Spatial-temporal dynamics of rabies in ecological communities
Spatial-temporal dynamics of rabies in ecological communities
As new species invade novel geographic regions, they have the propensity to reorganize multi-species community interactions. The expansion of the rabies virus in Europe and across the eastern United States provides a model system for comparing the linkage between community dynamics and the spatio-temporal dynamics of an invading parasite and its hosts. The European rabies epizootic has been largely restricted to a single terrestrial carnivore host — the red fox — while the US rabies epizootic has involved multiple terrestrial carnivore hosts including raccoons, foxes, skunks, coyotes, and domestic animals. This chapter reviews mathematical models that predict the spatio-temporal patterns of rabies occurring in different reservoir hosts, and explores the implications of the geographic range expansion of the rabies virus within a specific host — the raccoon — on host-shift and spill-over dynamics among alternate hosts.
