摘要
In this paper, a periodic epidemic model with age structure in a patchy environment is introduced. We investigate its global dynamics in term of the basic reproduction number R-0, and show that there exists at least one positive periodic state and the disease persists when R-0 > 1 while the disease will die out if R-0 < 1. Some numerical examples are given to confirm our analytic results and to show that the age and spatial heterogeneities are important factors for the global dynamics.
