Two Dead in South Bronx Legionnaires Cluster

Health officials have disinfected cooling towers that screened positive as culture tests continue to determine whether live bacteria at specific sites caused the illnesses.

Overview

  • Health Commissioner Dr. Alister Martin confirmed late Thursday that a second person has died and that there are at least 13 to 14 confirmed cases tied to parts of Melrose and Morrisania in ZIP codes 10451 and 10456.
  • City teams tested about 24 cooling towers and found Legionella DNA in 10 on preliminary PCR screens, and those 10 towers have been drained, cleaned and disinfected by city order.
  • Culture testing is now under way to see if live Legionella were present when samples were taken and to link any tower to the illnesses; that process can take up to two weeks and will determine next investigative steps.
  • Officials have stepped up outreach and inspections, holding a town hall, canvassing neighborhoods, distributing thousands of pamphlets and urging anyone with flu-like symptoms who lives in or visited the zip codes to seek medical care immediately.
  • The cluster follows a larger Upper East Side outbreak earlier this summer and revives local concerns about enforcement, private-owner maintenance of cooling systems, and higher vulnerability in the South Bronx because of underlying health disparities.
