One person died in an outbreak of Legionnaires’ disease on Manhattan’s Upper East Side, city health authorities said Friday.
The outbreak, detected earlier this month, has infected 67 people. Officials said the number of new cases declined over the past week. This was the first reported death.
Health authorities did not identify the person who died or provide additional details.
“I am saddened to report that one person has died in connection with the Legionnaires’ disease community cluster on the Upper East Side,” city Health Commissioner Dr. Alister F. Martin said in a statement. “My deepest condolences are with their loved ones.”
Legionnaires’ disease is a severe form of pneumonia caused by bacteria that can grow in warm, stagnant water. In New York City, outbreaks have at times been linked to rooftop cooling towers used in air conditioning and refrigeration systems. Water vapor from those systems can carry Legionella bacteria, which can then be inhaled by people nearby.
The illness can cause severe pneumonia, especially in older adults and people with certain chronic health conditions. Symptoms can include high fever, cough, headache, chest pain, and altered mental status.
In recent weeks, health authorities tested cooling towers in several Upper East Side ZIP codes to find possible sources of the outbreak. Officials said more testing was needed to determine the source. In the meantime, dozens of property owners were ordered to drain and disinfect their cooling towers.
Officials said there were signs the outbreak may be nearing its end. In early July, about five to 10 new cases were diagnosed each day. That fell to about one a day.
Most of the 67 people sickened were hospitalized and later discharged. As of Thursday night, 12 patients remained hospitalized, according to health authorities.
