It starts with a simple itch, nothing more. Maybe a few random spasms or the occasional shudder but you'll think nothing of it. Then you'll get blood shot eyes... Not enough sleep? It gets worse, much worse. The itching turns to scratching, clawing at you skin until it bleeds... and bleeds and bleeds. Then comes the anger which tips you over the top making you brake into a full blown seizure. Madness. You still with me? Well you won't be if they catch you, you'll be one of them...infected.
