Abstract: A delayed HIV-1 with Holling II type infection model was investigated. Using the uniform persistence theory and successive iteration method, the conditions on the permanency of the model and the global asymptotic stability of the endemic equilibrium were obtained, which improve the results in the relevant literatures.
