ABSTRACT In this review, I describe the progress in a study that focused on the risk factors for schistosomiasis around the globe for the purposes of the review. Human schistosomiasis affects 229 million people; at least 90% are in sub-Saharan Africa, and 54% are school-aged children. Schistosoma haematobium infects 112 million people, Schistosoma japonicum infects 3.1 million people, and Schistosoma mansoni infects 54 million people. Schistosomiasis can occur in endemic and non-endemic areas. A high risk of schistosomiasis can occur in, for example, preschool-aged children, school-aged children, and workers in endemic schistosomiasis areas. These people make contact with infested freshwater day by day. In addition, environmental factors and socioeconomic factors can affect the transmission of schistosomiasis. Various factors can cause the transmission of schistosomiasis, for example, climate changes and proximity to infested freshwater bodies. People with high risks for schistosomiasis need great attention for treatment and/or prevention programs. Risk factors for schistosomiasis, for example, human behavior and socioeconomic status, can affect the transmission of schistosomiasis. Many developing countries in Africa, Asia, and South America are at risk of this disease. High-risk people need special attention in programs for schistosomiasis elimination.
