Abstract
This article deals with the non-linear mathematical model of disease, poverty and corruption in the human population. The connection between poverty and corruption as well as poverty and disease are discussed and explained. The whole model is divided into five sub-models. The equilibria, the basic reproduction number and stability of the model as well as the sub-models are found and analyzed analytically. Numerical simulations of the model is carried out to support the analytical results. Also, the sensitive parameters of the model are found and shown using two dimensional and three dimensional graphs.
Keywords: Basic reproduction number, poverty, corruption, disease, equilibria, stability, mathematical model
