摘要
目的评价长沙市实施"环改灭螺为主,药物灭螺为辅"的综合控螺策略对湖沼型垸内亚型钉螺活螺平均密度的影响。方法收集长沙市2004-2015年血吸虫防治报表数据,采用SPSS 18.0对长沙市实施综合控螺策略后2004-2015年钉螺活螺平均密度进行统计分析。结果长沙地区钉螺活螺平均密度从2004年的0.242 0只/0.1 m2下降到2015年的0.000 5只/0.1 m2。该策略实施后1年活螺平均密度下降率平均为77.355%(95%CI:64.713%~90.046%),3年活螺平均密度下降率平均为98.327%(95%CI:95.221%~99.953%),5年活螺平均密度下降率平均为94.862%(95%CI:89.290%~99.345%),10年除岳麓区外,各区县基本消灭了钉螺,活螺平均密度下降率达到了99.996%(95%CI:99.987%,100.000%)。结论综合控螺策略可在10年内将湖沼型垸内亚型钉螺活螺密度控制在较低水平,对巩固取得的血防成果具有重要意义。
Objective To evaluate the effect of implementing comprehensive strategy of snail control based on environmental reform-oriented and molluscicide-subsidiary measures on the average density of living Oncomelania snail in inner embankment of marshland and lake regions in Changsha City. Methods The data regarding schistosomiasis control reports in Changsha City during 2004-2015 were collected,and SPSS 18.0 software was used to statistically analyze the average density of living Oncomelania snail after comprehensive snail control strategy was implemented in Changsha City in 2004-2015. Results The average density of living Oncomelania snail in Changsha City was declined from 0.242,0/0.1 m2 in 2004 to 0.000,5/0.1 m2 in 2015. After the comprehensive strategy was implemented,the average decline rates of 1-year,3-year and 5-year average density of living Oncomelania snail were 77.355%（ 95%CI： 64.713%-90.046%）,98.327%（ 95%CI： 95.221%-99.953%） and 94.862%（ 95%CI：89.290%-99.345%） respectively. No infected snails were found in districts or counties except Yuelu District after the comprehensive strategy was implemented for 10 years,and the decline rate of average density of living Oncomelania snail reached 99.996%（ 95%CI： 99.987%-100.000%）. Conclusions The density of living Oncomelania snail can be kept at a low level in inner embankment of marshland and lake regions in Changsha City after the comprehensive snail control strategy is implemented for 10 years,and it is of great value to consolidate the achievements in schistosomiasis control.
