摘要
An SIRS epidemic model with pulse vaccination and non-monotonic incidence rate is introduced. Some sufficient conditions for the global attractivity of the infection-free periodic solution and permanence of this system are presented. Two numerical simulations are also given to illustrate our main results. (c) 2012 Elsevier Ltd. All rights reserved.
