If an infectious disease breaks out in your country do you a) close the gates, b) let people travel, c) do nothing?

We picked d) ban travel from one of many countries with active infections to score political points.

We didn’t even do that properly - American citizens were allowed to return, weren’t screened, and were asked to observe a “voluntary” quarantine.

We wound up mostly getting it from Europe, where we similarly didn’t restrict until it was far too late.

I agree -- shut the border completely or not at all; but I was referring more about where it started rather than where it spread to.
