From the definitions page:
“Staff” refers to all adults working or volunteering in a school (e.g. teachers, principal, social worker, educational assistants, custodian, lunch-room monitor). “Non-staff” refers to the students in the school. At this time, school cases are not tracked by status (i.e. active, recovered) as it is assumed that all active cases are no longer attending school in person and therefore do not pose an infection risk to the school community. This data relates only to schools that have a current active outbreak.
