Gotcha. So by crippling the economy in Guinea, Liberia and Sierra Leone and making it extremely difficult to fly in food, medical supplies and health workers, you think we'll contain the outbreak. I'm not a public heath expert, but public health experts I've heard from all indicate that that's actually the way to guarantee that the epidemic spreads.
I don't believe their economies are very dependent on air travel. They certainly were not dependent on Mr. Duncan's trip to Dallas. Note that I said "nonessential". I have no problem with aid of various sorts flying into those places.
