LANSING, Mich. (AP) — Faced with the country’s highest rate of new coronavirus infections, Michigan Gov. Gretchen Whitmer on Friday urged a two-week suspension of in-person high school classes, all youth sports and indoor restaurant dining.

She stopped short of ordering restrictions, instead asking for voluntary compliance to slow the spread of COVID-19.

High schools should shift to virtual learning, both school and non-school youth sports should be paused, people should choose outdoor dining or takeout instead of indoor seating, and they should avoid gathering with friends indoors, she said.

The governor has resisted reinstating past restrictions such as a stay-at-home order or bans on indoor dining, in-person instruction and youth contact sports that were criticized by Republican lawmakers and others. A mask requirement remains, as do capacity limits and caps on gathering sizes.

“It is less of a policy problem that we have and more of a compliance and variant issue that we are confronting as a state,” she said.

But she did not rule out future restrictions, saying nothing is off the table.

“At this point, we think it’s important that people understand how very serious this moment is,” she said.

Whitmer’s recommendation to temporarily close high schools received mixed reactions in education circles.

The Michigan Education Association, the state’s biggest teachers union, encouraged similar action for lower grades, community colleges and universities. But the Great Lakes Education Project, a conservative group with ties to the DeVos family, said kids deserve “safely open classrooms.” Superintendents also appeared frustrated.

“Educators have been focused on doing what is best for our students’ learning and social growth. We’ve relied on health experts to guide us on the safest way to do that and any shift from that or expectation that educators alone can make those decisions in not the right approach,” said Robert McCann, executive director of the K-12 Alliance of Michigan, a coalition of superintendents.

The Democratic governor also renewed her call for the federal government to send additional vaccines. The state health department issued guidance strongly encouraging high schools that remain open for face-to-face instruction to enroll in the state’s rapid coronavirus testing program, which was recently mandated for teen athletes.

As of Thursday, Michigan had the worst rate of new COVID-19 cases in the U.S. over the previous two weeks. Related hospitalizations had more than quadrupled in a month and were 88% of the statewide peak from a year ago, leading some hospitals to postpone non-emergency surgeries. The seven-day average of new daily deaths has been rising for two weeks. About 39% of the state’s residents ages 16 and older have gotten at least one vaccine dose.
