BERLIN—On a continent still struggling with high Covid-19 rates, one small Alpine country is trying something new to reopen its schools: Require that students test themselves twice a week before they can attend class.
The experiment could bear valuable lessons for the U.S., where many schools remain closed, especially because it is happening in a place with relatively high infection rates despite months of restrictions.
The U.S. Centers for Disease Control and Prevention last week urged elementary and secondary schools to reopen amid a debate between parents, teachers and local governments over how they should operate during the pandemic.
In Europe, where some countries are reopening schools after winter shutdowns, more governments are pushing in-school testing as they try to balance a growing urgency to get children back into classrooms with fears about the new highly infectious virus variants.
Austria, which this month reopened schools after nearly three months, is taking this further than any other European country.
