Seven Northland schools were removed from the Minnesota Department of Health's outbreak list Thursday.

A school building is put on the list if it reports five or more confirmed cases of COVID-19 in students or staff who were in a building while infectious during a two-week reporting period. The building is removed after 28 days of no new positive tests.

Schools removed include Cloquet Middle School, Cloquet High School, Hermantown Middle-High School, Esko High School, Vandyke Elementary School in Coleraine and Lincoln Elementary School in Hibbing.

As of Thursday, four new school buildings were added to the list and 93 were removed for a total of 212.

From Dec. 13-19, there were 495 more positive COVID-19 cases in schools statewide, with 268 new cases among staff and 227 new cases among students. Statewide, 18 more school buildings reported at least one new case of COVID-19.
