Temple University will "pause" in-person classes for two weeks after identifying 103 active coronavirus cases on campus, the university said Sunday.

Of the COVID-19 cases, 58 were reported on Friday.

The Philadelphia university believes the cases were spread during "small social gatherings happening off-campus," according to a letter to the campus community emailed on Sunday.

“We are hopeful, of course, that we will be able to return to the full hybrid program in place at the start of the semester, but any such decision will be driven by the data and public health guidance available at the time," University president Richard Englert said.

In-person classes will be held virtually starting Monday and lasting through Sept. 11. A small number of classes that must be held in person may continue, the letter read, though only if deemed essential by administrators.

Classes already scheduled to be online will continue as planned.

Most Temple students returned to class less than one week ago, on Aug. 24. Colleges and universities all over the country have been wrestling with how to return to class. Many are holding all or most classes online.

Other schools have also blamed off-campus gatherings for new cases of COVID-19.

Over the weekend, city health officials urged all college and university students to avoid social gatherings with people outside of their household and to wear masks when they cannot avoid such contact.
