SUDBURY -- Four classes at Ecole Secondaire Catholique de Hearst are in isolation after a positive COVID-19 case.

The school's website says one person tested positive, however whether it was a student or staff member has not been released.

While the school remains open, four classes are in isolation as a precaution.

"It is important to note that a confirmed case at a school does not mean the individual was exposed to COVID-19 at the school," the French Catholic school board said in its COVID-19 Advisory Notice. "If public health orders that a class, cohort or school should be closed for a period of time, parents/guardians, students and staff will be notified immediately."

A total of 1,910 positive cases have been recorded at Ontario schools since classes resumed in September, the province said on its website. Of those, 1,063 have involved students, with the remainder among staff or unidentified individuals.

"In some instances, the type of case has not been identified as either student/child or staff/provider/partner due to privacy considerations," the province said on its COVID website page. "These individuals only include unidentified students/children or staff/providers/partners and not visitors or parents. These cases will be tracked as individuals but not included in the student/child or staff/provider columns."

A total of 593 schools have reported cases, out of 4,828 schools in the province, or 12.28 per cent. No schools are currently closed because of an outbreak.
