“The idea is to not get infected in the first place” is not good thinking.
Given the long asymptomatic infectious period, both the “protect myself” and “protect others” effectiveness matter in a proposal for universal public wearing, although of course compliance is more incentivized by “protect myself”.
That said, I don’t question that these are good overall.
Well, if your chances of getting infected are drastically reduced, then so is the use of the “protect others” effect of wearing the mask, so overall these masks are likely to be very useful.
That said, a slightly modified design that filters air both on the in- and the out- breath might be a good idea. This way, you keep your in-breath filters dry and have some “protect others” effect.
Everybody wearing a respirator could be one of the equilibrium point of the social evolution under the COVID-19, though may be not the only one. Unfortunately, I did not figure other equilibrium point yet. To my best knowledge, nobody gives other end point of the social evolution in a rigors way.
Agree. My comments can certainly be seen as suggesting a starting approach and then refining that approach. However, I would actually expect to see a lot of zigs and zags, and possible multiple types of solutions that will work in different settings.
About the only thing I would say I have any high confidence about is that we need to start doing something. Masks, just like telecommuting for some, is one starting point. It might just end up being the crutch used to get over some hurdle. So I see things more as a stage where we will likely do some things that could be called trial and error approaches (but the error needs to be more on the “we cannot do this because I cannot stand doing X” side and not “we cannot do it this way because we just tripled R0!” side)
For sure people having a hard time breathing already will skimp on optional exit valve filtering, but you can sell it as helping-others to comply, and people will at least brag about how they’re doing it.
