State Department warns Americans: Don’t travel abroad, come home if overseas

The announcement is the government’s most severe warning about international travel.

I have never seen this ever. The USA is virtually locked down. I know Coronavirus is serious, but does it grant this much? What does Governemnt know what we do not know?

PS: My friends (American) in Japan told me that they feel safer living in Japan. Japan has less Coronavirus Infection and Better health Care.
