HARRISBURG (AP) – The Wolf Administration is backing off its demand that nursing homes in the state test all residents and staff for COVID-19 on a weekly basis. It instead ordered them to complete a single baseline test. Last month, Wolf had vowed that weekly testing would start June 1. He said his administration had a plan in place to accomplish it. Health experts were skeptical and cited logistical, operational, and financial hurdles. The state Health Secretary also ordered nursing homes and other facilities that care for older adults to test all residents and staff “at least once” by July 24.
