Wisconsin Gov. Tony Evers said Monday that he will order the closure of all non-essential businesses Tuesday.

In a tweet, Evers also urged people to stay at home to slow the spread of the COVID-19 virus that has killed four people in the state and infected at least 400, including cases in Bayfield and Douglas counties.

Evers tweeted Monday that he would be signing the order Tuesday. It comes after the governor ordered K-12 schools and a host of other businesses closed, including bars, restaurants and hair salons. He’s also limited gatherings to no more than 10 people.

Evers' latest actions bring Wisconsin closer to Illinois, New York City and parts of California which have essentially shut down non-essential businesses and ordered people to stay home.

Evers called his coming order a “Safer at Home’’ order, stopping short of a Shelter in Place order.

"I know this has been difficult and has disrupted the lives of people across our state. That’s why issuing a #SaferAtHome order isn’t something I thought we’d have to do, and it’s not something I take lightly," Evers tweeted Monday morning. “But here’s the bottom line: Folks need to start taking this seriously.”

Evers wants people to stop all unnecessary interaction with other people and to travel only when absolutely necessary.

“You can still get out and walk the dogs — it’s good exercise and it’s good for everyone’s mental health — but please don’t take any other unnecessary trips, and limit your travel to essential needs like going to the doctor, grabbing groceries or getting medication,'' he tweeted.

In Minnesota, Gov. Tim Walz said last week he may consider a Shelter in Place order as early as this week. Walz on Monday put himself in self-imposed quarantine after being exposed to a member of his security detail who tested positive for COVID-19.
