Overview
- Ats Città Metropolitana di Milano is managing a suspected cluster concentrated near via Rembrandt, with patients living in multiple buildings across roughly one square kilometre.
- An 89-year-old man died on November 3, six people remain hospitalized in the ASST Santi network, and a patient at Ospedale Sacco has been discharged.
- Investigators are collecting household water samples and reviewing sensitive neighborhood sites such as cooling towers, fountains and air‑conditioning systems, with laboratory results still pending.
- Authorities say those infected had predisposing risk factors, and transmission occurs through inhaling contaminated water aerosol rather than person to person or by drinking tap water.
- Residents report scarce information as Codacons files a complaint with prosecutors and urges expanded checks, transparent reporting and wider monitoring of older building systems.
