Elzaki Decomposition Method for Solving Epidemic Model

Abstract

This study investigate the application of Elzaki Decomposition Method in finding the approximate solution to the problem of the spread of a non-fatal disease in a population which is assumed to have constant size over the period of the epidemic. Epidemic models are nonlinear system of ordinary differential equation that has no analytic solution. The series solutions obtained by Elzaki Decomposition are compared with the existing results in the literatures; likewise, some plots were presented.The obtained results validate the efficiency of the method.
