摘要
目的 了解2016—2021年池州市贵池区钉螺新发和复现情况,为制定防治方案提供依据。方法 依照《血吸虫病消除工作规范》和《钉螺调查技术规范》开展钉螺监测,收集2016—2021年贵池区现有钉螺环境、可疑钉螺孳生环境和历史钉螺环境信息,对贵池区新发和复现钉螺环境的面积、数量、活螺密度、活螺框出现率、地域特征等进行统计分析。结果 2016—2021年,贵池区新发钉螺环境面积分别为71.61、0、0.52、0、13.00、180.56 hm^(2),复现钉螺环境面积分别为82.27、12.67、8.48、5.12、28.50、291.59 hm^(2);新发钉螺环境数分别为12、0、2、0、2和24个,复现钉螺环境数分别为29、6、25、20、6和283个;新发钉螺环境平均活螺框出现率分别为18.41%、0、21.58%、0、17.58%、19.66%,复现钉螺环境活螺框出现率分别为8.46%、28.80%、17.15%、13.49%、8.55%、21.52%;新发钉螺环境活螺平均密度分别为0.42、0、2.62、0、0.97、0.91只/0.1 m^(2),复现钉螺环境活螺平均密度分别为0.70、1.01、1.10、1.65、0.68、1.43只/0.1 m^(2)。贵池区新发钉螺环境主要位于梅龙街道、江口街道和乌沙镇的长江滩地,牛头山镇和殷汇镇的秋浦河滩地;复现钉螺环境主要位于杏花村街道、殷汇镇的秋浦河滩地以及唐田镇升金湖滩地。新发钉螺环境所在水系主要为长江、秋浦河和九华河;钉螺复现环境所在水系主要位于秋浦河、白洋河和升金湖。结论 近年来贵池区每年均存在不同程度的钉螺扩散现象,对于出现新发或复现钉螺的重点地区,应及时采取有针对性的钉螺控制措施,防止钉螺扩散和血吸虫病蔓延。
Objective To understand the status of newly discovered and reemerged Oncomelania hupensis in Guichi District,Chizhou City from 2016 to 2021 for evidence to formulate the plans for prevention and control of schistosomiasis.Methods Snail monitoring was carried out in accordance with the Work Specifications for Schistosomiasis Elimination and Technical Specifications for Snail Investigation.Information on the existing snail environment,suspected snail breeding environment and historical snail environment in Guichi District was collected from 2016 to 2021,and the area,the number,live snail density,living frame occurrence rates of snails and regional characteristics of the newly and reemerging snail environments in Guichi District were analyzed.Results From 2016 to 2021,the environmental areas of newly emerging snails in Guichi District were 71.61,0,0.52,0,13.00 and 180.56 hm^(2),and the environmental areas of reemerging snails were 82.27,12.67,8.48,5.12,28.50 and 291.59 hm^(2),respectively.The number of newly emerging snail environments was 12,0,2,0,2 and 24,and the number of reemerging snail environments was 29,6,25,20,and283,respectively,for the 6 years.Average living frame occurrence rate was 18.41%,0,21.58%,0,17.58%and 19.66%for the newly emerging snails,and 8.46%,28.80%,17.15%,13.49%,8.55%and 21.52%,respectively for the reemerging snails.The average living density was 0.42,0,2.62,0,0.97 and 0.91 snails/0.1 m^(2)for the of newly emerging snail environments,and 0.70,1.01,1.10,1.65,0.68 and 1.43 snails/0.1 m^(2),respectively for the reemerging snail environments.The newly emerging snail environments in Guichi District were primarily in the beach at the Yangtze River in Meilong Community,Jiangkou Community and Wusha Town,Qiupu River beach in Niutoushan Town and Yinhui Town.The reemerging snail environments were mainly in Qiupu River beach in Xinghua Village Community and Yinhui Town and Shengjinhu beach in Tangtian Town.Yangtze River,Qiupu River and Jiuhua River were the main water systems where the newly emerged sn
