2006年云南省血吸虫病疫情监测结果分析

Analysis of surveillance results of schistosomiasis in Yunnan Province,2006

目的掌握云南省国家级血吸虫病疫情监测点2006年疫情状况,为全省防治工作提供科学依据。方法根据《全国血吸虫病疫情监测方案》,在4个国家级血吸虫病疫情监测点进行调查,并分析其结果。结果全省4个监测点人群感染率为1.92%,黄牛及水牛感染率分别为3.65%和6.59%,有螺面积99.44hm2,钉螺密度为0.37只/0.1m2,钉螺感染率为0.08%,云南省居民血吸虫病有高感染率、低感染度的流行特点。结论云南省血吸虫病疫情下降明显,家畜传染源在血吸虫病传播中占有特殊地位,部分监测点螺情未得到有效控制,应进一步加强家畜血吸虫病的防治和查灭螺工作。

Objective To understand the schistosomiasis endemic situation of surveillance sites in order to offer the scientific evidence for schistosomiasis control in Yunnan Province. Methods According to the protocol of national surveillance of schistosomiasis, four national sites in Yunnan Province were surveyed and the results were analyzed. Results In the four surveillance sites in Yunnan Province, the average infection rate of schistosomiasis of residents was 1.92%, and the infection rates of cattle and water buffaloes were 3.65% and 6.59% respectively. The snail area was 99.44 hm^2, and the average density of the snails was 0.37 snail/0.1 m^2, and the snail infection rate was 0.08%. There was the feature of higher infection rate and lower infection intensity in residents in Yunnan. Conclusions The endemic situation of schistosomiasis falls obviously after the control. However, the domestic animals still play an important role in the transmission of schistosomiasis, and the snails are not well controlled in some sites. So the surveillance and control to cattle and the snail should be continuously strengthened.
