【摘要】 目的了解全县钉螺和阳性钉螺分布现状,为急感防控、查灭螺工作及探索今后的防治策略和措施提供依据。方法于2015年开展全县螺情调查,同时收集2013~2014年螺情数据进行分析。结果枞阳县现有钉螺面积1 542.8hm2,分布于8个乡镇的28个行政村。全县有螺框出现率16.59%,钉螺平均密度为0.776只/0.11m2,未查到阳性钉螺。钉螺主要分布在江、洲、湖滩,呈片状分布,占总有螺面积98.56%;内陆环境有螺面积较少,钉螺呈点状分布于沟、塘及距居民点附近。2015年全县有螺面积继续下降,仍未查获感染性钉螺。结论枞阳县螺情呈下降趋势,防控成果进一步巩固。更多还原

【Abstract】 Objective To understand the current status and characteristics of the snail distribution in Zongyang County for following strategies in urgent control, prevention and survey of the schistosomasis.Methods Prevalence of snails were surveyed in 2015 throughout Zongyang County, and the data were collected and compared with those obtained from 2013 to 2014. Results The area prevalent with snails were 1542.8hm2 in 2015, located in 28 administrative villages of 8 towns. Snails were seen in 16.59% of the frames surveyed, and the average density of living snails was 0.776/0.11m2. None infected snails were found. Snails were mainly distributed in the marshland, bottomland and lake shore in strip fashion, which accounted for 95%of the total living snails area. Snails were less prevalent in inland areas, and scattered in the ditch, pond and settings near the residential areas. The areas with snails were decreased in 2015 across the county compared to the past two years, and no infected snails were detected. Conclusion The area with snail generally tends to decline in Zongyang County, however, the gain in prevention and control of snails should be consolidated in following tasks.更多还原
