Channel four News Q and A on the Corona virus or, as it's officially known, covert 19.

Now we know this is an international health emergency.

Cases seem to be increasing and spreading around the world.

But we also know that for a lot of you out there, there's a lot of fear.

We've asked you give us some questions and we're gonna now some of them to an expert on that is epidemiologist and by security expert Dr Ngoc Run.

So one of the questions that we get a lot, quite a popular question from a lot of people is.

Even though there are vaccine trials, clinical trials are in played right now.

Estimates say that we will probably have Ah vaccine within one year to 18 months.

And even though that sounds like a long time, that is quite fast if you think about the history of vaccine development, so that is reassuring.

But that's 18 months for us to be on our guard and to be aggressively fighting this Corona virus.

Why is that so quick to get that Mexico's that Because we've sort of advanced to a stage now we can get a vaccine that quickly, right?

It comes the Corona virus that causes that current virus is a family.

And so we've had other Corona virus diseases such as, Ah, the severe acute respiratory syndrome, which is stars Acela's, the Middle Eastern respiratory syndrome murders.

There has already been some research happening, so we're not starting from scratch, scratch per se, even though this novel coronavirus is novel with the cure aspect, you know, some people have mentioned you know, what does it tell us that some people have had a Corona virus that then recovered and they've got again?

Well, that's what we're still trying to learn.

We're trying to understand what happens when you have it and you build up antibodies against it, and obviously every every person's going to react somewhat differently.

I'm, of course, like a healthy 25 year old.

Um, it might be much easier for that person to fight off a re infection than somebody that is older that has existing disease with some people say to us.

So how can I tell the difference between the symptoms of a nasty cold or the flu on dhe covered?

I think that's a really good question, and right now the case definition.

So how scientists are describing in using, Um, like a set of, say, like principles to identify Corona virus is really beyond the symptoms of, you know, having a fever, having body aches, having a cough, which is president of cold and flu.

So have you traveled recently to anywhere that has had a cluster of of infections?

It has an outbreak, so of course it would be different areas in China, especially who Bay province.

But also right now we have ah cluster of outbreaks in northern Italy.

I mean, there's different places, so if there's a cluster there, that's part of the case definition.

One has someone in your family, been there.

Close contacts are the most important people in this situation.

While we have seen very few cases limited cases where they can't really say, you know, actually, I don't remember being next to anybody who have, who has been to China or any of these places where there's a community transmission while we while we don't have a lot of that that does exist.

And right now a lot of scientists are trying to figure out where they got that from, because because another concern from a lot of people seems to be that Is it possible to be infected and show no symptoms whatsoever?

So we have seen some of those cases again limited cases that are asymptomatic, so not showing any, um, any symptoms, that something that we're still looking at a TTE the moment.

I mean, I can't say what percentage because there's so many different populations studies going on right now, but for the most part it seems that people are actually presenting with symptoms, even if they're mild symptoms.

And, as you know, a majority of people who are contracted covert 19 actually exhibit mild symptoms.

And in terms of what we do know, trying to put it in perspective lets people don't know.

So what do we know if we want to try and compare this tow something like seasonal flu, Right?

So what we know is that it's transmissibility, so how easy it is to infect someone else.

It seems like it's similar to seasonal flu, and that means that it's relatively high.

Um, as far as its mortality or of its death rate, it seems like it's about 2% of the population who it seems like that we were still getting more data.

But about 2% of the population who contract cove it 19 are dying.

What we have seen in China, where we've had the majority of information because they've had thousands and thousands of people that have been tested on and observed, it seems that most people who contracted the mid 19 or between Colvin, 19 are between 30 years old and 69.

Most people who die from it are like around late sixties early seventies, um, as far a seasonal fruit flew in its mortality rate.

Seasonal flu has a less than 1% mortality rate, so more like 10.2% so covert 19 at 2% is higher in much higher actually, than a seasonal influenza.

This is not a pandemic yet, but it also said, this is not like any other influenza.

That means that this strain of Corona viruses nothing that we've seen before is that concerning?

I think it's concerning because we don't have any immunity to it.

You know, with seasonal flu, at least we have vaccines.

And like this year, the vaccine was quite effective.

It was about 44% for people who actually got the vaccine.

But what we do know, compared to other viruses that can try that that have respiratory illness or that cause respiratory illness, like what I said earlier about the stars and the murders.

Now, when you compare it to those diseases, it looks like it's much weaker.

So, for example, with MERS about 30% of people who contracted MERS died.

So the 30% mortality rate with stars about 10%.

Yeah, well, I guess some people are concerned that it's, you know, there are figures about sort of 60% of the population, 80% of population getting it.

That that you could see 60 to 80% of the population off of each country of the world getting this.

So I don't think that that is, that we're able to really confirm how many people are, What percentage of the world like.

In some ways, it is possible for many people to get this disease at the same time, but in other in other situations.

So if you even look a seasonal flu, um, everybody doesn't get seasonal flu at the same time.

So we have, like a flu period between maybe December and February or march to anywhere you are, and then we have another one that comes in the fall.

So we just you know, this was just discovered at the beginning of December, so we're waiting to see if it has that seasonality pattern as well, because I think it was Donald Trump who originally said There's another people talk about it that, you know, come the warmer weather.

This is something that we're hoping and that we're looking at.
