NEW YORK — Another 12,723 cases of coronavirus among students and staff in public schools were called in to the city’s Situation Room Tuesday, but the city says 85% of tests were administered during the winter break.

In all, the Department of Education is reporting that there have been 61,453​ cases since September, up from 21,828 cases that had been logged as of Dec. 22.

That’s many more cases in just a few weeks than had previously been recorded in three months of school. The DOE cautioned that they’re now counting rapid tests and self-reported positives.

Previously, the city only counted a case if it had been confirmed with state laboratories.

The surge also comes as the city urged all students to get tested before classes resumed Monday.

Still, the staggering increase is an indication of how contagious the virus has been across the city.
