Fascioliasis is a parasitic infection caused by Fasciola hepatica, also known as the “common liver fluke” or the “sheep liver fluke”. People typically become infected from eating raw watercress, eating water plants contaminated with the parasite, or by drinking or using contaminated water. Fascioliasis is especially common in places where sheep or cattle are raised. In the early phase, symptoms include nausea, vomiting, and abdominal pain or tenderness. Fever, rash, and difficulty breathing can also occur during this stage. In the later stage, the symptoms continue and can also include inflammation of the liver, gallbladder, and pancreas. Effective treatment is available to treat fascioliasis.
