It depends what kind of mask. Proper respirator masks like N95 and FFP2 work very well. There are now very clear results that show that the main mode of transmission is respiratory aerosol.
As an example, this Lancet paper captures it well: ”Ten scientific reasons in support of airborne transmission of SARS-CoV-2”, The Lancet, 2021. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)00869-2/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6...
Numerous results have come out since.
I can’t find fault with the data or the investigation or the conclusion – I act according to this: We’re dealing with an airborne pathogen. Aerosolized.
Closed masks – respirator masks – N95/FFP2. These do work. Almost unreasonably well.
“Surgical masks” that gape at the sides do not protect well against aerosolized particles.
- pcmoney 5y agoMasks as used by 90% of the mask wearing population which is only 40%? Of the total population dont work well* If you feel like you should wear an N95 properly to be safe then you should do that. But let’s not pretend we can get everyone to properly wear N95s
- monksy 5y agoEven improper usage of N95s give much more protection than a surgical with a mask brace. https://www.cidrap.umn.edu/news-perspective/2021/10/commentary-what-can-masks-do-part-1-science-behind-covid-19-protection https://www.cidrap.umn.edu/news-perspective/2021/10/commenta...

- AnthonBerg 5y agoIndeed. It’s tragic.
