Abstract: Objective To evaluate the effect of schistosomiasis control in Yunnan Province since achieving the transmission control standards，so as to provide the evidence for formulating the next prevention and control strategy. Methods The schistoso? miasis epidemic monitoring reports，annual reports，relevant information about Oncomelania hupensis snails，and schistosomiasis patient conditions were collected and analyzed for epidemic condition and characteristics of schistosomiasis in Yunnan Province from 2009 to 2012. Results The various epidemic monitoring indicators all decreased. In 2012，compared with 2009，the preva? lence reduced by 33.33% after correction；the number of villages with schistosomiasis patients reduced by 55.56%；the adjusted positive rate of livestock stool tests reduced by 45.45%；the number of villages with infected cow reduced by 42.25%；the actual area with snails reduced by 13.58%；the density of living snails reduced by 25.66%，and no schistosome infected snails were found in 2012. Conclusion There still exist schistosome infections in human and animals in some local areas of Yunnan Prov? ince，and it is difficult to achieve the standard of schistosomiasis transmission interrupted in a short period.

摘要： 目的 目的 评价云南省达到血吸虫病传播控制标准以来的防治效果， 为制定下一步防控策略提供科学依据。方法 方法 收集2009-2012年云南省血吸虫病疫情监测报表、 年报表， 以及有关螺情、 病情等资料， 分析血吸虫病流行状况和特点。结 结 果 果 全省各项血吸虫病疫情指标有所下降。2012年与2009年相比， 人群血吸虫校正感染率下降了33.33%， 发现有病人村 减少55.56%； 家畜粪检阳性率下降了45.45%， 有病牛村减少42.25%； 实有钉螺面积下降13.58%， 活螺密度下降25.66%， 2012年未再查到血吸虫感染性钉螺。结论 结论 云南省局部地区仍存在人畜血吸虫感染， 短期内难以达到血吸虫病传播阻断 标准。
