A common trope in zombie mediums in to base the virus off of rabies. While this choice does have some obvious reasoning to it, it has been long over done. Relatively recently, The Last of Us came out and broke away from this by basing their virus off of chordyceps, more commonly called the ant zombie fungus.
This worked really well, with every step of the infected design process, clickers to airborne spores, to be based off of the original fungus. What about a Cholera based zombie Infection? Similar to how a Chordyceps base introduced Clickers and Spores, what notable features would be brought along by a Cholera base?
