The University of Notre Dame suspended in-person classes on Tuesday, eight days after the school’s fall semester began and after 146 students and a staff member tested positive for the coronavirus, officials said. The two-week suspension, which is effective Wednesday for the school’s 12,000 students, came one day after the University of North Carolina-Chapel Hill made a similar announcement and as Michigan State University on Tuesday ordered undergrads to stay home for the rest of the fall "effective immediately."
