NEW YORK (AP) — A Legionnaires’ disease outbreak in a New York City neighborhood now counts 60 cases, but new diagnoses are slowing, health officials said Tuesday. They reported progress on inspections for the disease-causing bacteria but still haven’t pinpointed a source.No one has died in the outbreak on Manhattan’s Upper East Side, but 49 patients have required hospitalization, though 34 so far have gone home, city Health Commissioner Dr. Alister Martin said. City data show two new cases were diagnosed from samples taken Thursday through Saturday, compared to as many as 11 per day from earlier samples. “All of these things together paint an encouraging sign,” Martin said at a virtual news briefing.It came a day after City Council Speaker Julie Menin, a Democrat and Upper East Side resident, complained that the Health Department wasn’t doing and disclosing enough. A message seeking comment was sent Tuesday to Menin’s office. Legionnaires’ disease is a form of pneumonia caused by Legionella bacteria, which grow in warm water and can spread in building cooling systems, hot tubs and showerheads. In many cases, people contract the disease by inhaling tiny droplets of contaminated water; Legionnaire’s doesn’t spread person-to-person.
