Abstract: Objective Objective To understand the current status of intestinal helminth infections in Dafeng City. Methods Methods The resi? dents in 5 villages of Dafeng City were investigated，and their stool samples were detected for the eggs of helminth with Kato? Katz technique，and Enterobius vermicularis was detected by the cellophane anal swab method. Results Results The total infection rates of intestinal helminth were 5.77%，5.51%，4.60%，4.18%，3.41%，and 1.38% from 2005 to 2010，respectively. The trend of total infection rates declined year by year. The infection rates in the 20?30 age?group and 60?80 age?group were higher than those in other age?groups. The infection rates of the male and female were 5.63％（359/6 375）and 2.42％（144/5 949），re? spectively，and there was a significant difference（χ2 =74.81，P=0.00） . The infection rate（11.70%）in the northern areas of Dafeng City was higher than that in other places，and the trend of the infection rates decreased from the eastern and northern to the western and southern. The infection rate of E. vermicularis was 1.75% in children in 2010. Conclusions Conclusions The infection rate of intestinal helminth is low，but E. vermicularis infection is relatively general in the children in Dafeng City. Therefore，the pre? vention and treatment still need to be strengthened

摘要： 目的 目的 了解大丰市居民肠道蠕虫感染现状。 方法 方法 选择大丰市5个村为监测点。采用Kato?Katz法检查蠕虫 感染， 采用透明胶纸肛拭法检查儿童蛲虫感染。结果 结果 2005-2010年监测点居民肠道蠕虫感染率分别为5.77%、 5.51%、 4.60%、 4.18%、 3.41%、 1.38%， 呈逐年下降趋势。除2010年未查出蛔虫感染者外， 其余年份均查出钩虫、 蛔虫、 蛲虫感染 者。感染率以20～30岁及60～80岁年龄组较高， 12～20岁及40～60岁年龄组较低。其中20～30岁与12～20岁组、 60～80岁与40～60岁组感染率差异均有统计学意义 （χ2 = 62.24， 71.35， P均＜0.05）。男性感染率为5.63％ （359/6 375）， 女性感染率为2.42％ （144/5 949）， 差异有统计学意义 （χ2 = 74.81， P＜0.05）。北部地区感染率较高， 年间最高为11.71%； 感染率从东、 北到西、 南呈下降趋势。2010年儿童蛲虫感染率为1.75%。结论 结论 大丰市人群肠道蠕虫感染率较低， 需加 大儿童蛲虫感染防治力度。
