1994～ 1996年 ,在 117万 2周岁以上的居民中 ,每年 1次用甲苯咪唑或阿苯达唑每人 40 0 m g,2 d分服 ,人群平均年服药率为 6 0 .41% ,按整群分层随机抽样 ,用 Kato- Katz法比较服药前后人群肠道线虫感染率 ,结果总感染率下降了 80 .5 6 % ( 1989年为 79.97% ,1997年为 15 .5 5 % ) ;钩虫、蛔虫、鞭虫的感染率分别下降了 78.76 %、93.5 8%和 89.0 4% ;多虫感染率下降了 96 .93%。表明在肠道线虫重感染区 ,采用甲苯咪唑或阿苯达唑定期群体化疗驱虫 ,是一项方便、安全、有效良好的控制措施
From 1994 to 1996, among the residents who were over 1,120,000 years of age, the average annual rate of taking the drug was 40.0 mg and 2 0 d every year with mebendazole or albendazole 60.0% The whole population was stratified by random sampling. The infection rate of gut nematodes before and after administration was compared by Kato-Katz method. The total infection rate decreased by 80.56% (79.97% in 1989 and 15.55% in 1997). The infection rates of hookworm, roundworm and whipworm decreased by 78.76%, 93.58% and 89.0% respectively. The infection rate of multi-worm decreased by 96.93%. Indicating that in the gut nematode infection area, the use of mebendazole or albendazole periodic group chemotherapy repellent is a convenient, safe, effective and good control measures
