New York City is currently grappling with a major outbreak of Legionnaires’ disease that has resulted in at least five deaths and over 100 confirmed cases, all traced back to a series of cooling towers in Harlem. The outbreak, which began on July 26, 2025, has primarily affected several ZIP codes in upper Manhattan, including 10027, 10030, 10035, 10037, and 10039.

Legal action has been initiated against two construction companies, Rising Sun Construction and Skanska USA Building, accused of neglecting safety measures necessary to prevent this outbreak. Plaintiffs claim that the companies failed to maintain cooling towers, allowing untreated rainwater to create the ideal conditions for the growth of Legionella bacteria.

The outbreak has been described by attorneys involved in the lawsuits as “completely preventable.” Many plaintiffs are seeking compensation for medical expenses, lost wages, and pain related to their illnesses. Among the affected individuals is Duane Headley, a construction worker who became ill while working near Harlem Hospital and is still hospitalized. Another victim, electrician Nunzio Quinto, has reported severe symptoms and internal bleeding after potentially being exposed to the bacteria at a worksite.

Health officials have confirmed the presence of Legionella in 12 cooling towers across Central Harlem and have asserted that the disease is not transmitted from person to person. Symptoms of Legionnaires’ disease, which can escalate to pneumonia, include cough, fever, chills, muscle aches, and shortness of breath. This outbreak has been noted as the largest in a decade and takes place in an area historically marked by inadequate healthcare resources.

City officials are currently proposing stricter regulations to ensure better maintenance of cooling towers, aiming to mitigate future outbreaks. In light of the crisis, former Governor Andrew Cuomo and various mayoral candidates have criticized the city’s handling of health inspections, calling for independent reviews. The city’s Department of Health has confirmed that all affected cooling towers have been cleaned and disinfected; however, investigations will continue to ensure compliance with health codes.

Though health officials have indicated that the immediate risk of infection is currently low, residents are urged to remain observant for symptoms, particularly those over the age of 50 or with weakened immune systems. The city is taking steps to bolster health guidelines and prevention measures as the investigations unfold.

Background on Legionnaires’ Disease

Legionnaires’ disease is a form of pneumonia caused by the Legionella bacteria. It is typically contracted by inhaling mist or vapor contaminated with the bacteria, often found in man-made water systems such as cooling towers, hot tubs, and large plumbing systems. Prompt diagnosis and treatment are crucial, as the infection can become severe and even life-threatening, particularly for vulnerable populations.

Cooling Towers and Their Maintenance

Cooling towers are an essential part of many buildings, providing air conditioning through the evaporation of water. Without proper maintenance, including regular cleaning and disinfection, these structures can become breeding grounds for Legionella, posing significant health risks to both workers and residents in the surrounding areas.

Public Health Response

The outbreak has prompted increased scrutiny of the city’s public health policies and building regulations. Health officials are working diligently to inspect affected sites, ensure appropriate protocols are followed, and communicate risk factors to the public effectively.
