Gov. Whitmer makes announcement Monday.

Following the lead of seven other states, Gov. Gretchen Whitmer on Monday announced a stay-home order for the state of Michigan, requiring people to stay indoors except for essentials. The order will be in effect at least three weeks.

It restricts movement that is "not necessary to sustain or protect life" and allows people working in some professions to continue to go to work. Some outdoor activity and grocery and hospital visits are also allowed.

Workers in more than a dozen sectors are exempt, including health care, public safety, public works, energy and “critical” manufacturing.

Government functions like public transit, trash pick up, and park maintenance can also continue.

The order still lets people leave home to shop for food or medicine, seek medical treatment, get gas, walk pets and exercise.

It does prohibit gatherings of any size outside of a home. Though places of worship remain exempt from penalties for violating the order.

Michigan joins Ohio, Louisiana, New York, California, Illinois, Connecticut and New Jersey in issuing the "shelter in place" order.

Whitmer said that the number of confirmed cases doubled over the weekend, and since there is no cure or vacine, isolating people was one of the most effective ways to stop the virus from spreading.

If we don't stop, she said, the hospitals will be quickly overwhelmed with cases.

She said there's a projection by experts, that if things spun out of control in Michigan, 70 percent of the 10 million people would be infected. And of that, one million would need to be hospitalized.

"We have about 25,000 acute-care beds in Michigan," she said. "Think about that. That’s where we are headed currently, so stopping the spread of this virus is the most important tool we have right now to keep our community safe."

On Sunday morning, Whitmer did the rounds on the cable TV news shows, including Fox News, and defended her decision not to do a statewide lockdown, but hinted that could change.

"Trust me, we are continuing to determine what we need to do to keep people safe, and to keep our health systems from being overwhelmed," Whitmer told Fox News host John Roberts.

On ABC's "This Week," she said: "We're all building the airplane as we fly it right now. We're doing the best that we can."
