Opisthochiasis from imported raw fish

Abstract

Liver fluke infection caused by Opisthorchiidae is a major public health problem in many parts of the Far East, Southeast Asia, and eastern Europe. However, with the growing volume of international travel and population migration, the infection is increasingly diagnosed in countries where the disease is not endemic, particularly in North America. We report an outbreak of acute opisthorchiasis in a family that was infected in a non-disease-endemic area after eating raw carp illegally imported from a highly disease-endemic area in Siberia. With the growing numbers of former Soviet Union citizens immigrating to other countries, western physicians need to be alert regarding Opisthorchis-associated pathology in this population. The epidemiology and biology of Opisthorchiidae in the former Soviet Union are reviewed.
