Fig 2. (a) The basic reproduction number R ₀ and (b) disease prevalence as a function of increasing movement rate (k) in a spatial network composed of 10 regions with varying levels of heterogeneity in transmission intensity.

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 R _0,i in 100 simulations for each level of spatial heterogeneity. Note how variance increases with CV, while the average remains similar among configurations.
