江西省信丰县华支睾吸虫病和防治相关知识知晓情况调查

目的 了解江西省信丰县华支睾吸虫病和防治相关知识知晓情况，为开展华支睾吸虫病防治工作提供科学依据。方法 以吃“鱼生”习惯为线索调查信丰县华支睾吸虫病潜在流行区，2016年开展人群粪检，并检测淡水鱼囊蚴及淡水贝类雷蚴、尾蚴，同时检查猫、犬和猪等保虫宿主粪便。对华支睾吸虫病防治知识知晓情况进行问卷调查。 结果 信丰县26个村的居民有生食淡水鱼习惯，吃“鱼生”者占调查人数的19.51%，其人群平均华支睾吸虫感染率为21.56%，纹沼螺华支睾吸虫感染率为0，淡水鱼华支睾吸虫感染率为8.24%，保虫宿主华支睾吸虫平均感染率为2.27%。人群华支睾吸虫感染率随年龄升高而呈现上升的趋势，吃“鱼生”与人群华支睾吸虫感染率呈正相关（r = 0.88，P < 0.01）。仅有11.46%的调查对象了解吃“鱼生”会感染华支睾吸虫，知道华支睾吸虫对身体有危害者仅占5.28%。 结论 信丰县5个乡（镇）26个村为华支睾吸虫病流行区；加强华支睾吸虫病危害和感染途径的健康教育、逐步改变居民吃“鱼生”的习惯是控制当地华支睾吸虫病流行的根本措施。

Epidemiological survey on clonorchiasis and awareness of prevention and control knowledge in Xinfeng County of Jiangxi Province

Objective To understand the epidemic status of clonorchiasis and awareness of prevention and control knowledge in Xinfeng County of Jiangxi Province， so as to provide the evidences for control measures. Methods The baseline survey was carried out with a clue investigation of raw?fish eating behavior in potential endemic areas in 2016. The residents were examined by stool tests. The metacercariae of Clonorchis sinensis in fish， the rediae and cercariae in freshwater mollusk were detected. The feces samples of cats， dogs and pigs were collected and examined by sedimentation technique. Meanwhile， the epidemic factors， health knowledge and behavior were also surveyed. Results The residents in 26 villages had the habit of eating raw freshwater fish， and 19.51% of the respondents had this habit. The average infection rates of the population， Parafossarulus striatulus， freshwater fishes and reservoir hosts were 21.56%， 0， 8.24% and 2.27%， respectively. The infection rate of the population increased with age. There was a significant positive correlation between the behavior and the infection rate of the population （r = 0.88， P < 0.01）. Only 11.46% of the respondents knew that eating raw?fish might cause C. sinensis infection， and 5.28% of them knew that C. sinensis was harmful to health. Conclusions Twenty?six villages in five townships were endemic areas of clonorchiasis in Xinfeng County. The permanent solution of prevention and control of clonorchiasis is to strengthen the health education and change the habit of raw?fish eating gradually.
