摘要
目的探讨手部清洁卫生对小学生蛔虫再感染的影响。方法将基线调查中查出的蛔虫感染者给予驱蛔治疗,半月复查阴性者作为观察对象。实验组开展洗手活动,对照组不开展洗手活动,每2个月用Kato法复查1次,连续观察1年。比较实验组与对照组蛔虫累计再感染率,计算相对危险度(RR)及措施保护率(PR)。结果小学生蛔虫累计再感染率从开展洗手活动后第4个月开始实验组低于对照组(P<0.001),手部清洁卫生防止蛔虫感染的效果指数IE=2.25,保护率PR=55.55%。结论保持手部清洁卫生可减少小学生蛔虫再感染。
Objective To approach the impact of hands cleanliness on diminution of Ascaris lumbricoides reinfection in pupils. Methods The pupils who infected A. lumbricoides in basic survey and then turned to negative in half month after treated by albendazole were selected as observation group. Hand-washing activity was conducted in experimental group, but not in control group. The Kato method was done once every two months for one year to compare the reinfection rates in pupils of two groups, then to calculate the index effectiveness(IE) and protective rate(PR). Results From the 4th month after starting of hand-washing activity, the reinfection rates of experimental group were lower than that of control group(P<0.001). The IE of preventing infection of A. lumbricoides was 2.25, PR was 55.55%. Conclusion Keeping hands clean and hygiene will reduce the reinfection of A. lumbricoides.
