自1996年5月至8月,在博乐市分别进行了学前儿童、青少年肠道寄生虫本底调查和驱虫复查,共调查2 180人,寄生虫感染者607人,总感染率为27.84％(607/2 180)。查见人体寄生虫10种,以蛲虫感染率为最高16.24％,依次为蓝氏贾第鞭毛虫7.29％,微小膜壳绦虫3.12％,鞭虫1.88％,蛔虫1.56％。集体驱虫的受治率98.33％(22 490/22 873),驱虫后寄生虫感染率为13.60％(288/2 117)。一次集体驱虫后,寄生虫总感染率下降了51.15％,其中蠕虫、原虫和绦虫感染下降率依次分别为61.73％,23.52％和20.25％,表明对肠道蠕虫的驱虫效果显著,取得了明显的社会效益。
From May to August 1996, two pre-school children and adolescents were enrolled in the study. The total number of parasites was 2 180 and 607 parasites were infected. The total infection rate was 27.84 % (607/2 180). 10 species of human parasites were found. The highest infection rate of pinworm was 16.24%, followed by 7.29% of Giardia lamblia, 3.12% of tapeworm, 1.88% of whipworm and 1.56% of roundworm. The rate of collective deworming was 98.33% (22 490/22 873), and the rate of parasite infection after deworming was 13.60% (288/2 117). After a collective deworming, the total parasitic infection rate dropped by 51.15%, of which worm, protozoan and tapeworm infections decreased by 61.73%, 23.52% and 20.25%, respectively, indicating that the deworming effect on intestinal worms was remarkable and achieved Obvious social benefits.
