Also one thing not factored in to NYC is the number of people that have already gotten the hell out of Dodge. I personally know of at least one douchebag that fled all the way to his parents ranch in Wisconsin or Wyoming and several others that went to the four corners of the nation.

Not saying he was already infected or anything, but some of those people were so when they do get sick, they won't show up in NYC stats...they will however create lots of other clusterfuckery in other locations.
