The Solomon R. Guggenheim Museum appeared on the Health Department's 31-building UES Legionella remediation list published July 11 — but was among 19 buildings that had already completed disinfection. The museum never closed; city officials confirm no ongoing risk.

The Solomon R. Guggenheim Museum at 1071 Fifth Avenue — at the corner of East 89th Street in CB8 — appeared on the New York City Health Department's list of 31 Upper East Side buildings ordered to clean and disinfect their cooling towers, released July 11, in connection with the neighborhood's ongoing Legionnaires' disease cluster.

The Guggenheim was among 19 of the 31 buildings that had already completed remediation before the list went public. The museum employs an outside contractor that conducts monthly testing and treatment of its cooling tower — a routine the institution cited in a statement issued Saturday: "The city has confirmed that there is no additional action needed at this time, and this poses no risk to anyone inside the building." The museum did not close at any point during the outbreak.

Health officials cautioned that the preliminary positive results — PCR screenings — cannot distinguish between live and dead bacteria and do not identify any building as the source of the cluster. Culture tests, the definitive standard, take two weeks to return results.

The UES outbreak has reached more than 50 confirmed cases, with fewer than 20 people still hospitalized and no deaths reported as of July 11, according to the Health Department. [Colleague Mari Quinones has been tracking the wider outbreak on the City Power desk.]

The Frank Lloyd Wright–designed museum, a UNESCO World Heritage site, draws roughly one million visitors a year to the 89th Street block it has occupied since 1959.
