Research Abstract

Opisthorchis viverrini (O. viverrini) infection was found in 31 villages in 35 surveyed villages. There were high prevalent villages especially in the south part of Kampong Cham province where there were more than 70% of egg positive rate. Raw fish dishes were served as traditional foods which villagers enjoyed. Both cercariae and metacercariae were found from the intermediate hosts of snails and fresh water fish respectively in the surveyed areas. The infection cycle of O. viverrini was therefore established in these villages.
For the first time villagers and local government health staffs learned about O. viverrini infection and the risks these areas had from the spreading of the infection. It was important to encourage them to join the research process, to report their own results and to provide health education to further understand their own health problems and think prevent measures.
