DETROIT (AP) — A growing number of U.S. school districts are moving back to online classes because of the winter surge in COVID-19 cases.
In Detroit, the shift involves 50,000 students.
The change once again leaves parents juggling home and work schedules around the educational needs of their children.
The vast majority of districts appear to be returning to in-person learning after winter break.
But other large school systems have gone back to remote learning, including those in Newark, New Jersey, Milwaukee, and Cleveland.
Virus infections are soaring and sidelining staff members.
The disruptions have also raised alarms about the risks to students' academic success.
In Chicago, schools were closed for a third straight day on Friday after an agreement failed to be reached between school leaders and the teachers union over virus safety protocols.
Because of the surge in COVID cases, the teachers union wants to go back to remote learning, the Associated Press reported.
