2006年云南省血吸虫病疫情监测结果分析

The results analysis of surveillance of schistosomiasis in Yunnan Province in 2006

目的了解2006年血吸虫病监测点的疫情状况,为全省防治工作提供参考。方法根据《全国血吸虫病监测方案》,在云南4个国家级监测点开展血吸虫病疫情监测。结果全省4个监测点人群感染率为1.92%,黄牛与水牛的感染率分别为3.65%和6.59%,有螺面积99.44hm2,钉螺密度为0.37只/0.11m2,钉螺感染率为0.08%。结论总体疫情程度下降,但牛的感染率依然较高,个别监测点未能有效控制螺情,仍应加强家畜和钉螺的血吸虫病防控工作。

Objective To understand the schistosomiasis endemic situation of surveillance sites, in order to offer the scientific evidence for schistosomiasis control in Yunnan province. Methods To carry, out the surveillance in four national sites in Yunnan province and analyze the results according to the National Scheme of Schistosomiasis Surveillance. Results In four surveillance sites in Yunnan province, the average infection rate of the residents was 1.92%, and the infection rate of cattle and water buffaloes was 3.65% and 6.59%. The snail area was 99.44 hm^2,and the average density of the snail was 0.37 snail/0.11m^2,the infection rate of snail was 0.08%. Conclusion The endemic situation of schistosomiasis fell obviously after control measures were carried out, but the domestic animals played an important role in the transmission of schistosomiasis, and the snails were not well controlled in some sites. So the surveillance and control to cattle and snail should be continuously strengthened.
