Faced with a steep rise in Covid-19 cases, the local county health department has issued an emergency “stay in place” order for all undergraduates at the University of Michigan at Ann Arbor, effective immediately.

The decision by the Washtenaw County Health Department — which was supported by university officials — comes after a series of dorm outbreaks that fueled a dramatic increase in cases of the virus on campus.

The surge in infections on the campus contributed to a “critical” situation overall in Ann Arbor, according to local health officials, who noted that university students now represent more than 60 percent of local cases.

Some of that Covid spread is a result of Michigan students partying irresponsibly. But university leaders have also been roundly criticized for failing to take enough precautions when reopening.

The 14-day health-department order allows students to attend class, but they cannot socialize. The order will not affect the University of Michigan Wolverines’ football schedule.

University officials on Tuesday pledged to provide additional safety options for students and instructors, including moving more undergraduate courses to online instruction for the remainder of the semester.

This latest effort to control Covid at Michigan may or may not work. But in the meantime, frustrations on campus are growing.
