A seventh individual has died following a diagnosis of Legionnaires' disease, marking a somber milestone in the ongoing public health investigation on the Upper East Side. According to the city's health department, the total number of confirmed cases has reached 92.

Health Commissioner Dr. Alister Martin confirmed the latest fatality, expressing condolences to the families affected by the outbreak. While the situation remains serious, officials noted that 67 of the patients who required hospitalization have since been discharged, with only five individuals currently remaining under medical care.

The outbreak, which is the second of its kind in Manhattan within the last two years, has been traced to contaminated cooling towers. In response to the cluster of illnesses, city investigators identified 56 cooling towers that tested positive for *Legionella* bacteria. All identified units have since undergone inspection.

Despite the rising death toll, there are signs that the immediate threat may be subsiding. The city reported that no new cases of the disease have been documented in the past two weeks, leading officials to conclude that the source of the exposure has likely been eliminated.

Looking ahead, the city has indicated that further information regarding enforcement actions against cooling tower operators will be released in the coming days. The health department continues to monitor the situation to ensure compliance with safety standards and to prevent further transmission.
