Michigan State University, meanwhile, opted to go online on Tuesday, just two weeks before classes were expected to start.

Insider has compiled a list of schools who have suspended classes or quarantined students because of COVID-19. You'll find information on all of them below.

University of North Carolina at Chapel Hill is going remote for the fall semester

UNC announced on Monday that it was suspending in-person classes after the school's COVID-19 positivity rate jumped from 2.8% to 13.6% in just one week.

According to the school's COVID-19 dashboard, 130 people on campus tested positive for the virus between August 10 and August 16 — up from 10 the week prior.

In the school's announcement about remote learning, officials said 177 people were in isolation because of the virus, and another 349 were in quarantine.

"There are no easy answers as the nation navigates through the pandemic. At this point, we haven't received any information that would lead to similar modifications at any of our other universities," university president Peter Hans said in the statement. "Whether at Chapel Hill or another institution, students must continue to wear facial coverings and maintain social distancing, as their personal responsibility, particularly in off-campus settings, is critical to the success of this semester and to protect public health."

University of Notre Dame is suspending classes for two weeks

University of Notre Dame suspended in-person classes for two weeks on Tuesday, just eight days into the semester, after 146 students tested positive for COVID-19.

These are difficult times, so please be attentive to both your physical and emotional well-being," the school's Vice President for student affairs, Erin Hoffmann Harding, said in a statement. "Notre Dame's desire to offer an on-campus experience stands at great risk, yet we are here to support one another. Preventing further spread requires urgent action from each of us."

Michigan State University shifted to remote learning just two weeks before classes were supposed to start

Michigan State President Samuel Stanley announced all in-person classes were canceled for the fall semester on Tuesday.

The school hadn't yet opened its dorms to students, but Stanley said the school decided to go remote after seeing outbreaks on other campuses.
