Almost all of them are in Who Bay Province, where this outbreak began.

And as you can see from this graphic, there's been a huge spike in the number of cases to There are now more than 48,000 in who bay that's up 15,000.

And the upward shift is in part because of a broader definition of the virus and how it's being diagnosed.

Here's the World Health Organization on that.

Crucially, we understand that most of these cases relate to a period going back over days and weeks on our retrospectively reported as cases of since, sometimes back to the beginning of the outbreak itself.

Well, here, the number of cases in China going up and up, we're now close to 60,000.

The death toll in China is over 1350 but in reality that figure is higher.

Those who die at home are not being counted in.

Official figures on the BBC knows from having spoken to people and woman.

That's what people are choosing to do.

Here's a quote from not school on the BBC news website.

We'd rather die at home than go to quarantine on.

While this crisis is escalating, there's increasing pressure on the authorities to senior officials and who bay have now bean sacks.

Let's get more on this from Stephen MacDonald in Beijing Now as to whether or not the dismissal of those two senior Communist Party officials on this very day, that is a coincidence not, I'm not sure, but it doesn't look good for them.

I mean, the Who Bay Party secretary and the party secretary as well for Wuhan city of both being removed.

But somebody had to take a fall for this.

I mean, there's a lot of public anger.

Lot could have been done to bring this under control before millions of people left Wuhan.

And in fact, there's a lot of evidence showing that in those early days they tried to stop information getting out.

And here's Celia hatin on who could replace those officials.

The two new men in place and in who 1,000,000,000 Wuhan are both loyalists to see Jean Ping, especially the man in charge of the province single.

He comes from Shanghai.

Now he's a man known for tough security measures, but also last year he implemented a citywide recycling program in Shanghai.

Now I know that probably doesn't sound that impressive.

But in a city of 23 million, almost overnight, to get all of those people to suddenly follow new rules, he managed to pull it off.

That program is still in place and is being carried out across China.

So here's a man who is known for security and implementing really big projects overnight while all those skills are gonna be needed, because scientists and officials are trying to work together to fast fashion an effective response for more on that This is David Heymann, who directed the Wh ose response to the SARS virus in 2003.

We're all concerned about what we don't know.

We know so far what's happening and what we can see.

But what we don't know is the real potential of this virus.

Whether or not this eventually could become a disease endemic in humans like T B, influenza or others, because influenza also comes from animals into humans and it sometimes becomes a permanent resident.

Another important detail is that we know that this virus is not spreading particularly quickly outside of China.

Is David Heymann again?

Well, certainly it spread throughout China, and China is making every effort they can in the way that they do best to stop the disease.

What's important, though, is those 24 sites outside of China and also the cruise ships.

That's where the information about how severe the diseases we really come from, because the patients here are being monitored very closely, as are their contacts.

And we're learning a lot as we see what happens in these situations, which hopefully will lock down the disease in these countries and not permitted to spread further well.

The shift our focus from China further south to Vietnam because a town in the far north of Vietnam of about 10,000 people is now under quarantine following five cases of the virus.

This is one image we have of the checkpoints that have been set up on the outskirts of the town from Vietnam within shift to Cambodia because that U.

S cruise ship, which had been turned away by five countries, has finally being allowed to dock.

Here it is.

It spent two weeks at sea searching for somewhere to stop, despite the fact there are no confirmed cases on board on.

Here's an image that we saw online of passengers cheering and clinking glasses as they finally arrived in port and while they might set a break, But for the moment, they're still gonna have to remain on board as a precautionary measure.

Next, we have to talk about perhaps the cruise ship that's been getting the most attention.

The Diamond Princess currently stuck in Yokohama in Japan.

It has over 3.5 1000 people on board, and no one's getting off.

That's because awful those people at least 200 passengers and crew are infected.

Rupert Wingfield Hayes is just beside it.

So the number of infections on board the Diamond Princess behind me here in Yokohama has again jumped today.

44 new cases confirmed today that followed 39 cases yesterday, and that brings the total number of infections from the ship to a 218.

And that means as we know now, this is now the single biggest outbreak off the cove in 19 virus anywhere outside mainland China.

The Japanese government has made a small concession to the criticism that has been building off.

It's the way that it's handling this outbreak.

They've said that very elderly people over the age of 80 will be allowed to disembark if they have underlying health conditions or if they're in one of those inside cabins that don't have any outside windows or balconies.

So expect to see that start happening maybe tonight or on Friday.

But there are many questions that remain.

First of all, obviously is.

Are infections still taking place?

Is the virus still circulating around the ship?

No one really knows.

On the other big question is why.

Still, as the Japanese government not managed to test all of the passengers and crew on board now?

Two weeks ago, a group of British nationals were evacuated from Wuhan in China on they've spent two weeks at a hospital in northwest England.

While now all 83 of them have been released, you can see one of them celebrating there.

They've all been given the all clear Fiona Trot was there as they left.

So strange to eat is being for them evacuated from China, coming here to the Wirral, signing a form agreeing to be quarantined wondering, Do I have the virus and then getting used to the confinement itself?

One man left here earlier, shouting, I'm free!

So there is relief here this afternoon.

But also what's very clear is that all of the 83 people here are very, very grateful to the NHS staff with care they have seen.

Well, the man celebrating his release here is Matt Raw and he's being giving his reaction to the BBC.

It is lovely, absolutely lovely to be out.

And I'll no doubt going out for a for a pint a little bit later on.

Well, who would blame them?

Not that Matt is complaining about his ordeal.

Ocean say, I would say that 99.9% of us if not 100% of us are really happy to have been here.

We're very grateful to have been here.

You know, the last thing that anyone of us would have wanted is to have passed that virus on if we were infected to pass it on to somebody else.

You have to live with that.

You know, if somebody does get sick from it on dies, way to have to live with that for knowledge for the rest of our lives.

And of course, that's not who we are way.

Most of us.

We travel a lot.

We travel extensively on you know, there are risks associated with that.

So we do take ourselves seriously.

Aceh expats.

And of course we want to be as responsible as possible.

And if that means staying in quarantine for a couple of weeks, so be it.
