In this paper, we will obtain analytical approximate solutions of the HIV infection model of CD4+ T-cells. This model corresponds to a class of nonlinear ordinary differential equation systems. To this end, we combine the Natural transform with the Adomian decomposition method for solving this model. The numerical results obtained by the suggested method are compared with the results obtained by other previous methods. These results indicate that this method agrees with other previous methods.
