Abstract: This paper is concerned with the traveling waves of a nonlocal dispersal SIR epidemic model with delay and nonlinear incidence. The threshold dynamics are determined by the basic reproduction number R0 and the minimal wave speed c*. First, when c > c*, R0 > 1, the existence of the traveling waves is proved by applying Schauder's fixed point theorem and a limiting argument. Then, when 0 < c < c*, R0 > 1 or R0 ≤ 1, the non-existence of traveling wave solutions is established by two-side Laplace transform.

Key words: Non-local dispersal, Traveling wave solution, SIR model, Schauder's fixed point theorem
