SEVERAL positive cases of Covid have been reported in schools across County Durham in the first week of classrooms reopening after a two-month lockdown. Students have been sent home and are reverting to home learning following at least three confirmed coronavirus cases in senior schools. The Northern Echo understands infections have also been reported in some of the county’s primary schools. A spokesman for Wyvern Academy, Darlington, said: “Lateral flow tests are being carried out as part of the Government’s return to school provision and did pick up a positive result with one student. “All Department for Education procedures were followed in identifying and notifying the pupil who is now required to self-isolate.”
