Humans and other animals become infested with the Chinese liver fluke by consuming raw or undercooked fish that are contaminated with the parasites. Thus, it is in areas where cooking seafood is uncommon that the highest rates of infection exist. Currently, millions of people are believed to suffer from Chinese liver fluke infection, known as clonorchiasis, but with varying degrees of symptoms. Abdominal pain and digestive problems are fairly frequent occurrences, but only severe cases are accompanied by jaundice, fibrosis, and enlargement of the liver. The most common method of treating those that have been diagnosed with clonorchiasis is administration of Praziquantel but, as the saying goes, prevention is the best cure.
