2010-2014年四川省邛崃市血吸虫病疫情监测分析

Monitoring and Analysis of Epidemic Status of Schistosomiasis in Qionglai City in Sichuan Province,2010-2014

目的及时掌握四川省邛崃市血吸虫病流行现状,疫情动态变化,为制定血吸虫病防治规划和决策提供科学依据。方法根据《全国血吸虫病监测方案》要求,开展了2010-2014年血吸虫病监测工作。结果邛崃市榆树村监测点钉螺面积从2010年48 800 m2,下降到2014年25 050 m2,下降率48.66%,活螺密度从0.66只/0.11 m2下降到2014年的0.42只/0.11 m2,下降率36.36%,无阳性钉螺。间接血球凝集试验阳性率从2010年8.01%,下降到2014年3.93%,五年来居民粪检阳性率均为0%。结论邛崃市血吸虫病已控制在较低水平,应继续加强"以传染源控制"为主的血吸虫病综合防治策略,加强人群和家畜血吸虫病情监测,进一步减少耕牛,加大钉螺控制力度。
