It is a bit surprising to me that there is such a strong focus in the US on school closures and mask wearing (here on HN but also in the major newspapers). It is my impression that in quite a few European countries there have been, and to some extent still are, significant debates about the effectiveness of both these measures. On the other hand, there appears to have been a much more universal implementation of othe…
"Stay home" is one of those things that are on every list of recommendations, but it's completely non-viable in practice because of the way US handles healthcare in work context. Keep in mind that there is no federal requirement for paid sick leave, and only 13 states mandate it. Consequently, 30% of workers don't get any paid sick leave at all - mostly the lowest-paying jobs, that are paid the least (and so taking an unpaid day off can easily mean an unpaid bill etc), and who interact with random people the most.
And don't forget that employment in US is "at-will", meaning that businesses can fire workers without giving a reason. FMLA limits that somewhat wrt unpaid sick leave, but 1) it only applies to businesses with at least 50 employees, and 2) it only applies to illnesses that are incapacitating to the person claiming sick leave.
The focus is on mask wearing right now, because the return to stay-at-home is clearly not happening, and so people go and mingle. If they mingle with masks, they definitely reduce the transmission rate enough to notice - there's ample evidence of that. What's unclear is just how large the effect is.
Also, why focus on Europe alone? We could also look at Japan, which seems to have made a bet largely on mask wearing - and has some impressive results to show for that.
