为调查全县中、小学生肠道蠕虫感染情况,研究发病规律和防治措施。我们于1982年对城镇与农村三所中、小学1,387名学生,收集粪便标本,采用饱和盐水漂浮法一次镜检,查常见肠道蠕虫钩虫、蛔虫、鞭虫,发现虫卵者为阳性。 结果表明钩虫、蛔虫、鞭虫感染率分别为21.19、46.79和58.26％。其中男生钩虫与鞭虫感染率分别为24.04和56.97％,女生分别为16.94和60.18％,两者比较(钩虫x~2=10.05,P<0.01;鞭虫x~2=14.09,
In order to investigate the county, primary intestinal worm infection, study the incidence of disease and prevention measures. We collected 1,387 stool samples from 1,387 primary and secondary schools in urban and rural areas in 1982 and screened them by a saturated salt water floatation method. The common intestinal worm hookworms, roundworms and whipworms were found to be positive. The results showed that hookworm, roundworm, whipworm infection rates were 21.19,46.79 and 58.26%. The prevalence of hookworm and whipworm in boys was 24.04 and 56.97% respectively, and girls were 16.94 and 60.18% respectively (hookworm x 2 = 10.05, P <0.01; whipworm x 2 = 14.09,
