Officials say they didn’t receive notification about the exposure until very late on Tuesday and were unable to verify what kind of contact the person had with any infected individual. The late hour led them to, in an abundance of caution, cancel classes across the district for March 11.

Officials did stress that there has not been a confirmed case of COVID-19 in the district  — only exposure by a medical employee.
