Since the outbreak at Temple, other schools have had coronavirus problems of their own. Kutztown is reporting nearly 200 cases, and Penn State's total is about 700 after reporting nearly new cases 300 on Friday.
KYW Newsradio Medical Editor Dr. Brian McDonough said most young people who get the virus are asymptomatic or show mild symptoms, and advised they should stay at school to keep their families safe.
"From a public health standpoint, if at all possible, it makes sense to stay on campus and quarantine rather than bring it to the larger community or to older relatives or people who might be sick at home," he suggested.
"And unfortunately what we're seeing so far is students are actually being pretty good when they go to class. It's those in the social settings, some of them acting irresponsibly that's bringing the virus back and that's a concern."
While Temple has transitioned to mostly all virtual classes, that hasn't happened yet at some other schools. Penn State's president says they are monitoring all of the data closely. Meanwhile, a new town ordinance in Kutztown limits social gatherings to 10 people or less and requires masks to be worn at all times in public.
