State quarantine requirments

Funny how the states that were against building a wall are now imposing self quarantines to people coming into their own state. Some were even banning refugees from another state but that has since been rescinded.

And a lot of countries are keeping people completely away from entering their borders though. 

Don't get me wrong. I don't think every country should erect walls but it's funny in times like this people begin to see the point.

I just wonder how international travel is going to change after all this. I'm thinking it will dramatically.
