A little Ebola panic might be helpful

The official argument, counterintuitive but seemingly true, is that we can’t kick Ebola if we don’t keep travel open. Meaning, if we don’t send troops and health workers to nip the disease at its source, we have no chance of stopping it. (Question du jour: How many cases before a place becomes a source?)

A physicist at Northeastern University in Boston, Alessandro Vespignani, has developed a computer model to predict the spread of Ebola via air travel. His model indicates that halting travel won’t stop the spread of Ebola. But by applying a common-sense model from one’s own noggin, might we prevent more cases from arriving to our shores?

If we dare, it makes exceptionally good sense to treat travelers from infected countries with exceptional scrutiny on this end of the trip.
