How Contagion Spreads

Geographical distance no longer matters. Airports matter.

article-2523302-1A16634200000578-203_634x385In our connected world, distance is a relative concept. It takes less time to cover the 800 miles between New York and Chicago by air than it does to reach Albany, 150 miles north, by land. And that is as true for the flu as it is for you…

Effective distance focuses on airports to redefine what it means to be close. Airports are effectively near to one another if the flow of traffic between them is dense…For example, plenty of people travel from New York’s John F. Kennedy International Airport to London, he says, but fewer people fly from JFK to Albany. Effectively, London is closer to New York City than a small city in the same state. The same is true for Chicago. A small fraction of traffic is equivalent to a large distance between locations, and vice versa. (Popular Mechanics)

    This will be how the zombie virus spreads

    • Dewaine says:

      Depends on how quickly it activates in people. If it is slow, then it will get around the world fast. If it is fast, then it will tidal wave in one particular part of the world like lightening (think World War Z).

    This is true. Does this mean we should enhance the screening process for travelers potentially carrying contagions at airports?

  3. Gabriel says:

    I don’t think I can take any more increases in airport security.

  4. Dewaine says:

    We are all this together now, there really is no hiding.

    I’m not usually prone to violence. But there was one exception that time I boarded a flight and discovered the person seated next to me had a bad cold/flu or some other contagion. The perpetrator perpetually coughed out enough pathogens to infect the masses! The TSA’s ban on boarding a plane with sharp metal objects or heavy blunt weapons likely saved this poor soul from being beaten or stabbed within an inch of his life!
