How about just closing the borders.
It would be impossible, even if this thing were to spread viciously, to get those who rule the world to do that. Everything's about the economy. That and gaining advantage in wars.
What's going to happen when (not if) this thing gets into refugee camps and/or war torn areas? I doubt we the little folk would even know the severity of any outbreak.
In the US, I wonder what's going to happen when schools begin opening. The hordes crossing in from the south and who knows how many refugees from everywhere are going to be enrolled.
