In this video, we're gonna look at each of those responses to Corona virus and see what's happened when they're being used.

Covert 19 has brought countries to a standstill, and they've all responded in different ways.

We saw a lot down in Wuhan, in China.

Now, countless others have done the same.

Italy, Spain, France.

Cities like here in London have called on people to socially distance on work from home, which is why I'm talking to you from my bedroom.

Now why the government's taking these measures.

The main thing is flattening the curve.

What we need to do is flattened that down flat in the curve, flattening.

Why do you want to flatten the curve?

That's the idea that in fighting this pandemic, we need to slow the rate of infections to give hospitals the chance to deal with patients without being overwhelmed, as well as giving us more time to find remedies and vaccines.

Now, while everyone agrees from the need to flatten the curve, how we get there has been up to debate.

So let's take a look now one of the earliest methods to implement this social distancing.

Now virus like Covert 19 could be spread when people with it have close sustained contempt with others who do not yet have it.

So social distancing is about trying to stop the chances of that happening.

So that's not just hanging out with people with device.

It's cutting down on a LL.

Non essential social interactions as well is not using public transport one possible.

I'm working from home like me right now.

It's also about avoiding large and small gatherings.

Germany recently said there should be no gatherings of more than two people.

That's why in places like here in London, clubs, restaurants, pubs, leisure centers have been closed, social distancing is implemented Once public health officials recognize that the disease is going to spread.

It is here.

It's going to spread.

But there are actions that we can take in order to reduce the rate at which it spreads.

Social distancing is a tried and true public health intervention, given that social distancing is an agreeable method helping stem the spread.

That's why some experts criticized countries like the U.

K for not calling for social distancing.

Earlier you case chief science officer said that it wanted to time things correctly and over the danger in moving too quickly.

So the timing is critical, and that's true across all of the interventions we've looked at.

That's why this is a package of things that need to happen at the right time.

On in the right phrasing, however, the U K government switched its path a few days later as new modeling show that drastic suppression measures like social distancing would cut deaths to tens of thousands, rather that hundreds of thousands.

For that to happen, the modeling said all households needed to reduce contact outside the house, school or work place by 75%.

But there's still a lot of criticism that social distancing is not being a deer, too.

Look at Bondi Beach in Sydney, after Australians were told to social distance it was still packed.

The beach did eventually close after scenes like these.

If the community does not comply, well, then this is going to become the new norm.

So what happens when you make this type of thing mandatory rather than advisory?

One step further than social distancing is locking down an entire city or even country?

That's what we first saw in Wuhan on January 23rd where the Corona virus was first recorded.

China put people in the region of who bay home to nearly 60 million people under strict quarantine and travel was restricted, The W H O said it was a move unprecedented in public history.

What does that mean?

Well in woo handle public transport, including buses, railways, flights, ferry service is were suspended.

Residents were not allowed to leave the city without permission.

In Italy, we saw the same thing with 60 million people told to stay at home, where possible residents can only go outside due to an urgent need like buying necessities on are expected to carry a form justifying their reason for travel.

They face a fine, if not France also did the same on March 16th issuing a strict 15 day look.

And the UK, after a week of asking people to socially distance, enforce their measures with a three week locked down.

If you don't follow the rules, the police will have the powers to enforce them, including through fines on dispersing gathered.

Given lots of countries are doing this.

It seems this is an agreed upon way to tackle the spread of the virus.

However, there are issues.

Firstly, Italy saw rises and deaths in cases after the lock down, so that raises the question of how effective it is.

Some commentators point out that Italy court enforce is locked down in the same ways that an authoritarian regime like China can, with a number of cases from inside the country dramatically reduced over the weeks.

Yet Bruce Aylward of the W.

H.

O said that China stemmed.

The virus is spread by rapidly testing people, placing those confirmed or suspected to have it in a media isolation and then quarantining those who had close contact with that person.

For 14 days.

Population knew what it was looking for and they knew what this disease was.

