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.
Nearly 10,000 medical teams are giving out water purification tablets and treating people who have had contact with polluted flood water and so are at risk for getting snail fever, or schistosomiasis. Snail fever, or schistosomiasis, is a parasitic disease of the liver, gastrointestinal tract and bladder. The disease is caused by a specific worm which enters a person's body from infested polluted water. There are three main species of these worms (flukes)-- Schistosoma haematobium, S. japonicum, and S. mansoni -- which cause disease in humans. The larval (young) forms of the parasitic worm live in freshwater snails.
