A Conventional Series Solution of Epidemic Models (Type-I & II)

Abstract

The purpose of this paper is to determine series solutions for two standard basic epidemic models i.e Type-I (Vaccination SIR Model) & Type-2 (SIR model).The model equations are formed by nonlinear differential equation with first order. The basic series solutions of Vaccination SIR Model & Basic SIR model are derived by using Homotopy perturbation method.
