What is Schistosomiasis? Schistosomiasis, also known as bilharziasis or snail fever, is a waterborne parasitic infection that damages internal organs. The most common symptoms are blood in urine and/or feces and an enlarged liver, diarrhea, abdominal pain, weakness, and anemia.
The symptoms of schistosomiasis are caused by the bodyâs immune system reacting to the schistosome eggs. The eggs can lodge in a number of areas around the body causing inflammation (swelling). This can then lead to the formation of tissue masses called granulomas and stiffening of the tissue called fibrosis.
