Of course masks work well at protecting you - why do you think people wear masks when exposed to dust?
The problem is that you can't wear it when you eat, and who does one eat with? Family, including children, who are prime infectors.
The great lie here in Switzerland has been to pretend that kids don't get ill and don't infect others, to keep schools open (without any attempt at e.g. air filtration) to keep people working (because the prime function of school here seems to be daycare, to free both parents to go to work)
- zero-sharp 2y ago>Of course masks work well at protecting you - why do you think people wear masks when exposed to dust? Is that really it? That's all you need to conclude masks are effective at preventing the spread of airborne disease?
- aredox 2y agoNo, there is plenty of experiments and analysis comparing protection from the "emitter" and protection for the "receptor" Mechanically, masks fit better when one inhales than when one exhales.
- zero-sharp 2y agoYou're aware that there are studies specifically trying to find out how well masks work at reducing the spread of covid, yes? https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD006207.pub6/full https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD... I wonder why we're studying this...
- taylodl 2y agoOver 100 years of medical use helps, too. You know, the idea of using masks to prevent the spread of infectious disease isn't exactly a new idea and is widely employed by medical staff every single day.
- mike_hearn 2y agoMasks are worn by surgeons to protect the patient in case spittle drops into them whilst the surgeons lean over them. It isn't to stop the spread of respiratory illness, at which they are completely ineffective and always have been.
- taylodl 2y agoYou do know that the surgical theater isn't the only place masks are used, right?
- telotortium 2y agoMy impression of mask effectiveness for aerosolized illnesses like COVID (it doesn't spread primarily through spittle, unlike what a lot of public health authorities assumed early on in the pandemic when the initial mask recommendations were made), after reading the arguments on both sides during the pandemic, is that they can be usefully analogized to birth control methods: - Surgical masks: douching after sex. Probably has some small effectiveness compared to doing nothing, but shouldn't be considered as a serious method to prevent propagation. - N95-level masks to prevent transmission: coitus interruptus. Definitely effective, but also almost impossible to use at anything resembling 100% effectiveness. With coitus interruptus, pre-ejaculate and general inability to precisely control ejaculation mean the method will assuredly fail after a while. Analogously, N95 masks would probably significantly reduce transmission if everyone used them, although probably not to 0. But outside of hospitals, compliance is probably not strong enough to significantly affect the progress of an infection wave. - N95-level masks to protect against infection (including masks with vents): condoms. Almost 100% effective if used perfectly, but can easily still mess it up on occasion. N95 effectiveness is much worse than condoms in practice outside of hospitals because masks have to be worn for the majority of the day, unlike condoms, which are only worn during the sex act itself. - Abstinence: staying away from any carriers. Unlike with sex, almost impossible to do for a contagious respiratory cold-like pandemic like COVID.

- Workaccount2 2y agoPeople do not wear masks correctly to withstand being around sick people. This was abundantly clear during the pandemic. To wear a mask to keep viral particles from spreading is fairly hard to screw up. To wear a mask to stop viral particles from getting in is very easy to screw up. If someone is walking around with a water mist sprayer, is it easier to keep people dry by having them wear all manner of layers, or to simply drape a cloth over the mist nozzle?
- aredox 2y ago>People do not wear masks correctly to withstand being around sick people. This was abundantly clear during the pandemic. Enough people wear masks correctly, so well that almost all airborne diseases disappeared during COVID. But everyone seems to have forgotten that SARS-CoV-2 is extremely contagious, with a R0 extremely high amongst viruses (I think it is only topped by measles?), far higher than flu.
