It’s too late.

OP made clear we are now past the point of no return. Stopping all travel to/from China now is merely going to delay the inevitable by a few days or weeks. The infection is already here.

It is no longer a matter of “if”, but “when”.

Imagine if you knew a 30-60 day hurricane is absolutely definitely going to hit your area in 2 to 4 more weeks. You KNOW there is going to be damage and destruction, looting and panic, but you can prepare for it and likely survive the hurricane, the looting, and the panic-buying. If you aren’t prepared, your may still survive, but your odds are greatly diminished.

The good news is that those with healthy bodies and a robust immune system (and adequately stocked with supplies) may get infected but experience little or no symptoms, or may experience something similar to a bad flu. Infection does NOT mean Death.

But the point is, it’s too late to call Washington.

The infection is already here.
