Despite Trump administration efforts to erect a protective shield around nursing homes, coronavirus cases are surging within facilities in states hard hit by the latest onslaught of COVID-19. An analysis of federal data from 20 states for The AP finds that new weekly cases among residents rose nearly four-fold from the end of May to late October, from 1,083 to 4,274. Resident deaths more than doubled, from 318 a week to 699, according to the study by University of Chicago health researchers Rebecca Gorges and Tamara Konetzka. Equally concerning, weekly cases among nursing home staff in surge states more than quadrupled, from 855 the week ending May 31, to 4,050 the week ending Oct. 25. That rings alarms because infected staffers not yet showing symptoms are seen as the most likely way the virus gets into facilities.
