Field survey for Opisthorchiasis in Cambodia

灵猫后睾吸虫（Opisthorchis viverrini）。在35个被调查的村庄中有31个村庄发现了禽流感（viverrini）感染。在磅湛省南部有高流行村，虫卵阳性率超过70%。生鱼片是村民们喜欢吃的传统食物。在调查区钉螺中间宿主和淡水鱼中间宿主均发现有尾蚴和囊蚴。O.村民和当地政府的卫生人员第一次了解到O.以及这些地区因感染蔓延而面临的风险。应鼓励他们参与研究过程，报告自己的研究结果，并提供健康教育，以进一步了解自己的健康问题，并思考预防措施。

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.
