目的评价血吸虫病重点综合治理地区的防治成效,为控制血吸虫病流行提供科学依据。方法按照我国《血吸虫病控制和消灭标准》(GB15976-2006),2009年10月对2004年巍山县、洱源县、大理市和鹤庆县4个实施国家血吸虫病综合治理重点项目县(市)的血吸虫病防治效果进行考核验收。结果 4个县(市)人群IHA检查,阳性率为3.58%～9.70%,粪检人群感染率为0～4.59%;家畜感染率为0～0.31%;活螺密度为0.02只/框,活螺密度为0.09只/框。4县(市)捕获的钉螺全部解剖镜检,均未发现感染性钉螺。结论巍山县、洱源县达到了血吸虫病传播控制标准,大理市和鹤庆县重新达到了传播控制标准。
Objective To evaluate the prevention and cure effects of schistosomiasis in the key integrated control areas and provide a scientific basis for controlling the epidemic of schistosomiasis. Methods According to the national standard of schistosomiasis control and elimination (GB15976-2006), in October 2009, we carried out four national key projects of schistosomiasis control in Weishan County, Eryuan County, Dali City and Heqing County in 2004 City) schistosomiasis control effect of inspection and acceptance. Results The prevalence rates of IHA were 3.58% ~ 9.70% in 4 counties and cities, 0 ~ 4.59% in fecal seizures, 0 ~ 0.31% in domestic animals, and 0.02% in live snails. Loose density of 0.09 / box. 4 counties (cities) captured snails all dissecting microscopic examination, were found not infected snails. Conclusion Weishan County and Eryuan County reached the control standard of schistosomiasis transmission. Dali City and Heqing County again reached the standards of transmission control.
