Clonorchis

sinensis Clonorchis sinensis is a parasitic flatworm which primarily infects and feeds on freshwater fish in the East Asia region. It is an important human health concern because it causes a disease known as clonorchiasis, which can lead to severe complications including damage to the liver, biliary tract, and pancreas. It is also associated with the development of cholangiocarcinoma, a cancer of the bile ducts. Effective control strategies for C. sinensis infection include improved sanitation practices, education, and the use of medication. Treatment of clonorchiasis with antiparasitic drugs (e.g. praziquantel) is also recommended.
