Another person at Troy Howard Middle School has tested positive for the coronavirus, according to Regional School Unit 71 Superintendent Mary Alice McLean.

The whole sixth grade has been placed in remote learning because most of the sixth grade teachers were exposed to the individual, McLean said. She added that 22 sixth graders and seven teachers will have to quarantine until Dec. 1.

Seventh and eighth grade classes were not affected, McLean said. This is the fourth case in the district and thesecond at Troy Howard. There have been no confirmed cases associated with any of the individuals who tested positive to date.

The school could move to staggered student attendance if cases are detected after Thanksgiving break, she said. The Department of Education continues to classify Waldo County schools as "green," or safe for in-person attendance.

In a Nov. 20 email, McLean asked families to stay home and only celebrate Thanksgiving with immediate family members to reduce the risk of COVID-19 exposure.

She reminded families that people traveling to a state not exempt from quarantine under Gov. Mills' executive order must stay home for 14 days or quarantine until they receive a negative coronavirus test.

"Please continue to help us enable our wonderful students and staff to learn together in school though doing your part," she said in the email. "It has never been so clear how deeply interconnected and how we are impacted by one another in invisible ways, simply by breathing."
