There's still a lot that experts don't understand about this virus, but we're seeing that it can spread quickly and confined spaces like that cruise ship.

We're also seeing that that told Jump every single day this morning.

More than 700 people have died from the Corona virus, including the first American.

This morning.

The first American has died from the Corona virus since the outbreak began.

The U.

S Embassy confirms a 60 year old victim was being treated at a hospital in Wuhan, China.

Also this morning, for the first time we're hearing from an American infected with the virus, Rebecca Frasier tells ABC News that she's among at least a dozen others who have contracted Corona virus On board this cruise ship off the coast of Japan.

The ship remains quarantined.

The only thing that I was told yesterday when I found out I was diagnosed Waas that the hospital stay would end up being 14 days instead of the initial three.

That's very concerning to me.

So far, her husband has tested negative.

I'm concerned because my husband is so on the ship.

And what is he supposed to do if he's released?

And I'm not overnight?

Another flight evacuating from the hot so carrying Americans from Wuhan arriving in the U.

S.

This time at a military base in Nebraska, all 57 passengers will now be quarantined for it least two weeks thistles.

Some evacuees have been split from their families.

Greg Wyshynski and his three year old daughter are quarantined in California.

Frank's wife was forced to stay behind in China because she's not a U.

S citizen.

He just found out she's become infected with Corona virus. 00:01:55.010 --> 00:02:1.780 She had your dad chest X rays, which show no fluid. 00:02:2.890 --> 00:02:22.140 Don't you know she's having problems breathing, even keeping calm down With that latest white coming back to the United States, there are now more than 1000 Americans who are quarantined on military bases all across the country with incredible what they're going through.

Will car for us.

Thank you.

We do want to bring in ABC News Chief Medical correspondent Dr Jennifer Ashen joining us from Massachusetts this morning.

Dr.

Ashton, you've been following all of this very closely.

First, I know you've also been speaking with officials at the National Institutes of Health, and I understand you're learning more about the numbers being reported here.

Exactly.

And it's really important when we hear these numbers.

We have to pay attention to the numbers in China and then distinguish that from the numbers here in the U.

S.

The concern about the numbers in China is that not all people who may be infected or even sick with this novel Corona virus may be able to be tested. 00:02:59.590 --> 00:03:1.220 So we hear that number go up. 00:03:1.220 --> 00:03:3.350 30,000, 32,000. 00:03:3.440 --> 00:03:13.900 Remember there there are 11 million people in Wuhan, and obviously the Chinese do not have the ability right now to test everyone in that area.

So we have to interpret those numbers with caution because they may or may not be accurate.

And aside from the uncertainty about the numbers, what are the other challenging aspects of this global health emergency and specifically the ability of countries to work together on this.

The biggest thing right now it is that the CDC has not been allowed inside China and on the ground to evaluate the data and assess the clinical response.

We're hoping that will happen any day now.

But again, in terms of the response, especially here, the ability to identify and then isolate with quarantine and travel restrictions while it may not be convenient is key to containing this outbreak.

Absolutely Dr Action for us.

Thank you so much.

We appreciate it.
