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。
Objective To evaluate the control effect of the control standard of schistosomiasis in Yunnan Province so as to provide a scientific basis for making the next prevention and control strategy. Methods The surveillance reports and annual reports of schistosomiasis surveillance in Yunnan Province from 2009 to 2012 were collected, and the prevalence and characteristics of schistosomiasis were analyzed. Results The province’s schistosomiasis epidemic index decreased. Compared with 2009, the adjusted infection rate of schistosomiasis decreased by 33.33% in 2012 and 55.56% in the village. The positive rate of livestock droppings decreased by 45.45% and that in diseased cattle villages decreased by 42.25%. The area of snails with real snails decreased by 13.58% %, Live lobe density decreased by 25.66%, no further detection of schistosomiasis snail in 2012. Conclusion There are still human and animal schistosomiasis infection in some areas in Yunnan Province, and it is difficult to reach the standard of blocking schistosomiasis transmission in short term.
