California Gov. Gavin Newsom on Thursday evening announced he's enacting a "statewide order" for its nearly 40 million residents to "stay at home," a wide-reaching measure for the most populous state in the country as the coronavirus spreads.

The order taking effect midnight on Friday morning. The order prohibits gatherings outside and required nonessential businesses to close. The measure is intended to slow the spread of the virus.

“We need to bend the curve in the state of California,” Newsom said during a news conference. “There’s a social contract here. People, I think, recognize the need to do more. They will adjust and adapt as they have.”
