Edit: I decided to clarify why I think it is a large-scale change. I cannot think of any other action we are actively obliged to do by law, except for possibly covering gentials, when leaving our own house/property. Introducing any such obligitory action is, in my opinion, a large-scale change in mandated behaviour.
i am probably missing something obvious but no, there are plenty of places that are not america or Europe.
It was a light-hearted comment about a country that was part of Europe and now isn't.
Maybe in some European countries. The Dutch public health authorities are very skeptical about the usefulness of masks and continue to resist a mask requirement except in places where distancing is impossible (like public transport).
