A few schools have already been closed in France.
It is going to have a significant impact overall. For how long, I have no clue. I mostly work from "home" these days - but with some traveling. I have a lab at home. But no travel planned lately so far...
Speaking of masks, fun (if you can call it that) but absurd fact: there has been a hot topic very recently over here. Obviously masks are highly suggested as a means of protection, but at the same time, there's a law that forbids anyone to wear a mask in public areas (for dang security reasons as it hides your face). So no one really knows whether we can get out wearing one or not, but you're likely to get fined if you do, even though the ministry of health has told people to wear one at the slightest sign of cold/flu to protect others.
Even in China, AFAIK, they are allowed to wear masks even though mass surveillance is pervasive over there. So are we getting even more totalitarian than China is? Maybe.
