While the U.S. struggles to play "catch up" in the fight against coronavirus, states with the most cases and deaths are making their own rules to try to stop the disease.
From emergency declarations to banning large crowds, here's what some of the hardest-hit states are doing:
This is where the first U.S. case and the first U.S. death from coronavirus were reported. Now, Washington state now has at least 30 deaths.
At least 11 nursing homes have been hit with the disease, including one linked to 19 deaths.
Gov. Jay Inslee has banned large events with more than 250 people in King, Snohomish and Pierce counties, which includes Seattle.
He also directed homes and assisted living facilities to limit the number of visitors, keep visitors in patient rooms and screen workers every shift for coronavirus symptoms. The rules are in place until midnight April 9.
"This is an unprecedented public health situation," Inslee said. "One main defense is to reduce the interaction of people in our lives."
New York state has a cluster of coronavirus so big, Gov. Andrew Cuomo ordered a 1-mile containment zone.
But it's not in New York City. It's in the suburb of New Rochelle, a city of about 80,000 people and at least 108 cases of coronavirus.
Starting Thursday, schools, houses of worship and other places used for large gatherings will be closed for two weeks, Cuomo said.
The National Guard will be deployed to clean public areas within the containment area and deliver food to homes.
And a satellite testing facility will be set up in partnership with Northwell Health.
The outbreak in New Rochelle started with one resident, an attorney who works in Manhattan, and spread to 100 people in less than 10 days.
All public gatherings should be postponed or canceled until at least the end of March, Gov. Gavin Newsom said in a statement.
California has had four deaths so far.
The governor's office said those unable to work because they're taking care of a family member who's quarantined or sick with coronavirus can file a paid family leave claim if they have medical documentation.
Newsom declared a state of emergency for California, which will "protect consumers against price gouging, allow for health care workers to come from out of state to assist at health care facilities, and give health care facilities the flexibility to plan and adapt to accommodate incoming patients," the governor's office said.
Massachusetts Gov. Charlie Baker also declared a state of emergency.
The governor also issued guidance for Massachusetts' executive branch, including canceling out-of-state travel for work, canceling gatherings in favor of virtual conferences, and encouraging employees to not come in to work with fever or flu symptoms.
That guidance will be reevaluated in a month or sooner if circumstances change.
And the state's education department "is providing local schools with relief from attendance and school year requirements so that schools have the flexibility to make decisions on temporary closures," the governor's office said.
