[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。
[Objective] To understand the prevalence of Clonorchis sinensis in the population of Shunde District and to explore the epidemiological characteristics of Clonorchis sinensis infection methods, ways and so on, and to provide scientific information for the prevention and control of Clonorchis sinensis on a large scale in accordance with. [Method] Samples were taken by a simple cluster random sampling method, stool samples of Clonorchis sinensis were counted and stained with modified Kato thick smear method. [Results] A total of 2,100 people were investigated, and 813 were found to have infected Clonorchis sinensis with an infection rate of 38.70%. The infection rate of males was 46.90% higher than that of females (30.80%), the difference was statistically significant (χ2 = 57.52, P <0.05). The infection rates in all age groups increased with age. The infection rates of Clonorchis sinensis in each age group were significantly different (χ2 = 227.195, P <0.05). 49.8% of the respondents ate freshwater raw fish, 84.3% of household knives, chopping board without raw and cooked, the crowd knowledge of Clonorchiasis related knowledge is low, insufficient attention to the harm of Clonorchiasis sinensis. [Conclusion] Clonorchis sinensis is still a highly endemic area in Shunde district. The bad habits and eating habit of local people are still the most important ways to spread Clonorchis sinensis.
