages, though specific budgetary provisions for these positions were not detailed. This follows a concerning trend reported by Gothamist that pointed out a significant reduction in the health department's cooling tower inspectors in recent years.
