Take a peek at the trajectory of COVID-19 cases in South Korea.  Hint: It’s parabolic.

Then, go to

https://flightaware.com/live/  pull the map over to Incheon Airport (S. Korea) then hover cursor over any, of the many flights now heading to the US to see where it’s going.

Then ask the question: Might any of those flights from Incheon to America contain infected individuals?

Am I wrong in thinking that this is insane?

They did not stop flights coming from China!!!

Economy is #1 I guess!

Yes.  But, their #1 priority will crumble into dust without public health.

TPTB have no choice. Do they understand that?
