As omicron continues to surge, families despair over return to remote learning

The vast majority of U.S. districts appear to be returning to in-person learning, but other large school systems including those in Newark, New Jersey, Milwaukee and Cleveland have gone back to remote learning as infections soar and sideline staff members. Dozens of smaller districts have followed, including many around Detroit, Chicago and Washington. The disruptions also raise alarms about risks to students. Long stretches of remote learning over the last two years have taken a toll, leaving many kids with academic and mental health setbacks that experts are still trying to understand.
