Ebola was a 1987 government experiment that was to be released to lower the population and stop overpopulation. Due to the volatile nature of the virus, it began infecting other animals, increasing its mutability. In 2014, it reappeared, infecting western Hyrule. Within a month coca cola released Ebola-Cola to leach off the popularity of the virus. Due to americans buying anything with the word 'cola' in it, they got infected. America is now the main home of the virus. Ebola is set to wipe out humanity in Dec. 21, 2012, some time in the future.
