Fasciola Hepatica infection is called fascioliasis. A worm bug interferes with the host's digestive system and can cause diarrhea. Migration of the worms through the liver can also cause bleeding, which can cause anemia and sudden death, especially in ruminant animals such as cattle and sheep. Human infections are rare, but worms can live and breed in human bile ducts for 10 years or more, causing health problems. Symptoms include fever, anemia and swelling of the liver. Worms can enter the throat of an infected person and cause respiratory problems. Fascioliasis in humans can be treated, after being diagnosed.
Prevention
Animals or humans infected with liverworms should be treated with anti-parasite drugs three times per year, to suppress the various stages of development of the liverworm. Liverworms can die in the cooking process; humans can avoid fascioliasis by not eating raw foods.
Extra attention should be taken in processing raw snails, including hand washing and skin surface sterilization after contact with raw snails.
