由两种彼此完全交叉免疫的病毒导致的流行病模型
A Two-strain Epidemic Model with Total Cross Immunity
摘要
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.关键词
