Table 2 Simulation scenarios. All scenarios were run assuming low (< 20%), medium (2530%) and high (6070%) STH prevalences in the source village. All scenarios were run for A. lumbricoides and hookworm. MDA scenarios were run with once- and twice-yearly community-wide treatment (75% coverage of all age groups except infants, random compliance) and with treatment of pre-SAC and SAC only (75% coverage, random compliance, treatment frequency according to WHO guidelines)
