16 were positive.

Eight of them have now been discharged from hospital.

But with more cases expected to emerge, the government is set to launch a new public health campaign.

Fears about the impact the virus could have on the global economy has caused markets to plunge today.

More on that in a moment.

But first is our health editor Que pin Another frustrating day for British tourists confined in quarantine at this Tenner Reef hotel on Italian visitor tested positive for the Corona virus on Monday.

There was confusion when the local health minister said 50 Britons who'd arrived since Monday were free to leave.

They seem to have decided not to, as advice from their travel agent on the Foreign Office was to stay put.

Meanwhile, apparent at this school in Derbyshire who had returned from Tenerife tested positive.

The school was closed for a deep clean.

A local GP practice also asked patients to stay away because of the case, one of two diagnosed in England today and tonight, confirmation by Northern Ireland health chiefs of the first case there the patient had traveled from northern Italy.

Public health staff here are no working rapidly to identify any contacts the patient has had with the aim off preventing further spread.

All of that has further fueled public interest in the virus and getting tested.

The N.

H s is expanding the options, including this drive thru facility.

She's just going to demonstrate what actually happens.

So she stays in the car, she winds down the window and then two members of the nursing team will come out to meet her.

One of them has got the full protective equipment on her colleague stands back a safer distance.

Erica, the senior nurse, shows information about the procedure on, then carries out nasal and throat swabs.

They're sent off for testing people referred here by N H s 111 If they don't have symptoms but need to self isolate, they get through 12 tests a day.

The aim is to roll out facilities like this across the country.

The N H s 111 help line will be expanded.

And if there are a lot more cases and HS leaders say hospitals will be able to cope, I know the N H s is busy and we're coming out of winter.

But we are well prepared.

Thio manage this sort of circumstance we do it every winter when we know we will see high rates of influenza, for instance, eso we have a blueprint to work on.

Certainly if you ask any trader from the city of London to Wall Street, we've seen yet again shark dropped in the in the prices of stocks, all of this being driven by investors who are basically pretty worried about what is happening with the Corona virus.

Over £150 billion has been wiped off the value of the foot in the last four days, and here on Wall Street, you've seen the Dow Jones Industrial basically just suffer its biggest points loss in history.

It also joins other market's slumping into a correction, which is a drop of more than 10% over a period of days on the price of oil continues to fall sharply.

What is happening is that investors are trying to do what everyone else is, and that is to predict what will happen next.

In Japan, where they're preparing for this summer's Olympics all state schools to close for a month in a bid to stop the further spread of the virus, the vast majority of the deaths in China have been in who obeyed the province where the outbreak began.

We do not have enough about that's available for for everyone.

I think things are are holding up better.

Right now, Wuhan shows what the virus can do to a health system.

The thousands of extra beds have begun to make a difference, but there is still a major challenges.

I'm not satisfactory with those mortality as dosing.

Immortality is really too high for patients with severe symptoms that it is even the mortality is even higher than stars.

That's the thing we should address right now.

This is Dr Share, dealing with one of those severe cases among thousands in Wuhan.

No city in the world, he says, would have enough specialist equipment to cope.

Even doctors have died, including Lee Wen liang, one of the first to try to warn about the dangers of the virus, only to be silenced by the police.
