Traveling waves in a delayed SIR epidemic model with nonlinear incidence

作者:

Highlights:

• We study the traveling waves of a diffusive SIR epidemic model with a general nonlinear incidence.

• We obtain the threshold dynamics for spatial spread of the disease.

• We show that c* is the minimum wave speed for the existence of traveling wave solutions.
