Here, we build on the strain theory of host-pathogen systems proposed by \citet{Gupta_1998}, considering a scenario where a collection of populations undergoing local dynamics are furthermore interconnected through the movement of individuals between populations. We simulate disease dynamics on this system, characterizing the effects of parametrization and network structure on these dynamics. This work is divided into three sections: first, we explore a case of interconnected populations which have been parametrized to display identical dynamics in the absence of host migration. Second, we consider cases where parameters differ between populations. Finally, we explore the role of network structure on disease dynamics in larger networks of connected populations.
