Bottom Line: We aimed to map the probability of Schistosoma haematobium infection being >50%, a threshold for annual mass praziquantel distribution.Parasitologic surveys were conducted in Burkina Faso, Mali, and Niger, 2004-2006, and predictions were made by using Bayesian geostatistical models.Clusters with >50% probability of having >50% prevalence were delineated in each country.

ABSTRACT
We aimed to map the probability of Schistosoma haematobium infection being >50%, a threshold for annual mass praziquantel distribution. Parasitologic surveys were conducted in Burkina Faso, Mali, and Niger, 2004-2006, and predictions were made by using Bayesian geostatistical models. Clusters with >50% probability of having >50% prevalence were delineated in each country.

Figure 1: Prevalence of infection with Schistosoma hematobium at 418 survey locations in Burkina Faso, Mali, and Niger, 2004–2006.

Mentions: Parasitologic data were collected in coordinated school-based field surveys in Burkina Faso, Mali, and Niger (Figure 1) during 2004–2006 (preintervention) by using standardized protocols (available on request). The collated dataset covered a spatially contiguous area, ≈2,750 km × 850 km, and included the infection status of 27,939 school-age children in 418 randomly selected locations. Infection status was defined according to egg count determined by microscopic examination of urine samples; >1 S. hematobium eggs indicated infection.
