摘　　要：目的 了解江苏省金湖县肠道线虫流行趋势,为今后防治策略提供科学依据。方法 2003-2012年,每年选择2个镇,每镇随机选取1个村,每村整群调查2岁以上常住居民500人。采用改良加藤厚涂片法（Kato-Katz法）1送2检检测肠道线虫卵,统计人群感染率、单虫感染率和感染度。对调查对象性别、年龄、职业等相关因素进行调查。结果 2003-2012年共监测调查当地居民10 716人,肠道线虫感染率在0.20%-4.30%,平均感染率为1.42%。以钩虫感染为主,占感染者的76.25%。未发现肠道线虫多重感染和重度感染者,男性感染率为1.11%,女性感染率为1.69%,差异有统计学意义（χ^2=6.48,P〈0.05）。女性钩虫感染率高于男性,差异有统计学意义（χ^2=11.43,P〈0.01）。各年龄组和各职业人群均有肠道线虫感染,差异无统计学意义。结论 金湖县肠道线虫感染率维持在一较低水平,仍应继续采取对重点人群驱虫服药为主的综合性防治措施,以进一步降低人群肠道线虫感染率。Objective To investigate the epidemic trend in Jinhu county, Jiangsu province for providing reference for prevention and control strategies. Methods During 2003 -2012, two townships were chosen and one village was chosen from each township, and 500 residents were sampled in each village with clustering methods. The Kato- Katz method was adopted to test the intestinal nematode eggs. The infection rate, single infection rate and the degree of infection were statistically analyzed. Results During 2003 - 2012, a total of 10 716 residents were surveyed, with the infection rate ranged in 0. 20 -4.30% and the mean infection rate was 1.42%. The infection was majorly hookworm infection, accounting for 76.25%. No multi -infection and se- vere infection was detected. The infection rate of male and female was respectively 1.11% and 1.69%, with statistical difference （χ^2 = 6. 48, P 〈 0. 05 ） and the hookworm infection rate was higher in female than in male （χ^2 = 11.43, P 〈 0. 01 ）. No statistical difference was tested among different age groups and occupation groups. Conclusion The infection rate stays at a relatively low level, yet comprehensive prevention and control measures still need to be implemented on the vulnerable population to further lower the infection rate.
