Schistosomiasis, also known as snail fever, is a parasitic disease caused by trematode worms of the genus Schistosoma. It is transmitted through contact with freshwater that has been contaminated with the larvae of these worms, which can penetrate the skin of humans who are bathing, washing, or swimming in the water. Schistosomiasis can affect the urinary tract or the intestines, and symptoms may include abdominal pain, diarrhea, blood in the stool or urine, and fever. It can also lead to complications such as anemia, liver damage, and bladder cancer. Schistosomiasis is prevalent in tropical and subtropical regions, particularly in Africa, Asia, and South America. It can be treated with medications such as praziquantel, but it is best to prevent infection by avoiding contact with contaminated water.
