Abstract: Objective To explore the reasons for the tardy descending trend of snail.Methods Data of snail screen and control in the schistosomiasis endemic areas through 2005 to 2011 were collected and analyzed.Results From 2009 to 2011,the percentage of the area with snails in those of all-killed snails or suspicious area was 16.00%,45.69% and 27.75% respectively;the percentage of the area with snails in the last year in those of all-killed snails was 84.00%,54.31% and 72.25% respectively.From 2009 to 2011,there are 26 administrative villages were detected the snails,15 of them are administrative villages at plateau canyon areas,with a percentage of 57.69%.From 2009 to 2011,the oncomelania distributed areas of plateau canyon areas in oncomelania distributed areas of the county ranged 55.18% to 60.77%;and the percentage of frames with living snail and average concentration of living snails in plateau canyon areas was higher than that of plateaus region areas.Conclusion The descending speed of oncomelania from 2009 to 2011 is tardy.Comprehensive measures such as molluscicide as well as environment reform should be taken to thoroughly alter the breeding surroundings,and thus to substantially compress the snail areas.
