Taiwan, Japan, Singapore, Hong Kong ... they all wear masks to some extent, normally in non-pandemic periods. They now do it at scale. They're at the bottom of the barrel in cases today (Russia is too and I don't really understand why unless they're lying). So, perhaps we should just start wearing masks. It costs nothing, assuming it's possible to get them, though for whatever reason our smartest people - both in the actual elite and here on HN - exclaimed that wearing a mask "does nothing". And one of the results of everyone telling us back in January and February that "masks do nothing" is that we're now 2 months behind procuring a cheap item that could actually do a lot of good. What a damn shame.
