目的了解大丰市居民肠道蠕虫感染现状。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 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。
Objective To understand the status of intestinal worm infection in residents of Dafeng City. Methods Five villages in Dafeng City were chosen as monitoring points. Kato-Katz method to check the worm infection, the use of transparent adhesive tape Anal swab infection check children. Results The rates of intestinal helminth infection in residents at monitoring points from 2005 to 2010 were 5.77%, 5.51%, 4.60%, 4.18%, 3.41% and 1.38%, respectively, showing a declining trend year by year. In addition to 2010 did not detect Ascaris infection, the remaining years were detected hookworm, roundworm, pinworm infection. The infection rate was higher in the age groups of 20-30 years and 60-80 years old, lower in the age group of 12-20 years and 40-60 years. The infection rates of 20-30 years old and 12-20 years old group, 60-80 years old and 40-60 years old group were all statistically significant (χ2 = 62.24, 71.35, P <0.05). The infection rate of males was 5.63% (359/6 375) and the infection rate of females was 2.42% (144/5 949). The difference was statistically significant (χ2 = 74.81, P <0.05). In northern areas, the infection rate was high, up to 11.71% during the year. The infection rate showed a downward trend from east to north to west and south. In 2010, the prevalence of pinworm in children was 1.75%. Conclusion Dafeng City, the lower the rate of intestinal helminth infection, children need to increase the prevention and control of pinworm infection.
