Solution of the epidemic model by Adomian decomposition method

In this article 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 is considered. Mathematical modeling of the problem leads to a system of non-linear ordinary differential equations. Adomian decomposition method is employed to solve this system of nonlinear ordinary differential equations, the problem of convergence has been addressed. 2005 Elsevier Inc. All rights reserved.
