Why hasn’t the U.S. closed its airports to travelers from Ebola-ravaged countries?

Researchers who have modeled the risk of the international spread of the Ebola virus have been clear that the longer the outbreak goes on and the bigger it is, the more likely Ebola is to spread beyond West Africa to the rest of the world.
“If the epidemic continues at this growth rate and produces more and more cases, obviously the probably increases with time,” said Alessandro Vespignani, a Northeastern University professor whose team has been updating its model of the chance of global exportation of Ebola cases. “That means that in October, it would be 20 percent or more, and then it will grow. The probability is increasing.”
