Table 4 Time to 2 % target prevalence based on egg-test diagnostics. Shown values represent ensemble mean ± SD of program duration (in years) required to reach a target Schistosoma haematobium infection prevalence ≤ 2 % (T(f C , τ)), for different choices of coverage (f c , columns) and inter-treatment periods (τ, rows). Upper panel A shows results for a high risk Kenyan village treated by CWT; Lower panel B – a low risk Kenyan village treated by SBT. Full results for different delivery strategies in high- and low-risk areas are shown in Additional file 5
