Montana is the latest state to order all of its citizens to stay home except for essential work and limited outdoor activities.
The order goes into effect on March 28.
"With 90 cases in our state today... we have to do more to curtail the spread of this virus," Gov. Steve Bullock said at a news conference Thursday to announce his emergency order.
“I'd rather be accused of overreacting than to have our health care system overwhelmed,” Bullock added at the briefing in Helena. “In order to have a healthy economy, we need to have a health population.”
