At least a quarter of the COVID-19 deaths in the United States were among nursing home residents, a new report said, a disclosure that came as coronavirus restrictions eased Monday even as U.S. protests against police brutality sparked fears of new outbreaks. The Florida Keys welcomed visitors for the first time in two months, the Colosseum opened its ancient doors in Rome, ferries restarted in Bangladesh and golfers played in Greece. But as tourist destinations worldwide reopened for business, new rules were in place to guard against the virus’ spread. Meanwhile, the scope of the devastation in the nation’s nursing homes became clearer in a report prepared for U.S. governors that said nearly 26,000 nursing home residents have died from COVID-19 — a number that is partial and likely to go higher. The data was based on reports received from about 80% of the nation’s 15,400 nursing homes as of May 24.
