Actually, you should take a breakout of zombism, an epademic, if you will, very seriously. I have actual, real life proof. The Centers for Disease Control (in USA) published and distributed a manual on how to survive a Zombie Apolocypse. I'm not making this up. Do your own search of the CDC and you will find it.
CDC did publish this manual as a gimmik to communicate proper preparation for any diaster which might disrupt services and, perhaps, briefly, disrupt civil order.
