Children waiting to board a flight, the faces shielded with makeshift helmets.

People in China are taking no risks, all too aware of the consequences of catching the deadly Corona virus.

A TTE this medical facility in Wuhan, the epicenter of the outbreak.

The desperate whales of those working to save people last week speaks 1000 words.

This'll, nurse repeats.

I can't take it anymore!

This'll woman in a video circulated last week to begs to be seen.

Help Doctor help!

She screams.

I also have a fever.

Both videos has since been taken down by sensors, but fears about the outbreak have gone beyond China's borders.

Officially, 170 people have now died from the virus.

Almost 8000 cases have been confirmed by officials, and they say 12,000 Maur are suspected.

There are only 68 cases overseas, which is less than 1% of the total cases globally.

This means our measures to control the outflow of the virus are effective under pressure.

This morning, the foreign secretary assured Britain's in China, they were trying to get them out.

We've been working tirelessly for office working department Health.

Been working flat out 24 7 to try and make sure that we can identify British nationals in one hand, get them to a muster point and then get a flight to charter flights in and out on the way to the airport for evacuation.

And after a full start yesterday, the evacuation is now underway.

Since the outbreak, China is racing against time to build two new hospitals in Wuhan to meet the need caused by the virus.

At the moment, hospitals are overwhelmed, good sense of false and the whole city is under lock down.

The strain is on.

Medical workers who have been working under pressure for nearly three weeks on the number of patients is continuing to increase.

And it's not just in China where people are trapped.

6000 passengers aboard this cruise liner and Italy are unable to leave as medics monitor a couple from China with a suspected case of Corona virus.

See, you know about love.

What?

I got some more.

We spoke to my pregnant daughter on boards.

She's very agitated.

She was fine until late morning because she didn't know what was going on.

Then they heard the news.

19 countries have reported cases of the virus, but no one yet has died outside of China, something that experts say is thanks to a transformation learned from previous global incidents.

What's changed dramatically over the last five years, at least, is how well international corporation has developed on all the systems have been put in place from Internet from organizations like the W Wait Joe.

But also there's a loss of international committees that bring countries together and networks that make sure that everybody's prepared for these outbreaks.

So we're in a completely different place in the worst way.

Five years ago, before a bola.

As governments globally grapple with this tonight the focus is on the World Health Organization.

Within the next hour, they're expected to announce whether to declare this a public health emergency of international concern on your pop reporting.

Miller.

Joining us from Liverpool now is Dr Nick Beaching.

He's a specialist on clinical infectious diseases at the School of Tropical Medicine in Liverpool.

Dr.

Beating What will it mean if at around hop r seven, which is what we think might happen?

The w h o.

Do declare this a global emergency.

Well, it will increase the way we restrict the movement of people.

I think a lot of those measures have already taken place.

But it becomes a much more formal measures in force to control people coming out of China on what we do with people coming back to let us say the U.

K.

What does it tell you when we learn that nobody has died outside China yet from this mirrors?

Well, I think that's very good news.

We we really don't know what the eventual mortality of this virus will be.

The report so far are quite low, about 3 to 5%.

But of course the situation is changing.

But we do think that many people will have a relative mild illness.

But clearly those that are older or have underlying conditions may be more at risk.

Will the virus be a fixed entity, or is it something could evolve within the outbreak of the disease?

Yeah, so this is a fairly new virus in people as far as we know, and it is quite likely to be changing quite rapidly, both in terms of thesis imp Tums it might cause, and also in its infectivity.

If we look at related viruses such as the SARS virus 20 years ago on the MERS cov virus, which is in the Middle East, SARS has disappeared.

It came and went very rapidly.

MERS cov is still there in the background, so it's very difficult to predict what will happen with this 11 can understand the humanitarian desire to bring everybody home.

That is a you know, a broad is a word not in charge, not Chinese.

But what is more difficult to to understand is whether it's actually a very good idea in terms of containing the disease.

Well, there has been a lot of debate about that.

I think the decision has been made and as a from my personal point of view, if I was one of those people, I'd be very pleased to be coming back.

It's a relatively small number of people being brought back under controlled conditions on coming back to a very old fashioned quarantine, which means observing them for the maximum possible incubation period on, then releasing them if they're no signs of infection, so so that a group of people are going to be very easy to identify and monitor.

But the idea of keeping, say, 200 people in one place in quarantine.

Surely perhaps those who don't have any sign of it on may never get.

It might be exposed now to getting it by having to be walled up with 200 other people.

You see what I mean that you're absolutely right.

But you could argue that they be under the same risk if they stayed in in Wuhan.

The I don't know the details of exactly how they're going to carry out the quarantine, but they'll be monitored, I'm sure at least twice a day for things like temperature and any symptoms, I presume that there will be a certain amount of isolation within what I understand is an old nursing home or something similar.

I don't know how much contact they will have with each other inside the quarantine facility.

I'll be medicated or to think about that.

We don't have any specific medication against this virus and we don't have a vaccine.

The normal thing would be just a monitor for symptoms on.

I would draw the distinction between quarantining people who might have been exposed to the virus on might develop symptoms.

This is completely different from isolating somebody that's actually got clinical disease on.

That's a different thing entirely.

So this is a precautionary measure which we have applied to many infections in the past very successfully.

You downplayed the importance off, declaring it kind of global at declaring this a global emergency.

But what is the significance of it if the w h o do go ahead and do it, But it has a few defect not just on health, but on trade and movement of people on.

Therefore, it's have immense significance to the countries that are involved on potentially to others where the infection may go, too.

So I wouldn't downplay that at all from the whole global view of things, not just from a medical point of view.

The World Health Organization has declared a global public health emergency over the Corona virus outbreak after the number of cases rose to more than 7800.

Health correspondent Victoria McDonald is with me, Yes, well, we have just heard from the Director General.

That was a decision that was had been expected.

But let's just listen to what he said.

We don't know what sort off damage this virus could do if it were to spread in a country with a weaker health system.

We must act now to help countries prepare for that possibility.

For all off this reasons, I'm declaring a public ALS emergency of international concern over the global outbreak off novel Colonna by Corona virus.

He was when it was odd to say this was not a vote of no confidence against China, and over the past week or so, he has Bean saying a great deal about how impressed he has bean with what China has done so far.

But there is a problem.

There are a number off cases now outside China, where it's been person to person contact.

That means those people haven't bean in China, and yet they have developed the virus.

Those numbers have grown.

We've just heard of another one in France.

We've just heard of another one in America in the past few hours.

What this means is not necessarily which it can do with some outbreaks, that there will be no interference with something like international travel.

But it does mean that they can call on more money and more coordination And yet in the funny way that has Bean a great deal of coordination already over this virus.

We have just heard recently to in the past few minutes that 150 people who are being flown back from Wu Han Britain's flown back from Wuhan will land at Brize Norton sometime tomorrow and that they will be taken to Arrow Park Hospital in the Wirral, where they will be quarantined for 14 days, staying and in nursing accommodation.
