WBUR: ‘The Ebola Coaster’: Boston prepares intensively for what-ifs
WBUR - 09/24/2014
Earlier this month one research team put the risk of an imported Ebola case in North America at somewhere between 1 and 18 percent by the end of September, based on analysis of air traffic from West Africa to the rest of the world.
The risk has undoubtedly declined since then as commercial flights to and from Ebola-affected countries have been curtailed by an estimated 70 percent.
“That just delays the international spread,” says Alessandro Vespignani of Northeastern University, a co-author of the analysis. “It might not happen in September or October. But perhaps in November. We have to expect the importation of cases as the number of cases in West Africa grows quickly.”
