I think everybody who travels from those countries should be examined and quarantined here or upon their arrival at the European airport where they transfer to the US bound plane. Personally, I think stopping air traffic from those places would be the cheapest and easiest. But otherwise, go back to the Ellis Island model and quarantine the arrivals.
That said, some lab is working on developing a quick and accurate test for Ebola and hopefully then everyone who has traveled there will be required to take it upon their arrival in Europe or the US.
I'm just dumbfounded that at the very least we did not do this. And now it's here and people are still arriving daily from Ebola hotspots.
It's turning into a "closing the barn door after the horse ran away" scenario. By the time someone in Washington gets serious about restricting and/or screening travelers, we could have already let thousands of infected people into our country.
