湖北省华支睾吸虫病流行病学调查

An Epidemiological Study on Clonorchiosis Sinensis in Hubei Province

１９８７～１９９１年，对湖北省６２个县（市）进行了华支睾吸虫病流行病学调查。在５２个县（市）发现疫源地，３１个人群调查县（市）有２９个查出肝吸虫患者，人群感染率０．１％～１６．２％。发现第一中间宿主淡水螺２科５种；第二中间宿主淡水鱼７科３１种，虾１种。其中５种鱼为第二中间宿主新纪载；保虫宿主６种。人群感染的主要方式是吃半生不熟烤小鱼、口衔鱼等。

n epidemiological study on clonorchiosis sinensis was conducted in 62 counties and cities in HubeiProvince during 1987～1991,and clonorchis sinensis was identified in 52 counties and cities. Humanpopulation studies showed there were patients with clonorchiosis sinensis in 29 of 31 counties and citiesinvestigated, with infection rates of 0.1%～16.2%。 There were five species in two families of freshwaterspiral shells as first intennediate host of clonorchis cinensis, 31 species in seven families of freshwater fish(with five species of fish newly discovered)and one species of freshwater shrimp as second intermediatehost, and six species as reservoir host.Studies revealed holding small fish in the mouth and eatingundercooked roasted fish were two major modes of transmission for clonorchiasis sinensis in the provlnce.
