Abstract. In this paper we present the dynamical feature of dengue disease which is now endemic in more than 100 countries in the world. We develop a mathematical model taking into account the hospitalized compartment to present transmission of mosquitoes (Aedes aegypti) virus and its existence in human population. It is shown that the stability of the equilibria in the proposed model can be controlled by the basic reproduction number of the disease transmission. We use Lyapunove function theory to present global asymptotical stability. Finally, we show parameter estimation that characterize the natural history of this disease with numerical simulations.
