Through the month of March, though, cases have ticked back up.
More on the COVID-19 pandemic
Massachusetts' statewide school mask mandate was lifted at the end of last month, leaving each district to decide on its own whether facial coverings would be required.
The total number of positive COVID-19 cases reported by the DESE takes into account school districts (including charter schools), collaboratives, and approved special education schools. The data only represents what has been reported to the state.
The state had stopped publicly reporting the school data in mid-June as school was winding down and cases were dropping. The report on June 16, 2021, included only 53 new cases in students and 5 among school staff.
