Due to a positive COVID-19 case reported Sept. 26, the entire eighth grade class at Camden Rockport Middle School is under a 14-day quarantine.

Superintendent Maria Libby confirmed Sept. 28 that the quarantine is taking place until Oct. 8. Twelve teachers are also under quarantine, she said.

The quarantine is required for anyone who came into close contact with the person who tested positive. Libby said her understanding is that the Center for Disease Control defines close contact as as anyone who came within 6 feet of the infected person for a cumulative period of 15 minutes in a day with or without a mask.

"It was determined that was the entire eighth grade class as well as 12 teachers," Libby said.

Students are in cohorts for classes, she said, but this did not make a difference due to lunch and recess arrangements.

The time that teachers are in quarantine varies depending on last contact with the infected person, she said. "Teachers are essential workers and may be able to return upon a negative test to teach, but will need to quarantine otherwise," according to Libby.

The Camden area school district sent out a letter to parents Sept. 26.

"Dear Families, This letter is to inform you that an individual associated with the Camden Rockport Middle School recently tested positive for Coronavirus Disease 2019 (COVID-19).

Because of our safety protocols, we have in place (masking, distancing, sanitizing, etc…) we are hopeful that there may not be secondary cases. Please monitor yourself and your children for signs and symptoms. Call a health care provider if you have any symptoms," the letter stated.

From Sept. 26 to 28, the number of active COVID-19 cases in Knox County, as reported by Maine Center for Disease Control, went from five to 9. Only one of those cases is known to be related to the middle school. However, on Sept. 29, Maine CDC removed two cases from Knox County's numbers, without providing explanation.
