Henk Poley added,
The slope is lower for countries which went through the shock of SARS 17 years ago and have strong societal norms towards obeying authority. Why think masks are relevant?
Because from studies on nurses treating flu patients (same mode of transfer as SARS-CoV-2) the number of infections were divided by 5 if they wore mouth masks. Both surgical masks and P95 masks were as effective.
Also from studies of parents treating children with flu, where masks reduced infections by 75%. Surgical masks were only slightly less effective (N95 respirators may develop their full potential only when worn with professional training but are still very useful without it).
So the best I've got on this is https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30134-X/fulltext … which (a) agrees with you both on the carer setting but (b) notes the absence of evidence for broader usefulness [and (c) notes that absence of e ≠e of absence] Is this roughly the current state of knowledge?
Meta study SARS and masks, UK https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5779801/ … Masks against influenza, medical personell https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5705692/ … https://www.sciencedirect.com/science/article/pii/S0091743514000322 … https://www.ncbi.nlm.nih.gov/pubmed/31479137 Masks against influenza, householdshttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC2662657/ …
I am unaware of a single study that shows that masks increase the risk of infection (because they give a false sense of security or because they are used incorrectly, as it is stated in the WHO video).
"Oh shit, we don't have enough masks for the professionals" seems to be the only reason they say they are not effective now.
which, if they can find a more honest way to say it, is a fair reason to discourage purchase?
Yes, but not a reason to discourage at-risk populations, delivery and retail workers, bus drivers, airline employees etc. from wearing masks. Also, a reason to encourage people to ask for increasing supply, and even make their own masks in the meantime if necessary.
A single infected retail worker or TSA employee can easily infect hundreds of households. A single warehouse worker can easily infect hundreds of retail and delivery workers. Telling people that masks don't work is insane.
There is also the problem that you can at best only convince 60%-80% of the population to not buy masks in this way. To prevent that 20% of the people buy 100% of the existing supply, you have to ration the supply instead of appealing to consumers.
In The Netherlands we have at least 5 cases from a single sick bartender in Austria. There must be many more who went there for a pint after skiing.
Thankyou I shall contemplate, inwardly digest, and RT.
