COLUMBUS, Ohio (WCMH) – 23,052 students and staff members in Ohio schools have tested positive for the coronavirus this school year, according to the latest weekly numbers published Thursday by the Ohio Department of Health.

Thursday’s week-to-week increase in cases was 3,750, the lowest since Nov. 12. This week is the second straight week that the increase in school cases was lower than the previous week. That could be, however, because of decreased COVID-19 testing statewide in the days after Thanksgiving.

  • Sept. 17: 319
  • Sept. 24: 739 (+420)
  • Oct. 1: 1,274 (+535)

Case criteria

  • Full-time or part-time students and staff who have tested positive for or been diagnosed with COVID-19. Infections were caught in and out of school.
  • Staff members include teachers, administrators, coaches and support staff.
  • Excludes students/staff who are completely remote, but includes them if they were “on-site” while infectious.

  • ODH reports “new” and “cumulative” cases. Cases only move over to “cumulative” once the person is no longer COVID-positive. NBC4’s count of new cases every week reflects the change in “cumulative” cases. More info
