Overview
- The city first identified a localized Legionnaires’ cluster on July 2 and the case count has since risen to roughly 54–56 people, with fewer than 20 currently hospitalized and no confirmed deaths.
- Health teams PCR‑screened about 180–183 rooftop cooling towers in ZIP codes 10028, 10128 and 10075 and found Legionella genetic material in 31 towers, prompting the release of a preliminary list of addresses.
- Owners of 19 PCR‑positive towers have reported completed cleaning and disinfection, and the remaining 12 towers were ordered to finish remediation by the weekend.
- Officials emphasize that PCR detects DNA only and cannot prove live, infectious bacteria; the city is conducting culture tests and plans whole‑genome sequencing to identify live Legionella and try to match strains to patients.
- Public guidance stresses that exposure comes from outdoor cooling‑tower mist rather than indoor plumbing, residents who were in the area since late June with fever, cough or shortness of breath should see a doctor, and investigators are reviewing tower maintenance and testing records for compliance gaps.
