The Democratic leaders are pressing Trump's outbreak response. And Congressmen Paul Gosar and Ted Cruz both met a person confirmed to have COVID-19.

WASHINGTON — Italy took a page from China’s playbook Sunday, locking down some 16 million people in northern parts of the country, including Milan and Venice, for nearly a month to help stop the new coronavirus across Europe.

In the U.S., the Grand Princess cruise, where 21 people have tested positive, was headed to Oakland. The ship will remain in international waters for at least another day as officials work on plans to transport passengers to facilities around the country, as they'll face quarantines ashore.

The largest school district in Northern California has canceled classes for a week after it was discovered that a family in the district had been exposed to COVID-19. The Elk Grove School District, which is near Sacramento, has nearly 64,000 students.

China has suffered about three-fourths of the world’s 109,000 coronavirus infections and most of its 3,800 deaths, according to The Associated Press.

The U.S. death toll from the virus hit 21 on Sunday. As testing increased, the number of infections in the United States climbed above 500.

Pelosi, Schumer: Trump needs to support help for outbreak

9:45 PM EDT

The two top Democratic leaders in Congress are calling on President Donald Trump to support a series of steps to help Americans deal with the coronavirus outbreak — from paid sick leave to widespread and free testing and other moves.

House Speaker Nancy Pelosi and Senate Democratic leader Chuck Schumer said Sunday that Trump should put the health and safety of the public first.

They said such steps should take priority over moves to help companies deal with financial losses — like tax cuts for corporations.

Among the steps they are pushing: paid sick leave for workers impacted by the quarantine orders and enhanced unemployment insurance for workers.

Oil plunges 20% as another virus-fueled trading week begins

7:45 PM EDT

Oil prices are plunging amid worries that an OPEC dispute will lead a virus-weakened economy to be awash in an oversupply of crude.

Brent crude, the international standard, lost $9.55, or 21.1%, to $35.72 per barrel, as of 7 p.m. Eastern time on Sunday. Benchmark U.S. crude fell $8.60 to $32.68.

The dramatic losses follow a 10.1% drop for U.S. oil on Friday, which was its biggest loss in more than five years.

Prices are falling amid worries that producers won't cut supplies enough to match falling demand.

The new coronavirus has hit travel and threatens to slow economies around the world.

At least 10 people were killed and another 23 are missing after a hotel being used in China's coronavirus fight suddenly collapsed.

Authorities said Sunday that 71 people had been trapped following the collapse of the five-story building in the city of Quanzhou the previous evening.

Firefighters working through the night and into the next day rescued 38 people. The hotel was housing people who had come from areas hit hard by the epidemic. All of them had tested negative.

Chinese cities are isolating people from hard-hit areas for 14 days. The cause of the collapse is under investigation.

Cruise ship hit by virus to dock in Oakland, California

1:12 a.m. EST

The captain told passengers Saturday night that a cruise ship hit by the coronavirus is headed to the port of Oakland, California.

Grand Princess Capt. John Smith told passengers in an audio address that the ship will dock in Oakland, California, likely on Monday. Smith told passengers that people who require “acute medical treatment and hospitalization” will be taken to health care facilities in California.

Other guests will be taken to federally operated isolation sites or transported out of California. The captain said he was not given any information about non-U.S. citizens.

Carnival Cruise Lines officials said earlier Saturday that there are citizens of 54 countries aboard the ship.

The Grand Princess had been forbidden to dock in San Francisco amid evidence that the vessel was the breeding ground for a cluster of nearly 20 cases that resulted in at least one death after its previous voyage.

Officials confirm first coronavirus case in nation's capital

12:05 a.m. EST

Officials in Washington, D.C., say a man in his 50s has tested positive for coronavirus, marking the first presumptively confirmed case in the nation’s capital.

District of Columbia Mayor Muriel Bowser said Saturday that the man started exhibiting symptoms of COVID-19 in late February and was hospitalized Thursday. She said another man, from Nigeria, who had passed through Washington has also tested positive for the virus in Maryland.

President Donald Trump says he isn't concerned “at all” about the coronavirus getting closer to the White House after the first Washington case and an attendee of a recent political conference where Trump himself had spoken also tested positive for the virus.

Nineteen people have died in the U.S. from the virus. The number of infections in the U.S. has swelled above 400.

To put the coronavirus numbers in context, millions of Americans get the flu every single year and there are thousands of flu deaths annually. Since October 2019, the CDC estimates around 32 million Americans have gotten the flu. That’s one in every 10 Americans.
