| Abstract: | An SIRS model for diseases with two competing pathogen strains is studied in this paper.Both total crossing immunity and density-dependent host mortality rate are assumed.We derive conditions of competitive exclusion between two pathogen strains,and those of the disease persistence. |

| Keywords: | SIRS epidemic model crossing immunity competitive exclusion |
