目的了解大理州2009年血吸虫病疫情现状,为评价防治效果和做好下一步的防治工作提供参考。方法制定《大理州血吸虫病监测方案》,按要求开展疫情监测工作。结果全州共确定7个疫情监测点,分布于5个血吸虫病重点流行县(市),监测点的居民感染率0.47%;家畜平均感染率0.40%;钉螺面积119 574 m2,活螺平均密度0.280 2只/框(每框=0.11 m2),未发现感染性钉螺。结论大理州血吸虫病疫情总体上已处于较低水平,部分高原峡谷型流行地区的疫情还不太稳定,今后应重点加强这类地区的防治工作。
Objective To understand the status quo of schistosomiasis in Dali Prefecture in 2009 and provide reference for evaluating the control effect and preventing and curing the next step. Methods Development of “Dali Prefecture schistosomiasis monitoring program”, carried out as required epidemiological surveillance. Results A total of 7 epidemic surveillance spots were identified in the whole state. Among the 5 endemic counties (cities) endemic to schistosomiasis, the infection rate at the monitoring sites was 0.47%; the average infection rate of domestic animals was 0.40%; the snail area was 119 574 m2; 0.280 2 per box (per box = 0.11 m2), no infectious snails found. Conclusion The epidemic situation of schistosomiasis in Dali Prefecture is generally at a low level. The epidemic in some plateau-canyon-endemic areas is not yet stable. Therefore, the prevention and treatment of such areas should be strengthened in the future.
