We are continuing to monitor the outbreak of the mysterious new Corona virus tonight.

The number of confirmed cases in China keeps soaring nearly a week into the biggest quarantine in history, and another presumptive case has been identified here in Canada.

A man in British Columbia who is in his forties and regularly goes to China toe work as isolated himself and is waiting for test results.

There are two confirmed cases of the Corona virus in Ontario husband and wife, both in their fifties, who recently came back from Wuhan, the center of the outbreak.

The virus has now spread to Japan and Germany, and in both cases, authorities say, the people who are ill did not travel to China themselves.

But we're in contact with someone who had.

The German Ministry of Health now says four people were infected after attending a company training event last week with a colleague from Shanghai.

As many as 40 people may have come in contact with the woman in China.

There are now about 6000 confirmed cases, and at least 132 people have died, most of them in Wuhan, the U.

S.

And the UK, or sending passenger planes to Wuhan to repatriate their citizens.

There are 250 Canadians registered in the region.

Foreign Affairs says 126 have contacted the consulate asking for help to get home, but at this point Canada is not sending a plane to get them.

We're trying to contact everyone, assess their specific needs for assisted repatriation, were at the same time consulting with their allies and looking at the different options that people are considering.

The U.

S.

And the UK have now upgraded their travel warnings, advising citizens to avoid non essential travel to all of mainland China, and several airlines are cutting back on flights to China.

At this point, Canada has not expanded its travel warning and it's still advising people to avoid the Wuhan region and who Bay Province Redman Shannon has our top story tonight, as if further evidence were needed that these are extraordinary times.

Yang Yang Hong Kong leader Carrie Lam, wearing a face mask on item she banned last year during the pro democracy protests.

Lamb, announcing that visitor permits and most travel from the mainland will be limited after Thursday night.

Hong Kongers like this man think it's too little, too late.

Eight cases have already been reported in Hong Kong.

In Beijing, the head of the World Health Organization met with Chinese President Xi Jinping.

They agreed for a W H O team to join the 6000 Chinese medical staff who've been sent to the affected region.

The organization says the emergency remains confined to China, but the global risk is high.

So far, it's going back with travelers, too, to foreign countries where there's the home country of somebody who are travelers such it's not widely spreading outside of China.

But again we have to be prepared for in case it would.

In Wu Han state TV shows the much hyped building of a special new hospital, some prefabricated rooms already in place.

Most people living in the city remain holed up at home money, shouting encouragement to each other from apartment windows.

We're not really sure if they're reporting the truth, like if they're under reporting, the actual numbers are, I think, just like not knowing what's actually going on and how long it's gonna last like that's more on cities near the affected WHO.

Bay Province are increasing checks to anyone arriving those with high temperatures sent to hospital immediately on more than 1000 kilometers away in Beijing, some empty shelves and long lineups as the first death from the virus is confirmed in the capital.

Redman Shannon Global News London Now, to what we know about the cases here in Canada, here's Heather your ex West.

Health officials say Canada's third presumed case of novel Corona virus did everything right.

This is a gentleman who was well aware of what was going on in China, and when he returned, he went home and he voluntary self isolated.

The man had recently traveled to Wuhan, China, but did not have any symptoms until more than 24 hours after he returned.

This person was not symptomatic on his flight.

There's no risk to people who aren't who were in contact with somebody with no symptoms.

But there are questions within the global medical community around whether or not that statement is true.

Normally, with a corona virus, we Seymour viral shedding and more transmission when a person is more symptomatic, China has reported there may be evidence of asymptomatic transmission all of these questions must and will be answered in order to provide a proper risk assessment.

The Chinese Embassy in Canada is advising all Chinese nationals returning from Wuhan to isolate themselves for 14 days at home.

So far, all cases across North America have been traced back to China.

The coming days and weeks are likely to bring more confirmed cases here and around the world, including the possibility of some person to person spread.

Studies on the new Corona virus show that, on average, one sick person can infect between 1.5 and 3.5 other people.

That makes it a bit more infectious than most seasonal flu strains, in which sick people can infect between one and 1.5 others, but less infectious than SARS, which spreads from one, 2225 others.

It's why public health officials are doing all they can to prevent an outbreak, isolating and testing anyone who traveled to Hubei Province and has now become ill.

We need to be very vigilant.

There are people who have traveled, who are here, who might be incubating this virus who might be becoming sick in the next couple of weeks.

And that's why it's so critical that we maintain our focus because the success of their efforts will be measured in the days ahead.

Heather your Ex West Global News Calgary As the story keeps evolving, there are many questions, and it's important to balance fear with facts.

So to help us do that, I'm joined again by Dr Michael Garden.

He's an infectious disease specialist and chief of staff at Humber River Hospital in Toronto.

Dr.

Garden let's start with the news of the confirmed cases in Germany and Japan.

In both cases, the people had not traveled to China.

The man in Germany was in contact with a woman who had come from Wuhan but apparently did not have any symptoms until she was on the flight back there.

Does that raise alarm bells for you about the virus spreading and possibly spreading when people don't have symptoms?

Well, you know, certainly seeing cases that are occurring in in places where this has been imported, where somebody who traveled has given it to somebody else.

We've been We've been looking for that the whole time along, so that isn't a big surprise.

The issue here is how contagious is this virus when people have mild symptoms and honestly, it's really hard to sort of set worldwide policy on one case, right?

So we really need to be cautious, saying that the virus is highly infectious in that setting, typically with viruses, people are mildly contagious if they have minimal symptoms and they're much more contagious if they have a lot of symptoms.

So it's it's possible.

It can certainly transmit if people have mild disease or maybe even no symptoms, but it's certainly less likely than if they're sick.

So is it too early than to be definitive about the transmissibility of this virus when people are contagious and how exactly it's spreading?

Absolutely.

I mean, we need to take a step back.

I mean, typically with other viruses.

What we've done is we've looked at people where we have a good idea when they got infected and then we're doing serial swapping on them to see at what point they start to shed the virus, at what point that they start to develop symptoms.

None of that has been done with this particular virus, so I think we are too early to get very definitive about how it is transmitted.

If we take a big step back, though, and look at the epidemiology.

The spread seems to be similar to what we saw during SARS, which is that people who are sick are the most likely ones who are actually spreading it well, given the unknowns and given what you just said, should people who have been to the Wuhan region bee style self isolating as a precaution right now that's not recommended.

I mean, it's a very good question right now.

What we're looking at is people who have who have symptoms.

That may change over time, But you can imagine if we start to broaden that case definition.

We're now anybody who comes from Wuhan is isolated or take it even further.

A lot of calls I've been getting today is why are we isolating every person who has even been in China?

You can imagine that very quickly overwhelms the public health system.

So early on, we have to be very sort of surgical on what we're doing, and if necessary, we start to move out.

We have to remember the area that's been locked down.

We're talking 35 some 1,000,000 people so the vast majority of people from that region do not have this virus.

Okay, We'll watch and wait and hopefully speak with you again.

Dr.

Garden.

Thank you.

Thanks for having me.
