Table 2 Number of annual rounds in years to transmission elimination predicted by the deterministic model with fitted parameters to a medium transmission area for Ascaris (R0 = 2.34) given 0, 2 or 5 years of community MDA for LF at an effective coverage level of 70% across each age grouping. Albendazole drug efficacy is embedded in the calculations. Numbers in bold reflect predictions, based on the deterministic model, of crossing the transmission threshold within four years
