The symptoms of schistosomiasis include acute symptoms, chronic symptoms, advanced symptoms, and symptoms of ectopic schistosomiasis. Acute schistosomiasis will present with fever, abdominal pain, diarrhea, generalized rash, hepatomegaly, and pressure pain. Chronic schistosomiasis will present with malaise, loss of appetite, chronic diarrhea, and pus and blood mucus stools. Advanced schistosomiasis will present with progressive worsening of ascites, hepatosplenomegaly, and upper gastrointestinal bleeding. When there is a history of ectopic schistosomiasis, the worms will be parasitized outside the portal system. Parasitization in the lungs will lead to pulmonary schistosomiasis, manifesting as cough and sputum, and parasitization in the brain will lead to cerebral schistosomiasis, manifesting as epilepsy and impaired consciousness.
