We propose a mathematical model for the transmission dynamics of cholera under the impact of available medical resources. Written by Alisha Kramer Vibrio cholerae is the causative agent responsible for cholera. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water.

The model describes the interaction between the human hosts and the pathogenic bacteria and incorporates both the environment-to-human and human-to-human transmission routes. This doctrine is that cholera propagates itself by a morbid matter which passing from one patient in his evacuations is accidentally swallowed by other persons as a pollution of food or water. The model describes the interaction between the human hosts and the pathogenic bacteria and incorporates both the environment-to-human and human-to-human transmission routes.
