Associated Press: A nursing assistant who worked while sick likely brought the coronavirus into an Iowa nursing home where 15 residents later died, according to a new state inspection report. The employee was allowed to keep working because the Crystal Heights Care Center in Oskaloosa failed to adequately screen staff for symptoms at the beginning of their shifts, inspectors wrote. Rather than have an employee take temperatures and ask health questions, those arriving were “permitted to self-screen” without independent monitoring, their investigation found.
