Nursing home residents account for nearly 1 in 10 of all the coronavirus cases in the United States and more than a quarter of the deaths, according to an AP analysis of government data released Thursday. … About 1.4 million older and medically frail people live in such facilities, a tiny share of the American population that has borne a crushing burden from the pandemic. Most residents have been in lockdown since early March, isolated from families and friends, even in death. AP’s analysis of data from the Centers for Medicare and Medicaid Services found that nearly half of the more than 15,000 nursing homes have reported suspected or confirmed cases of COVID-19 as of June 7. About 1 in 5 facilities — or 21% — have reported deaths.
