In such cases, the infection follows the ingestion of undercooked or pickled freshwater fish imported from one of the endemic areas and containing metacercariae. Diagnosis
Adult C. sinensis worms can inhabit the bile ducts of humans for 20–25 years without any clear clinical symptoms. This, in addition to the nonspecific symptoms infected persons may develop, can lead to missed diagnoses.Patients are diagnosed when C. sinensis eggs are found in stools. The formalin-ether concentration technique (FECT) method of stool examination is most effective at diagnosing light cases of infection, while the Kato-Katz (KK) method is more suitable for the diagnosing of persons with clonorchiasis. Serological methods that use enzyme-linked immunosorbent assay (ELISA) can help differentiate the eggs of C. sinensis from other flukes. Treatment
Praziquantel is the treatment of choice for clonorchiasis. References
