Table 1 STH prevalence values (any infection) in infected source villages used in simulations. The prevalence values are achieved by setting the basic reproductive number R₀ and k (the shape parameter of the negative binomial distribution that describes the aggregation of parasites among hosts). The parameters required to achieve a desired prevalence value vary by species, because other parameters, for example, the worm life expectancy and transmission age structure, also differ by species
