The number of cases of Legionnaires’ disease on the Upper East Side has climbed to 14, and health officials are currently investigating the origin of the outbreak.
As of Sunday, patients in the Carnegie Hill and Yorkville areas have been diagnosed with this potentially severe pneumonia-like condition, according to the New York City Department of Health.
This figure has surged from just two cases reported by the health department last Thursday when they first identified the illness at a Manhattan location.
Residents and visitors in the 10028, 10128, and 10075 ZIP codes who have experienced flu-like symptoms, such as fever or coughing, since late June are urged to reach out to their healthcare providers.
If left untreated, Legionnaires’ disease can be serious. Fortunately, it’s not contagious and is typically treatable with antibiotics.
“Legionellosis can be fatal, but it can be effectively managed if caught early,” stated Dr. Alistair Martin, New York City Health Commissioner.
He also noted that specific groups, including anyone over 50 or those with chronic health conditions, should be particularly vigilant about their symptoms and seek medical advice promptly.
Health officials suspect that a cooling tower in the vicinity is responsible for the outbreak, though the exact source remains unidentified. These towers, often located on rooftops, can disperse a mist carrying Legionella bacteria, leading to pneumonia.
Authorities have initiated investigations to pinpoint the source and will conduct testing on all cooling towers in the area.
Despite the rising cases, the health department reassured that the general risk to the public is still low. Residents can safely continue regular activities like bathing and using air conditioning, especially following the extreme heat wave recently experienced in the city.
Last summer, a Legionnaires’ outbreak in Harlem resulted in 114 illnesses, with 90 hospitalizations and seven fatalities.
Previous claims from Pastor Al Sharpton and attorney Ben Crump suggested that nearly 20 people may have died due to misdiagnosis during that outbreak, significantly higher than the official count.
In response to such events, the City Council passed legislation last fall mandating monthly Legionella testing for building owners during the warmer months when cooling towers are in operation.
As of now, there have been no reported deaths linked to the current Legionnaires’ outbreak, according to health officials.
