DETROIT (AP) — Students at the University of Michigan must stay in place for two weeks after a surge of coronavirus cases driven by social gatherings on and off campus. The Washtenaw County health department says the surge is overwhelming its ability to confront the pandemic. More than 1,000 students have been infected since the start of the fall term, despite limits on the size of gatherings and classes that are mostly held online. Students can attend in-person classes and also leave their residence for exercise, work, food, medical appointments, voting and religious services. The restrictions end on Nov. 3.
