Never happen? It may happen sooner than we think. I have BIG issues with this. It's bad enough we have labs all over the world screwing up and losing vials of dangerous bugs, but the CDC is the LAST agency I'd trust to keep things safe. And to take these two individuals to the 39th largest city in the US to treat something that there is no guarantee of curing in the hopes they caught them early enough to nurse them through? No. No. No. No. Are they going to quarantine the aircrew, too? How about the ground crew at the airport? Guess where ground zero is going to be when this shit hits the fan?
