Schistosomiasis, also known as snail fever and bilharzia,[9] is a disease caused by parasitic flatworms called schistosomes.[5] The urinary tract or the intestines may be infected.[5]

Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine.[5] Those who have been infected for a long time (chronic infection) may experience liver damage, kidney failure, infertility, or bladder cancer.[5] In children, it may cause poor growth and learning difficulty.[5]
