It depends on the seal, see below:



When you breathe in or out, if there is a good seal between the mask and your face, the air flow will be forced to go through the filter element. My understanding is that this will slow down the air sufficiently for the particles/droplets to become trapped.

Certainly without a good quality seal, you will inhale and exhale some air through gaps in the seal region, rather than through the filter element. High density (compared to air) particles/droplets which are ~1 micron (typically) and are already suspended in the air are excellent at following the air flow. There is no debate about this, it is well known that such particles/droplets, once suspended, follow air motion extremely well. So if there are any gaps in the seal, there is a risk you can inhale them, and also a risk you can exhale back into the atmosphere.

If you want to wear the mask as a means of preventing others from becoming infected, this is risky, at least for some masks. As the filter blocks particles/droplets, it can become more difficult to breathe through because the filter "clogs up". This idea that you can "clean" the disposable masks (and therefore allow you to reuse them) may not be true. I don't know how the masks are designed, but I believe the filter element of some of the masks may just be layers of fabric, so you may be able to clean the outer layer well enough but not the inside layers.

This idea that you "don't touch your face" makes sense in theory but in practice, you will still scratch an itch, rub your eyes (for half masks) and risk removing the mask incorrectly and therefore touching your face. You should not be using a mask for the sole intention to avoid touching your face. If this is someones motive, they are much better off just wearing latex/nitrile gloves.
Cheers for the detailed answer. Seems difficult to get a perfect seal on a mask, I guess if they catch/block even a single particle it's something.

Because making an enemy of footballers will take some focus off the disastrous job the government have done on the whole.
Yes.
Anyone but themselves.
And they know that millions of gullible people will focus on PL footballers.

A complete distraction. As usual...

Considering how unsanitary the conditions are that they live in and how closely they live I would expect them to have a better immune system. They are very heavy smokers though, which is going to have an effect definitely.
I pray everyday for this country tbh, either a miracle happens or a real carnage, nothing in between

Tories going into full blame Paul Pogba mode it seems.
Not defending the Tories in any way but nice to see that socialist principles do not extend to overpaid footballers when non playing members of staff in some PL clubs are already being put on furlough. I suppose next you will be saying that someone like Branson is quite entitled to protect his own wealth and put the burden of assisting his staff onto the government.

Of course it was a shallow remark for Hancock to say but he was quite right to say it. Anyone with a great deal of wealth should be extending a helping hand to those in real need.

All the neighbours out again!
I remember a lad when young who just had to be around people. He could not live without talking to people. So every day he would be over at my house in the summer. I was fed up with him coming over all the time.

Some people just go mad if they are not out and about.

I love being alone in contrast.

England:
VAT is a horrible tax (apart from its easy to collect), I hope not. Maybe a chance for a government to have a proper look at wealth taxes, even if initially on a one off basis. To be honest with the oil price crashing and more people not driving I don't know why Rishi hasn't stuck 10p a litre on the price of fuel for the next year.
I can definitely see it going up to 25%.

My sister got briefed today on how to prioritise patients for ventilators and all round help. She's in bits.

I mean I won't go into details as we can all guess, but feck me the people who still don't think this is a real bad situation....

Not quite sure that's the only issue to be honest. More or less as soon as the football was suspended, none playing staff, caterers etc were left without income, while footballers and management still took full salary. Its been heavily debated over the last few weeks on talksport that the clubs have not been acting morally in respects to the two tier treatment. The pfa and the fa have been as usual dragging their heels in regards to the situation which has led to individual managers and players having to take the lead rather than be led by the club.
Hancock was asked his opinion about it and gave his answer, i see nothing political about that

Introverts and Extroverts. It’s about where you get your energy from.

Some recharge by being sociable. Others recharge by being alone.

Sadly, some people aren’t always very forgiving of the latter.

A major hospital in East London. She's a head nurse and basically in charge of her particular unit.

What's also grim is they are a major trauma unit, but there's no testing at all and they have to treat every patient as if they have the virus.
Sorry to hear it, i think it shows just how close the peak is coming for London. Could be over the weekend or early Monday.

Public health England have today once again changed their guidelines for PPE . It's embarrassing how so many changes keep happening and a lot of it seems to be resource based

Your sister has my sympathy. I had to have a similar conversation with my wife. It wasn’t easy.

If you know who has the virus and who hasn't then you isolate those who do and thus prevent more people getting infected. A lot of people are asymptomatic so they could be spreading the virus without knowing, if you do know you're infected then you know to take measures which prevent others getting the virus.

What you are saying is great in theory but not sure how it works in a practical way specially with the country being in a lockdown anyway . If I got tested negative today and met you in the supermarket in the evening and you tested positive tomorrow then not sure how testing made any difference

What’s the logic in splitting by gender?

I assume he's leading the way by insisting that those in his own party take pay cuts and calling for the Tory party's millionaire/billionaire backers to contribute some of their vast wealth?

I've kept well away from discussing maybes about all of this, I've tried to keep clear of all the stats and figures and all that, so I'm not one to be dramatic and share whispers lightly.

But when you hear if from someone on the front line...well you share. When medical staff are being told the hard truth about who they can save and who they have to blatantly let die...I have nothing but total love and respect for these guys. Sadly, after all of this, we'll go back to taking them for granted all over the world.

Husband and wife teams are working around the 1 person per house by standing behind each other in a queue and then joining back up when they get inside the supermarket.

I had a mission to the supermarket today and some idiot family decided to bring their granny in a wheelchair too.

I see, cheers. Granny thing is madness, got to be a lack of education.

Can you share which hospital? My neighbour is a trauma surgery nurse and she has been extremely blase about this whole thing from the off. It has really been frustrating to me because of what I've read in here and my ability to at least read data enough to be able to see that this is serious. I'd like to be able to convince her of that but I reckon she'll get dragged into it anyway and see that this is for real.

We are by Whipp's Cross Hospital.

Matt Hancock can only answer the question posed to him. It's the journalists who are the ones obsessed about footballers being paid their high salaries.

It's easy to collect in some cases but easy to avoid in others. Put it up too high and we'll have a much bigger dishonest black economy which is the last thing we need on so many levels. It's a good tax when it's at a rate people are willing to pay but go above that and it's a horrible one, as you say. Wealth taxes, income taxes, petrol taxes.

The idea being you do it in a Singapore type way where there is enough testing to catch the person who goes into the supermarket before they get there. If you don't catch them you tandem it with contact tracing so you would be found as somebody who had contact with that person and warned you needed to go into isolation.

The latter would be seen as a problem with human rights here though as it involved an app on your phone using GPS to track your movements and warn you if you had been in contact with a person who tested positive. It's worked crazily well there though.

It won’t be business paying that then. It will be us all over again.
True, but when has "the little guy" never taken the brunt of problems?

As another poster pointed out, we had 17.5% vat before the crisis, and I bet everyone thought it would go back to that after a certain period of time - but nope, stuck at 20% and I'm guessing if we do go to 25/30% then we'll never see it reduce.

People pinning their hope on the big companies finally paying their fair share will be sadly disappointed, I dont mind paying for what I get (I'll be getting about £1200 a month during my furlough so £3600 in total - paid at the end of June) so it would be nice of the government tallied what everyone got and just spread that over the next 5-10 years worth of tax instead of blanket tax everyone, that way the NHS staff and other key workers wont be shafted (again).
