| Abstract: | An SIVS epidemic model with vertical transmmission where the disease can recrudesce in the chromic phase is established and studied. The explicit formual of the threshold R0 and the stability conditions of the disease-free equilibria and the epidemic equilibria are given. |

| Keywords: | vertical transmission acutr and chronic phases recrudescence epidemic model equilibria |
