Ebola outbreak in the U.S.? Probably not happening.
The Washington Post - 09/19/2014
So far, other than a few patients evacuated by air ambulance from West Africa, there have been no known cases of Ebola-infected people traveling from that region to other parts of the world. But could that luck be running out?
Every month, week and day that the Ebola epidemic continues to rage, the chances of exportation to other countries increases. But at the moment, the likelihood of an Ebola victim landing, unchecked, in the United States is fairly small, according to researchers who have run computer simulations of air travel between affected countries and other parts of the world.
If the deadliest outbreak in history continues at its current pace, the probability of an exportation of Ebola to the United States by the end of September is between 3 and 15 percent, according to Alessandro Vespignani, a Northeastern University professor whose team has been continuously updating its model.
