- At least nine people have been diagnosed with Legionnaires' disease in the cluster, including one death and three hospitalizations.
- Investigators ordered the 10 cooling towers to be drained, cleaned and disinfected after the preliminary tests detected Legionella DNA.
- The health department cautioned that PCR testing detects Legionella DNA but cannot determine if bacteria are alive and thus cannot confirm a tower as the source; only live Legionella can cause illness.
- The department said eight of the cooling towers have complied with the 31-day testing requirement.
- Legionnaires' disease killed 1 person and infected five others in the South Bronx, the city Health Department announced.
- The 10 addresses identified for full investigation are: 820 Concourse Village West; 234 E. 149th St.; 1 E. 161st St.; 470 E. 161st St.; 1265 Franklin Ave.; 567 Melrose Ave.; 3339 Park Ave.; 1160 Teller Ave.; 890 Washington Ave.; 1085 Washington Ave.
- Cases were reported in the Morrisania and Melrose neighborhoods.
- Health Commissioner Dr. Alister F. Martin said investigators have confirmed five cases and are working to identify and confirm additional cases.
New York City health officials have detected Legionella DNA at 10 cooling towers in the South Bronx, including the tower that serves Yankee Stadium, and have ordered those towers drained, cleaned and disinfected while investigators probe a local Legionnaires’ cluster.
The preliminary finding came from PCR testing, which the New York City Health Department emphasized detects bacterial DNA but cannot determine whether bacteria are alive — only live Legionella can cause illness.
City investigators tied the detection to a cluster that has diagnosed at least nine people with Legionnaires’ disease; the department reported one death and three hospitalizations among those cases. The department identified the 10 sites by address for full investigation: 820 Concourse Village West; 234 E. 149th St.; 1 E. 161st St.; 470 E.
161st St.; 1265 Franklin Ave.; 567 Melrose Ave.; 3339 Park Ave.; 1160 Teller Ave.; 890 Washington Ave.; and 1085 Washington Ave. Eight of those towers have complied with the 31-day testing requirement, the department said, while officials ordered remediation measures for all 10 after the preliminary tests.
Health officials are treating the PCR results as a trigger for immediate cleaning and disinfection—draining and disinfecting cooling towers is the department’s standard public-health response when preliminary tests detect Legionella DNA.
The reporting stresses the distinction between DNA detection and confirmation of live bacteria as the source: PCR can flag contamination but cannot on its own confirm which facility caused human infections.
For residents and visitors in the affected Bronx blocks, the immediate implication is mandatory remediation at the named addresses while health investigators continue epidemiologic work to link environmental findings to patient infections.
