Abstract. Some continuous time, discrete space, metapopulation mod-
els that have been formulated for disease spread are presented. Motiva-
tion for such a formulation with travel between discrete patches is pre-
sented. A system of 4p ordinary dierential equations describes disease
spread in an environment divided into p patches. The basic reproduc-
tion number R0 is calculated, with the disease dying out in each patch
if R0 < 1. If travel is assumed to be independent of disease status, then
numerical results are cited that indicate that for R0 > 1 solutions tend
to an endemic equilibrium with the disease present in each patch. The
system is extended to include cross infection between several species. A
second extension involves keeping track of both the current patch and
