Abstract：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 0.242,0/0.1m2 in 2004 to 0.000,5/0.1m2 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.
