2008-2011年浙江省嘉兴市水网型地区血吸虫病监测点监测疫情分析

Surveillance of schistosomiasis in rivers and lakes area in Jiaxing, Zhejiang,2008-2011

  • 摘要: 目的 了解浙江省嘉兴市秀洲区省级血吸虫病监测点疫情动态和流行现状,为制定浙江省水网型地区血吸虫病防治对策和评价防治效果提供参考依据。 方法 根据《浙江省血吸虫病监测点监测方案》,每年对浙江省嘉兴市秀洲区螺情、常住居民、流动人员和耕牛病情等情况进行监测,纵向观察、分析水网型地区疫情变化趋势。 结果 浙江省嘉兴市秀洲区2008-2011年累计查螺面积261 050 m2,2009年发现复现螺点,活螺密度0.44只/框,活螺率100%,有螺框出现率为8.82%,未发现感染性钉螺。本地居民血吸虫病间接血凝试验监测平均阳性率为2.27%。各年间差异有统计学意义(2=34.079,P0.005)。全区开展输入性传染源监测,2009年查出输入性急性血吸虫病患者1例。 结论 监测区2008-2011年间有钉螺复现,外来输入传染源存在,警惕局部流行的危险存在。应重点做好螺情和外来疫区流动人员的监测工作,巩固已经取得的血防成果。

     

    Abstract: Objective To understand the epidemic pattern of schistosomiasis in Xiuzhou district in Jiaxing, Zhejiang province and provide evidence for the development of prevention and control strategy of schistosomiasis and effect evaluation in rivers and lakes area in Zhejiang. Methods According to Zhejiang provincial schistosomiasis surveillance protocol, the surveillance of schistosomiasis was carried out in Xiuzhou from 2008 to 2011 to understand the snail distribution and information about local residents and floating population as well as sick cattle. Results Snail distribution was surveyed in an area of 261 050 ㎡. Remerging snail spots were found in 2009. The density of alive snails was 0.44/box, and alive snail rate was 100%. The boxes in which snails were found repeatedly accounted for 8.82% and no infected snail was found. The average positive rate of indirect hemagglutination (IHA) in local residents was 2.27%, the yearly differences had statistical significance (2=34.079, P0.005). One imported acute case of schistosomiasis was detected in 2009. Conclusion Snails were re-found and imported infection source existed in Xiuzhou during 2008-2011. It is critical to strengthen the surveillance of snail distribution and schistosomiasis in floating population to consolidate the gain already made in schistosomiasis prevention and control.
