浙江省人体土源性线虫病调查及防治效果分析

Survey of prevention and treatment of human intestinal parasitic diseases in Zhejiang

目的根据2009年人体土源性线虫病调查结果以及历史数据资料,分析浙江省土源性线虫病防治成效。方法采用加藤厚涂片法和透明胶纸肛拭法检测土源性线虫。结果 2009年调查共检测10 307人,检出蛔虫、钩虫、鞭虫、蛲虫4种寄生虫虫卵,虫卵阳性人数为162人,感染率为1.57%。1999年较1989年寄生虫感染率下降71.51%,2004年较1999年下降67.25%,2009年较2004年下降79.01%。结论 1989-2009年间,浙江省人体土源性线虫总体感染率呈明显下降趋势。在总感染率较低的情况下,仍需继续采取适当、可行的防制策略以降低城市儿童蛲虫和农村居民钩虫感染。

Objective To analyze the effectiveness of prevention and treatment of human intestinal parasitic diseases in Zhejiang according to the survey result in 2009 and historical data. Methods Kato thick smear method and transparent adhesive tape anal swab method were used to detect human intestinal parasitic worms. Results A total of 10 307 people were surveyed. 162 were found to be positive with roundworm, hookworm, whipworm or pinworm eggs, and the infection rate was 1.57%. The infection rate declined by 71.51% from 1989 to 1999, 67.25% from 1999 to 2004 and 79. 01% from 2004 to 2009 ,respectively. Conclusion From 1989 to 2009 ,the overall prevalence of intestinal parasitic diseases in Zhejiang declined obviously, but it is still necessary to take appropriate and feasible control strategies to reduce the infection rate of pinworm in urban children and the infection rate of hookworm in rural residents
