摘　　要：目的 了解祁阳县农村居民肠道寄生虫感染现状,为制定肠道寄生虫病防治规划和策略提供依据. 方法 在全县15个镇进行整群随机抽样.采用改良加藤厚涂片法（Kato-Katz）粪检全片粪膜虫卵. 结果 1个行政村调查3周岁以上的常住居民200人以上,调查15个镇21个村3 682人,肠道寄生虫感染总人数755人,总感染率为20.51％;其中肝吸虫感染率16.57％,蛔虫感染率为0.52％,钩虫感染率为2.80％,鞭虫感染率为0.49％,粪类圆线虫感染率为0.14％,男、女性别之间的感染率差异无统计学意义（x2=0.06,P＞0.05）;各年龄组均有感染,且感染随年龄增长而升高,40～60岁组感染率占82.52％,各年龄组差异有统计学意义（x2 =208,P＜0.05）. 结论 祁阳县农村居民土源性寄生虫感染率下降较明显,但少数乡镇肝吸虫感染率仍然维持较高水平,应加大肝吸虫病综合性防控措施的力量,降低农村居民肠道寄生虫感染率.Objective To investigate the current situation of intestinal parasitic infections among rural residents in Qiyang County so as to provide references for developing the planning and strategy of intestinal parasite prevention and control.Method Surveys were conducted among 15 towns selected by cluster random sampling in Qiyang County.A modified Kato-Katz method was used to test dung membrane eggs.Results More than 200 permanent residents over 3 years of age were selected from each administrative village surveyed.A total of 755 residents were tested positive for intestinal parasitic infections among 3,682 permanent residents selected from 21 villages of 15 target towns.The total infection rate was 20.51%,in which the infection rates of clonorchiasis,roundworm,hookworm,whipworm and other nematodes were 16.57%,0.52%,2.80%,0.49%,and 0.14 %,respectively.No statistically significant difference was found regarding the infection rates of the above-mentioned intestinal parasites between males and females（x2 =0.06,P 〉0.05）.The study also showed that the infection rate of each age group increased with their age,and the rate of age group of 40-60 years accounted for 82.52 %,with statistically significant differences among different age groups （x2 =208,P 〈 0.05）.Conclusions The infection rates of soil-transmitted parasitic diseases fall significantly among rural residents in Qiyang County,but clonorchiasis is becoming a serious public health problem in few towns surveyed.It is necessary to strengtheningly implement comprehensive control and prevention measures against clonorchiasis so as to decline the rural residents＇ infection rates of intestinal parasites.
