摘要
目的了解浙江省西部丘陵区华支睾吸虫病的流行现状和流行因素。方法以多阶段整群随机抽样的方法,在浙江省西部4个县(区)20个镇对1530名常住居民进行面对面问卷调查,并对其中1505人用ELISA法检测华支睾吸虫抗体。同时调查第二中间宿主华支睾吸虫囊蚴感染情况。结果人群血清抗体阳性率为0.67%。87.0%的居民不知道生食淡水鱼虾会感染华支睾吸虫,14.1%的居民有生食淡水鱼虾史。检测第二中间宿主20种鱼虾2812尾,其中12种鱼虾感染华支睾吸虫,囊蚴感染率为6.7%。结论浙西丘陵区华支睾吸虫感染率不高,但依然存在感染风险,需进一步加强健康教育。
Objective To understand the prevalence of clonorchiasis sinensis and related factors among residents in western hilly area of Zhejiang province.Methods A total of 1530 residents in 20 townships selected by multi stage stratified cluster sampling received questionnaire survey,and blood samples were taken from 1505 of them to detect clonorchis sinensis antibody with ELISA.The infection of metacerearia of clonorchis sinensis in second intermediate hosts were detected too.Results The overall antibody positive rate was 0.67% in human.Up to 87.0% of people surveyed did not know that the disease can be acquired through eating raw fish and 14.10% of them had history of eating raw fish.A total of 20 kinds of fish/shrimp were detected,and the infection rate in these second intermediate hosts was 6.7%.Conclusion The prevalence of clonorchiasis sinensis was low in human in western Zhejiang,but the risk of infection still exists.The health education needs to be further strengthened.
