...the dead will walk the earth...

       The Outbreak happened two years ago. Starting in an American lab where scientists were working on a cure for Meningitis after a small out-break took place in Miami. The cause was found to originate from the African Giant Snail, which carried rat lung worm, which causes Meningitis and death. As the snail was very similar to its smaller cousin, the Cuban snail, many children became sick before the cause was discovered and preventative measures were taken. The idea was for a cure similar to that of the rabies vaccine (as both are encephalitic diseases) would be made. In the beginning, it worked. It didn't CURE anything. But it did help prevent any more cases.
   As with all vaccines, however, this one was injecting people with a highly contagious disease which attacked the central nervous system, in hopes that their immune system could do the rest. Then the disease mutated. Another vaccine was created. Then it mutated again, and again.
   Much like Rabies, a bite was all it took.
     The Outbreak was almost over-night as those infected in South Florida migrated upwards to escape, bringing their slowly mutating loved ones with them. Being a major port, the epidemic swept the country first, then the world.
