I disagree. When your house is on fire, you don’t keep adding wood.
If a town has 50 cases from local spread, do you want to add another 50 from Italy? Or Seattle?
Personally, I am not of the ”let it burn to the ground” mentality.
Just to be clear—I am in favor of stopping all travel in and out of the US.
But, we should not kid ourselves—it is too late now.
The main reason to stop all travel is that we are spreading it around the world—and so the travel stop would have to be reciprocal—a win win.
