Here's how the news unfolded Sunday. All times Eastern.
12:21 a.m. Washington to shut down bars, eliminate in-person dining
Washington state is following the national trend shuttering entertainment venues and recreational facilities, and limiting restaurants to delivery and take-out.
Governor Jay Inslee released a statement Sunday night local time announcing that he will sign the statewide proclamation on Monday.
The ban will not apply to grocery stores and pharmacies, although other retail outlets will have reduced occupancy, the statement said.
“These are very difficult decisions, but hours count here and very strong measures are necessary to slow the spread of the disease," Inslee said.
Washington's King Country, which includes the county seat of Seattle, has been one of the centers of the coronavirus outbreak in the U.S.
12:11 a.m. Los Angeles closing bars, clubs and gyms
Los Angeles Mayor Eric Garcetti announced that the city will be closing bars, nightclubs, entertainment venues and gyms until at least March 31.

The order extends to libraries, recreation centers and zoos.
Grocery stores, pharmacies and food banks will remain open, the mayor said. In addition, the announcement included a moratorium on evictions for renters.
The executive order, which came an hour after New York City made a similar announcement, puts the United States' two largest cities under unprecedented restrictions during a national health crisis.
The Los Angeles closures go into effect Sunday at midnight local time.
"This will be a tough time, but it is not forever. Angelenos have always risen to meet difficult moments, and we will get through this together," Garcetti said in a statement.
11:17 p.m. Peace Corps to suspend worldwide operations
The Peace Corps is suspending all activities around the world in 60 countries, effectively shutting down the service for the time being.

10:05 p.m. NYC to shutter bars, limit restaurants to takeout and delivery
New York City becomes the latest city in the U.S. to order the mandatory closure of all bars, movie theaters and entertainment venues, per an announcement by Mayor Bill de Blasio.
In addition, restaurants and cafes will be limited to food take-out and delivery only.
The closures will go into effect Tuesday at 9 a.m.
“This is not a decision I make lightly,” De Blasio said in a statement. “These places are part of the heart and soul of our city. They are part of what it means to be a New Yorker. But our city is facing an unprecedented threat, and we must respond with a wartime mentality.”
The announcement came just hours after the mayor announced the cancelation of classes in the city’s public school system.
Several other U.S. cities have announced similar restrictions.
8:40 p.m. Red Cross in urgent need of blood
The number of blood drive cancellations is “growing at an alarming rate,” according to the Red Cross. About 1,500 blood drives have been canceled so far, resulting in 46,000 fewer blood donations, according to the organization.
In light of coronavirus concerns, the organization is taking additional precautions at blood-donation facilities, including monitoring the temperature of staff and donors, providing hand sanitizer, increasing enhanced disinfecting of surfaces and equipment, and spacing beds where possible.
Red Cross officials are reminding people that donating blood is a safe process, and that they should not hesitate to donate if they are healthy and eligible to give blood.
8 p.m. CDC recommends eliminating large gatherings
The Centers for Disease Control and Prevention has issued new recommendations that mass gatherings of 50 or more people be canceled or postponed for the next eight weeks.

5:52 p.m. New York City closes public schools
New York City Mayor Bill de Blasio announced Sunday that the city's public school system is canceling classes as of Monday morning to combat the spread of the coronavirus.
The mayor said that all New York City public schools will be closed through at least Monday, April 20, at a minimum, and at a maximum the entire remaining school year could be canceled.
The unprecedented decision will shutter schools for the nation's largest school system, leaving more than a million students at home.
De Blasio said the Department of Education is working to roll out an ambitious remote learning program that is slated to begin next week.
School officials said they had determined that approximately 300,000 of the system's 1.1 million students do not have a connected device, and administrators were working with Apple to purchase 300,000 iPads to loan to those students so they could participate in the school system's distance learning program.
"I am distraught at having to take this action, but I became convinced over the last few days that we have no other choice," de Blasio said about the decision to close the city's schools. "We've seen the latest models [regarding the spread of the virus] ... it's a sacrifice that has to be done."
The mayor said that as of Sunday, New York City has 329 confirmed coronavirus cases, up from a few dozen last week. Five city residents have died from the coronavirus.
Connecticut Gov. Ned Lamont also announced Sunday that schools in that state would close from Tuesday through at least March 31.
Students who receive meals through the school lunch and breakfast program will be able to continue receiving meals while classes are canceled, similar to the way summer meals are operate, Lamont said.
Officials in Arizona and Montana announced that schools in those states will be closed until March 27 as well.

11:36 a.m.: New York governor wants federal troops to be mobilized to fight coronavirus
In an op-ed in The New York Times, New York Gov. Andrew Cuomo is urging President Donald Trump to let states take over coronavirus testing.
Cuomo also asked the president to mobilize the Army Corps of Engineers to expand hospital capacity.
"States cannot build more hospitals, acquire ventilators or modify facilities quickly enough. At this point, our best hope is to utilize the Army Corps of Engineers to leverage its expertise, equipment and people power to retrofit and equip existing facilities — like military bases or college dormitories — to serve as temporary medical centers," Cuomo said.
"We believe the use of active duty Army Corps personnel would not violate federal law because this is a national disaster," Cuomo wrote. "Doing so still won’t provide enough intensive care beds, but it is our best hope."
There are 729 cases of COVID-19 in New York, the most of any state in the country. Of those 729 people, 137 are in hospitals.
At a news conference Sunday, Cuomo urged private businesses to “aggressively consider” working from home and voluntary close. He did not rule out taking more action.
