I'm not sure why Naomi's thread on Face Masks has been closed but I was going to add that I agree with Naomi that there is a case for wearing one in supermarkets (and of course on trains, in taxis and even when passing someone on a narrow pavement), especially as some have said the 2m figure is not necessarily sufficient (eg if someone sneezes) and perhaps should be up to 8m. ) But although it can help it's certainly not guaranteed to protect you- it should really be supplemented by eye protection and complete face/head covering and gloves- and the masks need to be changed fairly frequently

// that I agree with Naomi that there is a case for wearing one in supermarkets//

no the evidence is that they dont work - we have known this for fifty years - OK they do if you use them as hankies or bandanas ( to rob banks of course)

as for limiting infection - forget it

oh and there is a good U tube viddie of making one youself
ply or crease a paper towel - two staples and staple two rubber band to the towel

hang on ears
// But although it can help it's certainly not guaranteed to protect you- it should really be supplemented by eye protection and complete face/head covering and gloves-//

what for going into supermarkets?
who has been peddling this rubbish ? - someone has been running their mouth as usual and guying the impressionable and credulous

luckily AB supports free speech so the most awful cobblers
can be promulgated with a straight face ! - I mean read some of the other threads !
Hi FF !
as you can see - some of the advice you have swallowed ( hi Andie!) doesnt ADD up!

Seems logical to me that someone wearing a mask in a supermarket wouldn't cough the virus as far as someone not wearing one. Probably wouldn't cough as much of it out in the air either.

Hi PP.
I was trying (but clearly not clearly enough) that a mask on its own is of limited benefit as a way of avoiding infection from someone who coughs/breathes/sprays while talking close to you - limited because at best it can stop droplets going straight up your nose- so what you'd really need is to wear eye protection and complete head protection and gloves since you want to stop droplets getting in your eyes and onto your face and hands.

After all, that's what they do in hospitals- they wear proper PPE- or at least they want to if they can get it.

To say "no the evidence is that they dont work - we have known this for fifty years" begs the question why NHS staff and carers are demanding PPE including masks
Masks are also very handy as they can be discarded on a whim onto the street, into a hedge.or over a wall so no need to look for a suitable bin.
Apparently

I have noticed on my travels around our larger towns and cities that masks are most in evidence in areas known for substance abuse.
It's as if the zombies are desperate to hang on for one last bender if this ever ends.

Yes, that's because they have become a bit of a fashion statement among the youths who drive fast cars and meet up to sniff their N2O canisters and use other substances before zooming off.
The NHS want them because, for a short period of time, they provide SOME protection. They need a lot because they should be changed frequently.
Question Author
Yes, Zacs. I said the same thing about 30 minutes ago. For the record I've no intention of using them- far better to avoid any situations where you might be at risk (unless you are a carer/NHS worker)- but if you need to pop to the local shop I don't see any harm in wearing one- might have a small benefit to others and a tiny benefit to yourself if you follow the same practices NHS staff follow
// Seems logical to me that someone//
and zen we do the experiments

and the experiments were done with cough plates (!)
what?
petri dishes wiv agar and red stuff ( culture medium)
and you cough at them wiv an wivvart masks - and .....

the results are the same which in experimental speak
is - they dont work (*)

why are theydemansing moon suits in Hospital - they work in a controlled envirnoment - clean hands gloves etc

(*) Lewis Wolpert nobel winner - had a wonderful phrase about himself - my life ( remember he godda Nobel prize ) is characterised by first class ideas and second class experimentation


Hey did any one catch the interview with Sir Paul Nurse PRS ( yup pres of the Royal society ) wh said - my labs and many others can do PCR 24 h a day and we asked if they needed our expertise

and the interview with paul cosford - director of PHE ( the govt testing lab) -oh god do you have any idea of what my life is like?
over the last week or so
you get what you pay for - boys and girls

Hi FF again
// They need a lot because they should be changed frequently.//
yeah I didnt want to cover how long they work for if they ever do

( 20 mins yes ,mins as in a third of an hour) at best
so long as you dont - - - gob or spit
ff, the only harm could be preventing NHS from getting them.
does anyone mind if I er point out ( to a maff master, Hi FF!)

that masks dont work - yeah so why do the health staff demand them?
is a howling non sequitur

I didnt wear a mask for twenty y and they were unable to proceed against me ( on the grounds of obvious danger to public health) because - all parties knew there wasnt any

[clearly work place specific - but I had worked at Porton so anyone saying but you MUST know the risks - - - got an instant lecturette on the subject until they - - - BEGGED for mercy!]
Question Author
20 minutes. Just long enough to nip out to the corner shop/Tesco express for an essential pint of milk/bar of soap then and wash hands thoroughly again on getting home before removing it and discarding it.
Question Author
Maybe wearing one in public (apart from hospitals/carehomes) should be an offence then PP in order to discourage the publicfrom buying up masks that the NHS needs
//the results are the same which in experimental speak

Well you didn't do the right tests then did you? Try blowing a candle out while wearing a mask and see how far away you are effective. These viruses are propelled through the air they don't float through the air, and if you affect the force of propulsion you affect the distance they will travel. Medical students!
Also, PP, hard to believe I know, but some of the virus a person coughs out will get stuck in their own mask.
// Well you didn't do the right tests then did you?//

oh dear you clearly need the mini lecturette on the uselessness of masks until you beg for Mercy !

I like the idea of going on doing experiments until you get the result you want - soviet science there !

or design different experiment until you get the results you want

or just make them up - [o god that has been done before]

In the jumbled up science mess on the Beeb where the poor hackette was completely at sea with the two tests - antigen or antibody, - she then turned to sneezing....to be fair, she cd count to - two - like a lot of people on AB

nice atchoo in slow motioni and silhouetter and it splatters everywhere - and then of course
you expect the second film to show the mask and it all goes splat inside the mask

it doesnt - they didnt do one - they just wanted air time
and to be fair again ( not like me at all) they did say well put a mask in the way and it MUST interfere with some gob and spit

Well you didn't do the right tests then did you?
a mask is a mask is a mask
and a cough place is a cough place is a cough plate

the right test - - - would be using your gob throwing muvva in law who can drench a room if she puts her mind to it?
Are you drunk, Peter?

You really need to get yourself more acquainted with tests that have been done on masks, and not rely on those done with your mother-in-law. Here's the results of one, but I am sure there are many more available.

You could also use some common sense.

PP- it seems to me medical opinion is shifting. There are medical experts who do not seem to share your view that they are a waste of time.
Example here https://www.theguardian.com/world/2020/apr/02/face-masks-coronavirus-covid-19-public
Another discussion here
https://www.cbsnews.com/news/wear-face-masks-coronavirus-public-experts/
I saw some professor or something similar in UK saying today there is a case now for the public to wear them.
They also say though that scarves or other face coverings can be just as effective for the public.
I think the tide of opinion may be changing and WHO may review their guidance.
Maybe we should revisit this topic in a week or so
