Thirty-five cases of COVID-19 over a period of two weeks were reported in Regional School Unit 5 on Friday, according to an email from Superintendent Becky Foley.

In addition to 13 cases at Freeport High School, two were reported at Mast Landing School, eight at Durham Community School, four at Pownal Elementary School and two at Freeport Middle School since the superintendent’s last update, which was on Nov. 23.

Regional School Unit 5, which serves Freeport, Pownal and Durham, has recorded 114 total positive cases of COVID-19 since the beginning of the 2021-22 school year so far, Foley said Friday, more than half of which have been identified over the last month.

For comparison, during the 2020-21 school year around 67 cases were identified in RSU 5. There are 1,990 students enrolled in RSU 5 across six schools. Attempts to contact Foley for further comment on Monday were unsuccessful.

According to Maine CDC Spokesperson Robert Long, the Delta variant of COVID-19 is largely to blame for the uptick in cases this year.

“The dominant strain in Maine since late summer, it is far more transmissible than COVID-19 strains that were infecting Maine people at this time last year,” wrote Long in an email. “The increase in cases among students aligns with increases in cases among other age groups, with most of the cases being among individuals who were not fully vaccinated.”
