目的分析2005~2014年巢湖市血吸虫病监测村疫情变化,为制订本市血吸虫病防治策略提供参考依据。方法按照《安徽省血吸虫病监测方案》要求,每年在监测村开展人畜查治病、查灭螺和相关因素监测,并对10年间病情和螺情指标进行统计分析。结果监测村连续10年未发生急性感染病例、未查出当地新感染病例、未查出阳性耕牛;2010年查出回升和新发钉螺面积共计10 150m~2,未查出感染性钉螺,活螺密度和活螺框出现率为5.43只/0.11m~2和50.5%,到2012年分别下降90.79%和77.37%,2013年、2014年监测村内有螺环境未查出活螺。结论巢湖市采取的防治措施成效显著,但是丘陵地带螺情监测仍需继续加强。
Objective To analyze the epidemic situation of schistosomiasis surveillance in Chaohu from 2005 to 2014 and provide reference for the prevention and control of schistosomiasis in this city. Methods According to the requirements of “Anhui schistosomiasis surveillance program”, annual monitoring and investigation of human and livestock diseases were conducted in the monitoring villages, and surveillance of snails and related factors were investigated. Statistical analysis was made on the indicators of illness and snail disease in 10 years. Results There was no case of acute infection in the monitoring village for 10 consecutive years, no new case of local infection was found, and no positive cattle were found. In 2010, the area of newly recovered snails and newly found snails was found to be 10 150 m ~ 2. Infectious snails were not detected, The live lobe density and live screw lobe appearance rate was 5.43 /0.11m ~ 2 and 50.5%, down 90.79% and 77.37% respectively in 2012, and in 2013 and 2014, there was no live snail detected in the snail environment in the village. Conclusion The prevention and cure measures taken in Chaohu City have achieved remarkable results. However, the monitoring of snails in the hilly areas still needs to be further strengthened.
