Percent difference in cumulative incidence predicted by the transmission model for adults, children, and the whole community for increasing heterogeneity of travel by age group. Increasing heterogeneity was done using a proportionality constant where traveladult = ctravelchild and c takes values of 1 (low), 2 (medium), or 3 (high). Low-within village transmission corresponds to a baseline R0 of 0.79 and high within village transmission corresponds to a baseline R0 of 1.43 (R0 increases slightly with increasing heterogeneity)
