Gallagher said it was reported there was little evidence of mask wearing or physical distancing.

In some cases, students who were supposed to be quarantined due to a family exposure still participated in out-of-school activities.

There have been two positive cases of Covid-19 connected with these parties according to Gallagher.

The quarantines have impacted students at Northville High School, along with siblings at the district’s middle and elementary schools.
