Fig. 5From: Refined stratified-worm-burden models that incorporate specific biological features of human and snail hosts provide better estimates of Schistosoma diagnosis, transmission, and controlEstimated ensemble mean biological parameters for twelve Msambweni villages, plotted against observed egg-count prevalence data. The left column (a) has maximal egg release (ρ 0), crowding (w 0), and aggregation (r) mean parameter values for children (0 to 20 years old) graphed together for every village; the right column (b) has values for adults. Dashed lines are linear regressions for the twelve village values for each parameterBack to article page
