目的了解常州市2008~2012年螺情变化情况,为控制钉螺提供科学依据。方法收集常州市2008~2012年的螺情监测资料并进行统计分析。结果常州市2008~2012年累计有螺面积43.99万m2,其中新发现有螺面积6.94万m2,占15.78%。全市共查到有螺环境58个,其中江滩、湖滩、内陆、山丘类型的有螺面积分别为13.60万m2,7.30万m2,2.70万m2,20.39万m2,所占比例分别为30.92%,16.59%,6.14%,46.35%。复现有螺环境的原因主要是灭螺效果差和外来输入。5年累计药物灭螺面积155.09万m2,累计历史有螺环境改造面积87.40万m2。结论常州市近5年螺情有波动,血吸虫病传播阻断后仍需加强螺情监测。
Objective To understand the changes of snails in Changzhou from 2008 to 2012 and provide a scientific basis for the control of snails. Methods The data of snail surveillance from 2008 to 2012 in Changzhou City were collected and analyzed statistically. Results The total area of Changzhou from 2011 to 2012 was 439,900 m2 with a newly found area of 69,400 m2, accounting for 15.78%. A total of 58 snail environments were found in the city, of which the snail areas of riverside, lakeshore, inland and hillside types were 136,000 m2, 73,000 m2, 270,000 m2 and 203,900 m2 respectively, accounting for 30.92%, 16.59%, 6.14%, 46.35%. Recurrence of spirulina environment mainly because of the poor effect of snail and foreign input. 5 years cumulative drug snail area of 155900 m2, the cumulative history of a spiral environment reconstruction area of 874000 m2. Conclusion The spirochetes in Changzhou City fluctuated in the past 5 years. Survival of schistosomiasis still needs to be strengthened after the transmission of schistosomiasis is blocked.
