Question

Quizplus · Accepted Answer

Schistosomiasis is a waterborne parasitic disease caused by the Schistosoma parasite. It is typically contracted when people come into contact with contaminated freshwater sources, such as rivers and lakes, that contain the parasites released by snails. The construction of dams can increase the risks of contracting schistosomiasis by creating new freshwater habitats and increasing the population of snails that serve as a host for the parasite. Additionally, these habitats may attract more people who rely on freshwater sources for swimming, bathing, and fishing, putting them at greater risk of exposure to the parasites.
