Researchers at MIT used network theory to put together a model of how an infectious disease might spread around the world with the help of American airports. The model shows which features—geography, connectivity, levels of use—most impact the spread of disease and use that to predict which airports would be at the heart of an outbreak.
Some are not a shock. (“Oh, you say JFK and LAX could serve as worldwide hubs for disease?”) But the model also reveals some surprising spark points. Like, say, Anchorage. It’s also interesting to see the order that the model ranks airports in. Would you believe that Honolulu has more disease-spreading power than Atlanta?
