(AP) Many schools in Maine are just a week into the year, and a few are already moving to remote learning because of COVID-19 cases.

Mildred L. Day School in Arundel demonstrates the difficulties schools are facing. Officials said 143 people were identified as close contacts following COVID-19 cases, forcing the move to remote learning.

“I guess kind of expected in a way, sadly. Delta is really contagious. Kids are like – I’m sure they’re trying to keep their masks on but…” parent Tara McNeal told WMTW-TV.

Last month, a school in northern Maine was forced to return to remote learning after a staff member tested positive for the virus.
