学龄前儿童蛲虫病的流行现状与防治

采用透明胶纸拭肛法对徐州城乡38所幼儿园共9297名儿童进行蛲虫流行情况调查,结果发现蛲虫卵阳性者3223名(34.7％)。对其中12所共2660名儿童中阴性者再连续检查两天次,累计阳性率达55.4％。城、乡以及男、女性别儿童感染率均无显著性差异(P＞0.05)。3～6岁间,年龄与感染率呈显著正相关(r＝0.998,P＜0.025)。感染者的手指、内裤、床单和坐椅上均查到感染性卵。52.7％感染者具有肛痒症状。表明蛲虫病在我区城乡儿童中流行广泛、危害严重,急待防治。对2358名感染者分别采用不同剂量丙硫咪唑与复方甲苯达唑治疗,虫卵阴转率达97.7％～98.9％,效果显著,副反应轻微。表明这两种药小剂量顿服,适用于现场普治,值得推广应用。
