If they had ebola, we would certainly know about it shortly after the planes wheels stopped.
It’s not like aids in that respect. It overwhelms the immune system very quickly, once it gets rolling..
I think that if it can’t kill more than a couple thousand people in Africa with the populations and culture there, over a time period of decades, then it certainly can’t do much in the US, even if it did get out.
As I see it, frankly speaking, the stuff is nasty but it’s less dangerous to our population then the common flu.
