That's bringing more seconds on the issue.

High was you've been looking into this forest, however BC.

Yes, I think face marks very much going to become part of many of our lives now in particular those countries where lockdowns are being lifted.

Now some countries have even passed laws making it illegal to leave the house without a mask.

Spain's taking a gentler approach.

Not everyone has the wear one, but if you're owns in Spain and you want to take public transport, he won't be allowed to get on without one.

This was the underground in Madrid this morning, and as you can see, Red Cross workers have been handing out mass to people who may need one.

This is Brussels.

Similar rules in place.

Police were stopping anyone without a mask on making them cover.

Well, we know France is to follow with similar rules when it's locked down disease next Monday, and the UK may also be following suit soon.

Remember what Boris Johnson said at the end of last week.

Well, I certainly agree with is that is part of coming out of the lock down.

I do think that face coverings will be useful both for epidemiological reasons, but also for giving people confidence that they can go back to work.

Now, if those of you watching in Europe wearing a face mask is likely to be a new experience, that's much less the case.

For those of you watching in Asia, where masks are much more common.

His Vincent Me from the BBC World Service, you might wonder why so many people Eurasian, where face coverings in Hong Kong, Taipei and Tokyo people wear face masks were going about their business.

His stories say the customs of wear face masks began in Japan in the early 20th century, but more recently, outbreaks of infectious diseases such Assassin 2003 encouraged people to cover their faces in public.

Now it is not always easy and comfortable to wear face cover in public, especially warm weather, but all the time people just get used to it.

There's no clear evidence, however, Eurasia that facemasks stop the virus from being transmitted between humans.

But many believe they will reduce the risks of catching the disease.

And that's why, since Corbyn, 19 was first reported in China last year, we have seen even more people in Asia where in face masks, maybe the perception.

But actually the science is a little bit different wearing masters, primarily advised because they're designed to stop people potentially spreading the virus is also, in some cases there to protect the individual.

And on that second point, some people say, Well, we don't want to do it They say they don't want to protect themselves.

And this has become a feature of protests against lock down measures, particularly in the U.

S.

You may well have seen.

This image has been widely shared online.

The sign reads, My body, my choice.

And as I'm sure you know, that's a slogan that's long been used in the abortion debate.

This protester there was in Texas and is obviously trying to use it to make a very different point.

The thing is, though, that facemask are really there to protect the wearer.

Scientists including the U.

K s Role Society, say the main purpose of face covering is to stop anyone who has the virus from spreading it toe.

Others well, let's hear from Eleanor Murray, an assistant professor of public health at Boston University, his years on what the mass can and can't do to stop the virus.

The scientific research on the use of masks for the general public to stop the spread of infectious disease is a little bit mixed, but mostly because we haven't really had a good opportunity or reason to study this question in the past.

Evidence that we do have does suggest that individuals who are infectious when they wear a mask can reduce their transmission to other people.

We also know that people with stars cuff too, can be infectious before they start to show symptoms.

And so this is why it might be a good idea for the general public to wear masks.

It's important to remember that a mask doesn't substitute for staying a good distance apart from other people, and that a mask, once it's up against your face, is now potential surface for contamination.

So you want to make sure to wash your hands well before and after putting on or taking off your mask to put on or take off your mask only by using the straps or elastics, and not by touching the face part.

And don't adjust your mask using the face piece of the mask while you're wearing it.

Once you put it on, tried to leave it alone.

And don't touch it until you're ready to take it off for the day.

When you're finished using your class mask for the day, you want to make sure to wash it in warm, soapy water, and this will be a good way to clean that mask and make sure that any infectious particles on the Basque are destroying before the next time you use it.

And he also had some advice for anyone wondering what sort of masked aware well to stop spreading the virus to others.

Ah, home made one made out of an old T shirt, for instance, she says, will work fine, but for protecting yourself from catching it, and particularly for anyone, work in health care.

Obviously, that's when you need a more sophisticated, properly produced mask to make sure it's keeping you safe.

And with that, it's bad to uber Beatles.
