For the eighth consecutive reporting week, Massachusetts public schools have seen an uptick in COVID-19 cases among students and staff.

The Department of Elementary and Secondary Education on Thursday reported total cases among students and staff climbed nearly 63 percent more than those reported last week, to 13,380 new cases among students and 4,043 among staff for the week that ended Wednesday.

COVID-19 related hospitalizations also increased this week among those under age 20, the highest number of hospitalizations among children in the 11 and under age group.

The rise in school cases since mid-March has prompted some districts to reassess their mask policies. Earlier this week, Northampton Public Schools announced it’s reinstating its mask mandate through May 20 due to cases increasing in the district.


School leaders in Arlington, Belmont, and Cambridge didn’t reinstate a mask mandate, but urged students to wear masks indoors after the CDC classified Middlesex County as having a high level of COVID-19 transmission.
