@greg_travis @hjelle_brian Prevalence was probably 100x higher some places at peak vs. now. The usual masks people wear aren't 99% effective, so this is probably not correct. But the point of risk compensation and the risk also not being 100x lower is valid.
@greg_travis@hjelle_brian的患病率可能比现在高出100倍。人们通常戴的口罩没有99%的效果，所以这可能是不正确的。但风险补偿点和风险不低于100倍的点是有效的。
