Jay Inslee, the governor of Washington, announced new restrictions on residents and businesses as the state deals with record-breaking COVID-19 infection rates.
The state is currently undergoing a "third wave" of transmission as average daily cases have doubled in the last two weeks, Inslee told reporters at a news conference. Daily case numbers have surpassed the highs in March, he noted.
"Inaction is not an option," Inslee said. "We have to take bold decisive action."
Starting Monday at 11:59 p.m. local time, indoor social gatherings with people from outside the household are prohibited unless the guests have quarantined for 14 days or they have quarantined for seven days and received a negative test result 48 hours before the event.
Outdoor gatherings should have fewer than five people from outside the household, Washington state officials said.
Indoor dining at restaurants and bars will stop but outdoor dining and takeout remains unchanged. Gyms, movie theaters, bowling alleys and museums are closed, and weddings and funeral receptions are prohibited. Ceremonies are limited to 30 people.
Indoor retail is limited to 25% capacity and religious services are limited to 25% capacity or 200 people, whichever number is less. Choir performances are prohibited.
The measures will be in effect until Dec. 14.
"We know these measures can work," Inslee said. "We've shown the country they can work."
Washington state was the first in the U.S. to experience an outbreak of COVID-19 cases at the beginning of the year.
The new restrictions are in addition to a number of protocols for universities Inslee instituted last month after multiple campuses saw a jump in COVID-19 cases.
