| Abstract: | This paper considers an SIS epidemic model with nonlinear incidence rate and chronic stage where the disease can recrudesce.The explicit formula of the threshold and stability conditions of the disease-free equilibria and the epidemic equilibria are given. |

| Keywords: | Nonlinear incidence rate Acute and chronic phases Recrudesce Epidemic model Equilibria Global stability |
