This is the CBS Evening News with Nora O'Donnell, reporting from the nation's capital.

Good evening and thank you for joining us.

We're going to begin tonight with breaking news, what New York's governor is calling a matter of life and death.

He's the first governor to order a containment zone here in the U.S.

and to call on the National

Guard to help prevent the spread of the coronavirus. Today, the death toll here reached 30. Confirm

cases now top 900. Across America, life is changing rapidly. Hundreds of schools and colleges

are closing nationwide. And the list of businesses telling employees to work from home is growing.

And large gatherings, including some sporting events and concerts, are now being called off.

And the big question, which we put to the president, why haven't more people been tested?

Our team is covering every angle.

Meg Oliver leads us off from New Rochelle, New York.

And Meg, you're just outside that containment zone, which is now home to one of the largest

virus clusters in the U.S., right?

Nora, that's right here in New Rochelle. They're setting up a one-mile containment area around

that synagogue, considered to be the epicenter of the coronavirus cases here.

This is not a quarantine, but a ban on large gatherings inside the zone.

This is literally a matter of life and death.

New York's governor announced unprecedented action, calling in the National Guard to try to prevent the spread of coronavirus with a containment area in New Rochelle, population near 80,000, considered the epicenter in this state.

Tonight, they're among more than a dozen states under a state of emergency.

More than 100 schools or districts in the U.S. are now closed.

It's devastating not knowing what you're going to do last minute in regards to babysitting and daycares.
