摘要：

In this paper, we investigate the existence and nonexistence of traveling wave solutions in a nonlocal dispersal epidemic model with spatiotemporal delay. It is shown that this model admits a nontrivial positive traveling wave solution when the basic reproduction number R-0 > 1 and the wave speed c >= c* (c* is the critical speed) and this model has no traveling wave solutions when R-0 <= 1 or c < c*. This indicates that c* is the minimal wave speed.
