Health officials in New York City have reported an uptick in cases of Legionnaires’ disease in Harlem, now totaling eight confirmed cases, up from three reported just days earlier. While there have been no fatalities linked to this outbreak, the city’s Department of Health is urging residents, particularly those living in affected areas, to remain alert for flu-like symptoms.
Legionnaires’ disease, a severe form of pneumonia, occurs when individuals inhale water vapor contaminated with Legionella bacteria. The affected ZIP codes include 10027, 10030, 10035, and 10037. To combat this cluster, health department officials are inspecting cooling towers in the neighborhood, which play a significant role in the spread of the bacteria, and are conducting water tests.
Dr. Celia Quinn, the deputy commissioner of the Division of Disease Control, emphasized that these outbreaks often correlate with the presence of Legionella in cooling towers—large metal units utilized for central air conditioning in substantial buildings. She noted that humid and hot weather can exacerbate the growth of the bacteria, but reassured the public that typical window air conditioning units are not a cause for concern.
For those impacted, symptoms of Legionnaires’ disease can manifest between 2 to 14 days following exposure and may include fever, cough, muscle aches, shortness of breath, nausea, confusion, and diarrhea. Fortunately, the infection can be treated effectively with antibiotics if diagnosed early, and the majority of healthy individuals exposed to the bacteria do not fall ill.
Historically, Legionnaires’ disease cases in the United States have risen over the last two decades, peaking in 2018. Although serious, particularly for older adults or those with compromised immune systems, the city typically sees between 200 to 700 cases annually, most of which are isolated incidents. In light of a significant outbreak in 2015 that resulted in multiple deaths, continuous monitoring has become a priority for health officials.
Authorities advise anyone residing in the affected areas experiencing potential symptoms to ensure prompt medical consultation. With heightened awareness and vigilance, city officials believe they can manage this growing situation effectively.
