摘要：In this paper, we are concerned with an SIR epidemic model with infection age and spatial diffusion in the ca of Neumann boundary condition. The original model is constructed as a nonlinear age structured system of reaction–diffusion equations. By using the method of characteristics, we reformulate the model into a system of a reaction–diffusion equation and a Volterra integral equation. For the reformulated system, we define the basic reproduction number R0 by the spectral radius of the next generation operator, and show that if R0 1, then the dia in the system is persistent. Moreover,
