摘要： 目的 根据湖南省2011~2016年开展的3次垸内钉螺普查，对全省垸内钉螺的流行类型进行描述性分析，了解其变化趋势，为进一步降低垸内钉螺面积提供科学对策。 方法  收集2011年、2014年和2016年湖南省垸内钉螺普查的数据进行统计分析。 结果  湖南省垸内钉螺面积与环境处数在2011~2014年下降明显，2014~2016年下降趋缓；2016年全省垸内无新发和复发钉螺面积，3次普查均未查到感染性钉螺。全省现有垸内钉螺流行类型以湖沼型和山丘型为主。 结论  与2011年和2014年相比，2016年湖南省垸内钉螺面积继续呈下降趋势。全省应继续实施药物灭螺、沟渠硬化和国土平整等综合性防治措施，有效减少垸内钉螺面积，切断血吸虫病传播途径。

Abstract:

Objective  To understand the snail distribution trend in the inner embankment within Hunan province by descriptive analysis of the data based on the general survey of snail prevalence in the inner embankment from 2011 to 2016, in order to plan scientific measures to further reduce the snail ridden areas. Methods The data were collected from the  general survey of snail distribution in the inner embankment in Hunan province in 2011, 2014 and 2016, and statistically analyzed. Results  The areas with snails and environments with snails were fallen significantly from 2011 to 2014, yet the decrease was slow between 2014 and 2016. No areas of snail re-emergence or new emergent snail areas were found in the embankment in 2016 throughout the province, and no infected snails were found in three surveys. Snail prevalence in the inner embankment was associated with marshland and mountainous endemic areas. Conclusion  Snail habitats tend to decrease in 2016 compared to 2011 and 2014 in the inner embankment in Hunan province. Following measures and tasks should focus on continuous use of molluscicide, hardening conduits and land formation for effective reduction of snail ridden areas and complete cut-off the route of schistosome transmission.
