Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, a new study of global airline travel patterns shows. The authors used a model that predicts that three people infected with Ebola are predicted to fly from West Africa (Guinea, Liberia, and Sierra Leone) to low-income and lower-middle-income countries every month if no exit screening takes place.
