摘要： 【摘要】 目的  分析铜陵县血吸虫病疫情，为科学制定“十三五”血吸虫病防治规划提供依据。 方法  收集2004~2013年全县防治工作开展情况和人畜病情、螺情等疫情资料，进行综合分析。 结果  2004年以来，全县血吸虫病疫情呈现下降趋势。2013年底全县钉螺面积为2 476.17hm2，较2004年下降了23.05%；有螺环境数182个，较2004年下降了24.48%；人群病原学检查阳性率从2004年的7.55%下降至2012年以后查不出阳性；耕牛感染率从2004年的8.5%降至2011年以后查不出感染牛。2007年全县达疫情控制标准，2010年以后全县无急性血吸虫病疫情发生，2011年以后全县未发现感染性钉螺，2012年全县达血吸虫病传播控制标准。 结论  2004年以来，通过采取传染源控制为主的血吸虫病综合防治措施，铜陵县血吸虫病疫情降到历史最低水平，血吸虫病传播得到有效控制，但仍存在较大面积钉螺分布环境，疫情存在反弹风险，应继续加强血吸虫病防治工作。

Abstract:

【Abstract】 Objective  To analyze the endemic situation of schistosomiasis in Tongling County in order to provide scientific evidences with schistosomias control program in the coming the “13th Five-year Plan”. Methods The data were objectively collected and statistically summarized regarding the control achievement in schistosomiasis, population and domestic animal infection status and presence of Oncomelania hupensis in Tongling county during 2004 and 2013. Results Prevalence of schistosomiasis generally tended to decline since the program started in 2004. By the end of 2013, the area infected with Oncomelania hupensis was 2 476.17hm2, and environment with snail presence was 182, which was decreased by 23.05% and 24.48%, respectively, compared to those in 2004 throughout the county. Etiological tests revealed that the positive population was free in 2012 from a rate of 7.55% in 2004, and positive domestic animals were absent in 2011 from 8.5% infection in 2004. Infection control of schistosomiasis reached the criteria in 2007. No acute case of schistosomiasis occurred in 2010, and infectious snails were free in 2011. By 2012, control of the schistosomiasis transmission was overall up to the criteria across the county. Conclusion By comprehensive control of the infection sources, prevalence of schistosomiasis has effectively been brought down to the lowest level in history in Tongling County after 2004. However, there still exists a large scale of snail areas in marshland, indicating that the endemic situation is likely to rebound, which still needs close surveillance and risk assessment in following tasks.
