All students on the University of Michigan's Ann Arbor campus are being told to stay home, except for a handful of in-person classes, for the next two weeks. The school asked students to limit their time outside their residence following a recommendation from the county health department. It comes days after the university's athletic department suspended all operations for 14 days to try to slow the spread of a variant strain of the coronavirus. “We are very concerned about the potential for this variant to spread quickly,” Jimena Loveluck, health officer for Washtenaw County, said in a news release. “We are working closely with the university to take coordinated steps to control the current outbreak and understand the situation more fully. This stay-in-place recommendation will help us reduce the impact of the variant and COVID-19 in general as we investigate.”
