Abstract:
This paper presents the analysis of SEIR epidemic model with time delay. We assumed that the susceptible individuals obey the logistic equation with saturated nonlinear incidence term with susceptible. The disease free equilibrium is stable locally asymptotically when R_0<1 and unstable equilibrium exists, when R_0>1. ForR_0>1, the endemic equilibrium is stable locally as well as globally. Finally, the numerical solutions for the theoretical results are presented.
