Globally, schistosomiasis is a major source of morbidity and mortality. The unique schistosomal life cycle limits endemic areas to tropical and subtropical zones, but these areas exist around the world and may even increase with some agricultural practices. Although freshwater lakes and streams are usually identified as the source of the disease, man-made reservoirs and irrigation systems are increasingly implicated in some countries. Indeed, geographic spread continues because of water resource engineering issues in developing countries and the migration of infected populations.
