Schistosomiasis is transmitted via contact with water that contains a specific freshwater snail ( Oncomelania hupensis quadrasi), which along with the human host acts as a carrier for the parasite. Schistosomiasis incidence is attributed entirely to water pollution, poor sanitation and hygiene because its lifecycle is not only dependent upon the snail and human hosts, but also requires human excreta in the water body and, therefore, is highly dependent on poor household sanitation, and, in many cases, defecation of farm workers and fisherfolk in water bodies and agricultural fields. The disease is commonly found in areas with irrigated agriculture in Eastern Mindanao and the Visayas, where the snail is found.
