The Dynamics of the Pulse Birth in an SIR Epidemic Model with Standard Incidence
Abstract
An SIR epidemic model with pulse birth and standard incidence is presented. The dynamics of the epidemic model is analyzed. The basic reproductive number R∗ is defined. It is proved that the infection-free periodic solution is global asymptotically stable if R∗1. Our theoretical results are confirmed by numerical simulations.
