Differential Transform Method (DTM) was employed to attempt the series solution of the model. The validity of the DTM in solving the model was established by classical fourth-order Runge-Kutta method implemented in Maple 18. The comparism between DTM solution and Runge- Kutta(RK4) were performed. The results obtained confirm the accuracy and potential of the DTM to cope with the analysis of modern epidemics.enSIR Infectious Disease Model, Differential Transform MethodArticle
