Abstract
In this paper, we investigate an SVEIR epidemic model with reaction–diffusion and nonlinear incidence. We establish the well-posedness of the solutions and the basic reproduction number mathfrak{R}_{0}. Moreover, we show that the disease-free steady state is globally asymptotically stable when mathfrak{R}_{0}<1, whereas the disease will be persistent when mathfrak{R}_{0}>1. Furthermore, using the method of Lyapunov functional, we prove the global stability of the positive steady state for the spatial homogeneous model.
