Airports ranked for spreading disease

Many of us fly to WDW or DLR, so this is an interesting article from MIT that talks about a study that ranked US airports for their potential to spread disease. 

...a new study by researchers in MIT's Department of Civil and Environmental Engineering (CEE) shifts the focus to the first few days of an epidemic, determining how likely the 40 largest U.S. airports are to influence the spread of a contagious disease originating in their home cities.

The top 2 are LAX and JFK, with O'Hare also in the top 10.  Airports such as MCO (Orlando), SNA (John Wayne)  and MDW (Midway) are not on the top 10 list.  You might think Orlando would rank high based on the number of world travelers that use it, but the MIT model looked at many other factors.
