SOUTHFIELD, Mich. (AP) — The continued rise in coronavirus cases across Michigan and an expected surge following Christmas and the New Year has extended the holiday break for some students.

Classes that had been scheduled to resume Monday in several districts have been cancelled or moved online.

The Detroit Public Schools Community District shut down school through at least Wednesday. Ann Arbor Public Schools in Washtenaw County will go to remote learning Wednesday through Friday.

Just north of Detroit, Oak Park Public Schools cancelled classes Monday and said learning would be held virtually through the rest of the week, while Southfield Public Schools shifted to online remote learning for the entire week.

The Lansing School District also shifted to virtual learning for the week. Teachers and staff in Lansing still will be required to report to their schools.

In Pontiac, about 30 miles (50 kilometers) northwest of Detroit, public school classes will be online until Jan. 18.The moves follow the state’s reporting of more than 25,800 new virus cases and 338 deaths on Tuesday and Wednesday.

Michigan has reported more than 1.5 million confirmed virus cases and more than 26,900 deaths since the start of the pandemic.
