Optimal survey designs for targeting chemotherapy against soil-transmitted helminths: Effect of spatial heterogeneity and cost-efficiency of sampling

Sturrock, Hugh J W; Gething, Peter; Clements, Archie; Brooker, Simon

Description

Implementation of helminth control programs requires information on the distribution and prevalence of infection to target mass treatment to areas of greatest need. In the absence of data, the question of how many schools/communities should be surveyed depends on the spatial heterogeneity of infection and the cost efficiency of surveys. We used geostatistical techniques to quantify the spatial heterogeneity of soil-transmitted helminths in multiple settings in eastern Africa, and using the...[Show more]
