Sensitivity analysis: impact of cost assumptions on the relative cost of semiannual/annual mass drug administration (MDA).

The values in the table are the ratio of total program costs, for semiannual MDA/annual MDA. This ratio shows which approach is less expensive (with values Results are shown for Indian and West African settings, with varying pre-control mf prevalence levels. Coverage of MDA was assumed to be 70% per round (percentage of total population). The number of treatment rounds required for elimination differs between these settings (see table 4) and hence the total program costs. Given levels of mf prevalence are based on diagnosis with 60 µL blood smears.n.r.: not relevant, because costs of drugs, which are all donated, are not included in the cost projections.abaseline assumptions.
