Influence of cross-diffusion on the fecally-orally epidemic model with spatial heterogeneity
Influence of cross-diffusion on the fecally-orally epidemic model with spatial heterogeneity
A strongly coupled cooperative parabolic system, which describes fecally-orally epidemic model with cross-diffusion in a heterogeneous environment, was formulated and analyzed. The basic reproduction number $R_{0} ^{D}$ , which serves as a threshold parameter that predicts whether the coexistence will exist or not, is introduced by the next infection operator …