They knew where to go to get tested, and they could be isolated and taken care of very, very quickly.

People were part of this solution.

They were the surveillance system.

And what worries me always matters.

Everyone starts with what we can do.

A China did, and I said, Why not?

They said, Well, we can't lock down a whole city Nice.

Well, China didn't either.

They have thousands and thousands of city thing locked down a few which were had really gotten out of control.

And that's where we come on to ensuring everyone gets tested.

The W.

H.

O has always held up South Korea as an example of how to tackle the spread of the Corona virus.

A month ago, the republic off Korea was faced with accelerating community transmission, but it didn't surrender.

It's developed an innovative testing strategy.

It did exhaustive contact tracing South Korea very quickly developed a test, immediately began testing thousands and 1000 people.

They could do 20,000 in a day, even testing those who do not have symptoms using drive thru centers as well as novel facilities like this sort of phone box drop in outside a hospital and soul that allows anyone to take tests without coming into contact with Dr Who's the Asshole 100.

That's all, she wrote.

Could I just tell my mother I don't want bail?

South Korea may testing free and available to all in quarantine those who had the virus.

One infectious disease expert told Science magazine that South Korea's example showed that quote contact tracing is also very influential in epidemic control as his case fascination, basically what Bruce Elwood from the W.

H.

O was saying earlier.

But countries like South Korea and China also used APS to monitor the spread of the virus, the ability to know who has the virus and look at who have come into contact with.

So how did those APs work?

Here's a little explanation here.

Subject A has the Corona virus but doesn't yet know it or show any symptoms in their day to day life.

If they come into contact with other people at home, on public transport or even at work, when their symptoms begin to show, they can request a test and if it's positive or the people they interacted with our immediately notified by the act and told to self isolate and get tested themselves the places that visited our then decontaminated.

Of course, this raises the issue of the invasion of privacy on us entering a sort of big brother world.

But is that worth it when trying to fight this virus?

It's about using a 24 21st century technology to implement age old principles of epidemiology to rapidly instantaneously identify those people at risk themselves and those people at risk of passing on the virus to other people things like social distancing lockdowns about suppression, which aims to reverse epidemic growth.

There was a lot of discussion about the concept of herd immunity after Sir Patrick Balance said this.

It's not possible to stop everybody getting it.

And it's also actually not desirable because you want some immunity in the population.

We need to have immunity to protect ourselves from this in the future.

He talked about 60% of the population in the UK some 40 million people catching the virus to get towards this herd immunity.

That herd immunity concept is the idea that if enough people become immune to the illness in this case because there is no vaccine contract the virus on recover the Corona virus can no longer spread.

Basically, the more people you meet who are resistant to the infection, the less likely the illness has to infect someone who is susceptible.

After a while, the virus will not be able to infect enough people to sustain itself in a population.

However, that approach was criticized, including from one of China's main respiratory specialist Hold your the board on Gold digger so wait a GT GT 20 pieces.

Certainly we still don't know if people catch.

The Corona virus will become immune for life afterwards, and it's not clear whether people could become infected again, or whether the disease will behave like flew in the future.

Mutate into new strains to which people are not immune.

And it's worth remembering amidst all this that people here are changing their habits to help tackle this virus.

A new survey by Imperial showed that more than half of the population are avoiding crowded areas in 83% are washing their hands more frequently.

We've seen a range of responses from different countries.

As this outbreak has spread, China was first, and many have begun to follow their example with social distancing on lockdowns.

Yet the message from the W.

H O has always been that that by itself cannot work.

It needs to be backed up by testing, testing, testing to ensure that we can monitor how the virus is being spread and stop those who might not even know they have it to stop actually spreading it.

While we're in an interconnected world, nations are still choosing their own pathway when it comes to tackling this virus, and that can cause you some confusion or mixed messages.

As you see some countries take different measures at different times to your phone, let us know how you've been dealing with the response by your government in your country.

In the comments below, make sure you wash your hands, keep your distance and stay safe.
