本文报告1964—1980年对哈尔滨市区及郊县农村儿童肠道线虫感染情况的几次调查结果。用胶玻纸拭法检查一次,幼儿园儿童和中小学生的蛲虫总阳性率为52.50％,农村小学生的蛔虫感染率为78.07％。中学生蛔虫感染率60.0％。市区先后两次蛲虫感染情况调查时间相隔16年,感染率未见明显差别,似说明此虫感染率如不采取防治措施并不随生活水平提高而自然下降。蛔虫感染则不同,14年后调查一郊县农村小学,学生蛔虫感染率明显降低。市区某校小学生蛔虫感染率20.83％。城乡儿童蛲虫感染率差别不明显,年龄以4—15岁感染率较高,男女两性感染率无显著差异。农村学生蛔虫感染有随年龄增加而感染率下降的趋势,女中学生较男中学生感染率高。几次调查只发现鞭虫感染两例。用药驱蛔,该市农村小学生排虫者多数每人排虫1—5条,平均每人排虫7.4条。肛拭前受检者大便已否对蛲虫检查结果似无重大影响。
This article reports the results of several surveys of intestinal nematode infections in rural children in urban and suburban areas in Harbin from 1964 to 1980. With a plastic glass swab inspection once, kindergarten children and primary and secondary puppets total positive rate was 52.50%, rural primary school ascaris infection rate was 78.07%. Ascaris infection rate of 60.0% in middle school students. In the urban area, the infection rates of pinworms twice in succession were 16 years apart. No significant difference was found in the infection rates. It seems that the infection rate of this worm does not naturally decline with the improvement of living standards. Ascaris infection is different, 14 years after the survey of rural primary schools in rural counties, students significantly reduce the infection rate of roundworms. School students in a school roundworm infection rate of 20.83%. There was no significant difference in the prevalence of pinworm between urban and rural children, with a higher prevalence of infection at 4-15 years old between men and women. There was no significant difference in infection rates between men and women. Ascaris infection in rural students with the increase of age and the infection rate of decline, female middle school students than male high infection rate. Several investigations found only two cases of whipworm infection. Medication driving roundworm, the city’s rural primary school students ranked the most worms rowworm 1-5, an average of 7.4 per row of worms. Anal swab before the subject stool has no significant effect on pinworm examination results.
