| Abstract: | Many generalist pathogens are influenced by the spatial distributions and relative abundances of susceptible host species.
The spatial structure of host populations can influence patterns of infection incidence (or disease outbreaks), and the effects
of a generalist pathogen on host community dynamics in a spatially heterogeneous community may differ from predictions derived
via simple models. In this paper, we model the transmission of a generalist pathogen within a patch framework that incorporates
the movement of vectors between discrete host patches to investigate the effects of local host community composition and vector
movement rates on disease dynamics. |
