为了解浙江省宁海县人群华支睾吸虫感染现状、疫源地及人群知晓情况,于2016年随机抽取跃龙、胡陈、岔路、深圳、力洋等5个乡(镇)各1个附近地域有溪流的行政村作为调查点,采集3周岁以上人群和保虫宿主犬粪样,采用改良加藤厚涂片法检测华支睾吸虫感染情况;采集第二中间宿主麦穗鱼(Pseudorasbora parva),取鱼脊背部肌肉用直接压片法观察囊蚴感染情况;每村随机抽取送检人群30人进行问卷调查.结果显示,共采集5个村1 034份人粪样和25份犬粪样,均未发现华支睾吸虫感染;采集麦穗鱼381条,华支睾吸虫囊蚴感染率13.39％ (51/381).知晓调查共150人,回收有效问卷145份,人群华支睾吸虫病防治知识的知晓率为13.10％ (19/145);日常生活中生熟菜板分开使用的人群占46.21％ (67/145),平时食生、半生淡水鱼虾的人群占7.59％ (11/145);4.14％ (6/145)的被调查者回答愿意尝试食生鱼片,82.76％ (120/145)的人群表示得了华支睾吸虫病后愿意花钱买药驱虫,2.76％ (4/145)的人群表示治好华支睾吸虫感染后想要继续食生或半生的淡水鱼虾.提示麦穗鱼中有一定的华支睾吸虫的感染率,人群知晓率低且行为生活习惯存在高危行为,应倡导健康饮食方式.“,”This study aimed to understand the current status of Clonorchis sinensis infection in Ninghai County,the place of infection,and the knowledge and practice among the general population in Ninghai County,in order to evaluate the spread of the disease.Five towns namely Yuelong,Chalu,Shenzhen,Liyang,and Huchen were randomly selected for survey.One administrative village with streams nearby was selected from each of the towns for sampling feces from humans aged above 3 and from dogs.The modified Kato thick smear method was used to examine eggs of C.sinensis.The second intermediate host fish (Pseudorasbora parva) was also sampled to examine metacercaria in muscles on the back using the tabletting method.The knowledge and practice survey was performed on 30 randomly selected persons in each village.The results showed that among 1 034 human and 25 dog feces in 5 villages,no C.sinensis eggs were found.Of the 381 P.parva collected,the metacercariae rate was 13.39％ (51/381).The knowledge and practice survey was performed on 150 people,and 145 valid questionnaires were returned.The awareness rate of clonorchiasis prevention was 13.10％ (19/145),46.21％ (67/145) reported separate use of raw and cooked dishes,7.59％ (11/145) usually ate raw,half-cooked fish and shrimp,4.14％ (6/145) expressed the willingness to take a try of raw fish,82.76％ (120/145) would choose to buy anthelmintics if infected,and 2.67％ (4/145) would not quit the raw or half-raw fish or shrimp diet after remedy of the disease.These results imply a predisposition to infection from P.parva,a low awareness rate of C.sinensis infection among the general population,and a high risk of infection arising from lifestyles.Therefore,healthy diet and lifestyle should be advocated.
