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).
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.
