As far as I have seen, currently people don't use masks for close contact talking situations (family, friends, work, chatting...).

With mask usage in Germany I see only negative trends in the growthrate of both case and death. I think to make them work something has to be changed.

There is a good chance that it now only works as a reverse placebo - it makes people feel confident and pushes them into more risky behaviour - most likely net negative.

Jena's claiming that they made a difference for them. We'll see what happens in Berlin and Munich after the protests...
