| Abstract: | It is discussed a SIR epidemic model with Logistic growth and infection age. The disease-free equilibrium E0 is globally asymptotically stable if R0<1, and also the endemic equilibrium E is locally asymptotically stable if R0>1, by using the theory of differential and integral equation. |
| Keywords: | mathematical models Logistic growth reproductive number equilibrium stability |
