News flash!
There are 309 MILLION people in America and 141 people have it. That is 0.00004563106796116505% of the population! How is that a mass hysteria?!?!?! More people contract MANY other diseases every minute.
This reminds me of an episode of House where he was on a plane and invoked mass hysteria and everyone on the plane got it, however, it was just a pure fake.
