(a) The basic reproduction number <i>R</i>₀ and (b) disease prevalence as a function of increasing movement rate (<i>k</i>) in a spatial network composed of 10 regions with varying levels of heterogeneity in transmission intensity.

<p>Lines represent means and shaded areas 95% confidence intervals. Spatial heterogeneity in transmission intensity increases with the coefficient of variation (CV). (c) Box-plots shows the distribution of patch-specific transmission intensities <i>R</i>_0,<i>i</i> in 100 simulations for each level of spatial heterogeneity. Note how variance increases with CV, while the average remains similar among configurations.
