If there was any doubt that the return to school is going to be dicey, look no further than Utah. The state announced Thursday that students and teachers will be allowed to go to school even if they have been directly exposed to the coronavirus, as long as they are not symptomatic and no one at home has tested positive, the Salt Lake Tribune reported. It’s well-established that people can have and spread the virus without symptoms. Utah is also setting guidelines for when schools must shut down after an infection—and the health department says they can stay open unless 15 people test positive in a short period of time.
