After a difficult year or more of virtual learning, parents are eager to have their children back in classrooms. But even as the highly transmissible delta variant surges, school districts like Daniels’ aren’t beefing up protocols to prevent infections. Masks aren’t mandated or enforced, according to teachers, parents and officials in several states. Physical distancing is nearly impossible. To top it off, students exposed to covid may not be required to quarantine despite guidelines from the Centers for Disease Control and Prevention, risking an even more rapid spread among children, the youngest of whom aren’t yet eligible for vaccination.
