云南省人体肠道线虫病防治试点的研究

STUDY ON HUMAN INTESTINAL NEMATODIASIS CONTROL IN PILOT AREAS OF YUNNAN PROVINCE

１９９２～１９９５年，我们以澄江县大河口乡５个自然村为试点开展了人体肠道线虫病防治研究工作。从１９９２年秋季起，试点区除第１、２次服药仅对线虫卵阳性者外，人群每年春、秋两次服用阿苯达唑。３年后与防治前相比，该人群的肠道线虫总感染率下降了４７．２７％，其中蛔虫感染率下降７５．９７％，鞭虫感染率下降７０．３４％；在最后１次人群的粪检中未检出钩虫卵及蛲虫卵，表明防治研究工作收到了良好的效果。

Human intestinal nematode control have been studied in pilot areas of 5 natural villages of Dahekou Town in Chengjiang County of Yunnan Province from 1992 to 1995. Mass drug administration was conducted with albendazole 400 mg per man twice a year. After 3 years, the overall infection rate of human intestinal parasites decreased by 19.65%(62.75%-33.10%), and the infection rates of Ascaris lumbricoides and Trichuris trichiura decreased by 32.57%(42.87%-10.3%) and 10.22 %(14.53%-4.31%) respectively. In addition, eggs of Hookworm and Enterobius vermicularis weren't found in the last fecal examination. The result showed that this method is effective for human intestinal nematode control.
