【摘要】 [目的]了解顺德区人群华支睾吸虫的感染情况,探讨华支睾吸虫病的感染方式、途径等流行病学特征,为大规模开展华支睾吸虫病的防治工作和评价防治效果提供科学依据。[方法]用单纯整群随机抽样方法抽取样本,用改良加藤厚涂片法粪检华支睾吸虫卵并计数。[结果]共调查2100人,发现感染华支睾吸虫为813人,感染率为38.70%。男性感染率46.90%高于女性感染率30.80%,二者间差异有统计学意义(χ2=57.52,P﹤0.05)。各年龄组均有感染,人群感染率随年龄增长而升高,各年龄组华支睾吸虫的感染率差异有统计学意义(χ2=227.195,P﹤0.05)。49.8%的被调查者吃过淡水鱼生,84.3%的家庭刀具、砧板没有生熟分开,人群对华支睾吸虫病相关知识知晓率偏低,对华支睾吸虫病危害重视不足。[结论]顺德区人群华支睾吸虫感染仍属高度流行区,当地群众的不良生活及饮食习惯仍是华支睾吸虫病传播的最主要途径。更多还原

【Abstract】 [Objective] To study the epidemic situation of Clonorchis sinensis in Shunde of district of Foshan in China,and to analyze its prevalent features and provide scientific basis for making effective control measures in Shunde area.[Methods] The investigation sites were selected by simple cluster sampling.Modified Kato-Katz’s thick smear was used to detect the parasite eggs in the feces.The data of infection rate and intensity were analyzed.[Results] A total of 813 cases of Clonorchis infection was found from 2 100 sampled population,and the mean prevalence was 38.70%.The positive rate of infection in male and female was 46.90% and 30.80%,respectively.There was infection in all age groups.It was found that an increase trend of infection rates correlated with age.49.8% of the interviewees had a history of consuming raw fish,and 84.3% of them using the same chopping board for handling both cooked and raw foods.People do not have good knowledge of clonorchiasis and pay no attention to clonorchiasis.[Conclusion] Shunde District is the epidemic region of clonorchiasis.The main route of transmission is the bad life and diets habits.更多还原
