Here we present a WAIT-style model of cholera (caused by the gram negative bacterium Vibrio cholerae), which has been the object of prior modeling efforts [12] , [29] - [31] , [33] . This specific iteration is based on a simulation of a 2010 outbreak in Haiti [32] . It is set with a population of 400,000 (the approximate population of the Carrefour section of Port Au Prince, Haiti), features seven ordinary differential equations, seven compartmentalized agents, and twenty parameters. It contains high-infectious and low-infectious water reservoirs, which are the mode of transmission [36] . Recent studies have examined other modes of transmission in cholera, (including transmission within households) [37] , but we have chosen to focus on waterborne transmission. Treatment and prevention is undertaken via vaccination, antibiotic administration, and modification of the contaminated water dynamics.
