Schistosomiasis in China



A Joint Research Interchange (JRI) has been initiated between CHAART and the School of Public Health at the University of California, Berkeley. The first year of the JRI focused on a GIS analysis of schistosomiasis in relation to the drainage network surrounding a village in southwestern Sichuan Province, China. The goal was to develop a hydrologic model that could be used to identify risk factors for disease transmission. The GIS database included topography, irrigation networks and natural drainage systems, demographics, location of residences and work areas, snail habitats and night-soil storage sites, snail population densities, and disease incidence. It was determined that risk was largely dependent on age and housing location. In the second year, the JRI will focus on using remote sensing data to extend the village model to the Anling River watershed.
