Modelling the spread of diseases in animal populations

Modelling the spread of diseases in animal populations

The population dynamics of pathogens with multiple hosts. Andrew Dobson1 . Most mathematical models examine the dynamics of a single pathogen in a single host species. Many emergent disease problems arise when a pathogen utilizes more than one host species. I will present a framework for examining both the initial and transient dynamics of pathogens that infect more than one host species. The models I will describe build upon the initial work of Dobson and DeLeo (1996)[1]; and rescale the parameters of the model using underlying allometric relationships and life history invariants reduces the initial complexity of this task. Results based on these analyses will be compared with data collected from a variety of host-parasite systems in North America, Hawaii and Serengeti, Tanzania.
