Abstract

Abstract

The dynamics of periodic reactiondiffusion epidemic models with delay and logistic growth was investigated based on the theory of dynamic systems. Firstly, the existence of the global attractor of the ω operator associated with the periodic semiflow was proved. Next, the basic reproduction number of the model was introduced via the next generation operator. Finally, by means of the persistence theory and the comparison principle, the sufficient conditions for the disease persistence and extinction were obtained. If the basic reproduction number is less than 1, the diseasefree periodic solution will be globally asymptotically stable and the disease will go extinct. If the basic reproduction number is greater than 1, the system will be uniformly persistent and the disease will become endemic.
