2005-2010年镇江市国家级血吸虫病监测点疫情监测

目的 掌握镇江市国家级血吸虫病监测点疫情变化。方法 按《全国血吸虫病监测方案》要求，选择镇江市扬中市石城村和丹徒区三洲村为国家级血吸虫病监测点，于2005-2010年开展血吸虫病病情和螺情监测，并对监测结果进行分析。结果 2010年石城村和三洲村监测点活螺平均密度、感染性钉螺密度、感染性钉螺面积、居民血检阳性率分别较2005年下降了98.4%、0、0、71.8%和70.4%、100%、100%、81.5%，2个监测点连续6年均未发现急性血吸虫感染病例。结论 镇江市国家级血吸虫病监测点人畜病情得到了有效控制，但钉螺面积变化不大，下一步应加强江滩有螺环境综合治理。

Surveillance of schistosomiasis in national surveillance sites of Zhenjiang City, 2005-2010

Objective To master the changes of schistosomiasis epidemic situation in national surveillance sites of Zhenjiang City， Jiangsu Province.

Results In 2010， in the Shicheng Village， the reduction rates of mean living snail density， infected snail density， area with infected snails， and positive blood tests in residents were 98.4%， 0， 0， 71.8% respectively， and in the Sanzhou Village， the reduction rates were 70.4%， 100%， 100% and 81.5%, respectively compared with those in 2005. No acute infections were found in the 2 villages during the period of 6 consecutive years. Conclusion In the national surveillance sites of Zhenjiang City， the schistosomiasis morbidity has been effectively controlled. However， the areas with snails change little.
