A recent outbreak of legionnaires’ disease in Manhattan has sickened at least 28 individuals, with health officials attributing the rise in cases to worsening climate conditions. On the Upper East Side, New York City health department officials are actively sampling water from nearly 160 building cooling towers to identify sources of the bacteria.
Climate Change and Legionnaires’ Disease
Dr. Alister Martin, the commissioner of the New York City health department, stated, “This is now a subtropical climate. It is absolutely true that climate change is worsening our exposure and increasing the propensity for legionnaires’ disease clusters like we’re seeing today.”
The Legionella pneumophila bacterium typically thrives in warm water environments. While it is often harmless, inhalation of contaminated water vapor can lead to severe pneumonia. Symptoms include cough, fever, headaches, muscle aches, and shortness of breath. Although the disease affects fewer than three people per 100,000, it has a mortality rate of about 10% among diagnosed cases.
Investigation and Response Measures
To combat the outbreak, health officials have ordered at least 19 buildings to drain, clean, and disinfect their cooling towers, which are critical to large buildings’ heating and cooling systems. These buildings are considered “of interest” as officials continue their investigation to determine the outbreak's origin.
“You’re walking down the street minding your own business, breathing in the air, and the air may be contaminated from a cooling tower you can’t even see,” said George Yates, a Harlem resident who contracted the disease in a previous outbreak.
Disparities in Impact
While the current outbreak is concentrated in affluent zip codes, past studies have shown that legionnaires’ disease disproportionately affects poorer communities and Black Americans. Community leaders have expressed frustration over these disparities. “I started to believe that Legionella only knew Black and brown neighborhoods,” said Marquis Harrison, chair of a Manhattan community board.
The health department is working diligently to identify the sources, but it may take up to a month to finalize the investigation, as testing and analysis of water samples are ongoing. In many cases, the CDC notes, the source of legionnaires’ outbreaks remains unidentified.
- 28 people have been sickened
- 19 buildings ordered to clean cooling towers
- 10% mortality rate among diagnosed cases
As climate change continues to create favorable conditions for Legionella, the city faces ongoing challenges in managing outbreaks effectively.
