Face Masks
It appears that the government has now decided that face masks have some efficacy and are suggesting it would be a condition when lock down ends for workers to wear them and when using Public Transport
Our London Mayor is now saying he will INSIST the public wear them. About 10 days ago his LT workers were crying out for them and he told them,at the time, they were not necessary but gave them gloves instead.

Quick back-of-the-envelope calculation suggests that merely standing an extra foot away above the 2 metre recommendations might make as much as a 25% difference in viral exposure*. Clearly a top-of-the-range mask, if properly fitted, would beat that, but it's hard to assess what happens if people worse face masks incorrectly fitted, or not made of the proper material, and then ended up standing closer more often.
These are clearly difficult calls, though, and I'll obviously defer to government advice as and when it comes, or to any study that demonstrates that my pessimism here is unfounded.
*Optimistic application of inverse square law, which seems reasonable here.

no - - - I did
luckily no one ever reads my posts
so they also missed we have known this for at least 50 y and more like a hundred
that their uselessness was confirmed by 'cough' plates (*) 50 y ago
and there is nothing to suppose that if they dont stop Bacteria either way that they will stop smaller viruses
in the fact the evidence supports they wont
In the TB in aircraft case onlhy those doughnutting the infected case were infected ( 60% chance) and the rest was nil. None by the AC.
radio 4 - this am - "we think 6% infect someone just before they get ill - so masks may help" - er er - you have to show that the 6% is reduced by masks and they didnt
such is the standard of er 'scientific' debate at present
Lucky it isnt important ( doesnt make a difference either way)
(*) cough plates - some modern Aber is bound to quip ex parte - "foo what - you cough in dem or sumfing!" - yes that is exactly what you do. and find that putting a mask in the way doesnt make a ha' po'rth of difference )

jim; "I may be mistaken about this but I'm fairly sure that this is a decision that would be reached because of political pressure more than anything. " - indeed, like many things governments do they are more about appeasing media etc than actual reason and logic. The general public are thick as *** but they have the vote, thus governments must throw a bone occasionally.
Also, for clarification, the calculation above is about your chances of exposure; it ignores the effect of a mask on reducing transmission from someone coughing into one -- although, again, if improperly fitted it might not make much of a difference and might increase the risk if people assume that the mask they're wearing is enough to stop it and so take shortcuts in other areas.
// an extra foot away above the 2 metre recommendations might make as much as a 25% difference in viral exposure*. //
we construct a sphere surface ( foot ball to you proles who have got down to here) and recollect that the surface area were were taught at age 12 is 4pir squared gettiing 48 sq m - so the goo is down to
spread over that and is down therefore to 2%
and if you are trying to affect 6% see above readio 4 this am
then the effect is down to 2% of 6% which is peanuts - 0.1%
as I said doesnt matter either way
or to put it as the average ABer may comprenny - " no way hoe-say!" - looky - three word sentence there !
foo ! I am not having you design an atomic bomb (*)
(*) joke ! joke!
Because 2 m is 6 ft in old units - andleads to attrition of 50 times or down to 2% - it is the limit for
aircraft interference
ECG interference
magnetic field in a hi power scanner ( 2000 Gauss surfacr)
X rays
CAT scanner - radioactive scans
same calculation - different uses - that surely is the advantgage of maff innit?

wh thank god ( deo gratias! o lordy lordy) we can - see my entries passim
same calc therefore reinforces social distancing as well as refutes the use of masks
Hey I luv maff - one calc - 1+1=2 or sumfing
and then reuse it 500 000 times - and charge each time if you can

Most experts seem to agree that wearing a face mask can stop some virus-laden droplets expelled into the air when a person coughs, sneezes or even just breathes out, which are thought to be a main carrier of the virus. Some experts say that the droplets can travel up to 12 metres and that masks are more effective than the social distancing measures we have now.
A mask, if worn properly, should stop a person touching their nose and mouth while wearing it. Unfortunately though, many don’t wear them properly.
