Estimating true prevalence of < i > Schistosoma mansoni < /i > from population summary measures based on the Kato-Katz diagnostic technique

Conclusions/SignificanceEstimation of ‘true’S. mansoni prevalence is improved when taking into account geometric or arithmetic mean infection intensity in a population. We supply parametric functions and corresponding estimates of their parameters to calculate the ‘true’ prevalence for sampling schemes up to 3 days with triplicate Kato-Katz thick smears per day that allow estimation of the ‘true’ prevalence.
