【摘要】：目的分析2004-2014年安徽省血吸虫病疫情动态变化,为制订"十三五"血吸虫病防治规划提供参考依据。方法收集2004-2014年安徽省血吸虫病防治信息资料、疫情监测资料,分析全省血吸虫病疫情变化。结果安徽省钉螺面积自2004年以来呈波动上升趋势,至2011年达到最高近3.1亿m2;自2012年起钉螺面积开始下降,2012年钉螺面积较2011年下降了10.55%,2014年钉螺面积降低到近10年来最低水平。2004-2008年全省钉螺密度处于波动状态,2008年以后全省钉螺密度总体呈下降趋势,自2011年起钉螺平均密度均1只/0.1 m2。2004-2011年全省钉螺感染率呈现波动徘徊状态,2012年钉螺感染率迅速下降,2013、2014年连续2年未发现感染性钉螺。2004-2014年人群血吸虫感染率呈现逐年下降趋势,2006年以后各年份急性血吸虫感染人数均在50例以下,且病例呈散在分布,2013、2014年全省无急性血吸虫感染发生。2004-2011年家畜血吸虫感染率均1%,2012年快速下降至0.55%,2014年家畜感染率首次低于同期人群血吸虫感染率。2011年以后,全省血吸虫病传播控制达标进程加速,2012-2014年全省血吸虫病传播控制达标县(市、区)数分别为4、9、14个,乡(镇)数分别为33、76个和32个。结论安徽省血吸虫病防治工作取得显著成效,但巩固成果乃至阻断血吸虫病传播的任务仍很艰巨。
[Abstract]:Objective to analyze the dynamic changes of schistosomiasis epidemic situation in Anhui Province from 2004 to 2014, and to provide reference for formulating the 13th five-year Plan for schistosomiasis control. Methods the information and surveillance data of schistosomiasis control in Anhui Province from 2004 to 2014 were collected and the changes of schistosomiasis epidemic situation in Anhui Province were analyzed. Results the area of Oncomelania hupensis in Anhui Province fluctuated and increased since 2004, and reached the highest level of nearly 310 million m2 in 2011. Since 2012, the snail area began to decline, the snail area in 2012 decreased by 10.55% compared with 2011, and the snail area decreased to the lowest level in nearly 10 years in 2014. The snail density in the whole province fluctuated from 2004 to 2008, and the overall snail density in the whole province showed a downward trend since 2011. Since 2011, the average snail density has fluctuated and hovered. The infection rate of snail decreased rapidly in 2012, and no infectious snail was found in 2013 and 2014 for two consecutive years. The infection rate of schistosomiasis in the population decreased year by year from 2004 to 2014. The number of acute schistosomiasis infections in each year after 2006 was below 50, and the cases were scattered. There was no acute schistosomiasis infection in the province in 2013 and 2014. the infection rate of schistosome in livestock decreased to 0.55% in 2004-2011 and decreased rapidly to 0.55% in 2012. The infection rate of livestock in 2014 was lower than that of schistosomiasis in the same period for the first time. After 2011, the process of schistosomiasis transmission control in the whole province accelerated. From 2012 to 2014, the number of counties (cities and districts) reached the standard of schistosomiasis transmission control was 4, 9, 14, and the number of townships (towns) was 33, 76 and 32, respectively. Conclusion the prevention and control of schistosomiasis in Anhui Province has achieved remarkable results, but the task of consolidating the achievements and even blocking the spread of schistosomiasis is still very arduous.
