目的分析云南省血吸虫病流行现状,为制订下一步防治策略提供依据。方法收集2014年云南省血吸虫病疫情资料,分类统计传播控制和传播阻断地区血吸虫病流行情况。结果目前云南省达到传播控制和阻断标准的血吸虫病流行县分别为7个和11个,其中传播阻断地区5年以上查不到螺的地区有5个。传播控制地区流行村数、人口数、耕牛数和有螺面积,分别占全省流行地区的80.94%、83.72%、79.32%和82.00%,血吸虫病传染源尚未彻底消除。结论云南省血吸虫病传播控制地区应继续清除残留的传染源,防止疫情回升;传播阻断地区应防止传染源输入,进一步巩固防治成果。
Objective To analyze the prevalence of schistosomiasis in Yunnan Province and provide the basis for further prevention and control strategies. Methods The epidemic data of schistosomiasis in Yunnan Province were collected in 2014, and the prevalence of schistosomiasis in the areas controlled by transmission and dissemination was categorized. Results At present, endemic counties of schistosomiasis in Yunnan Province, which have reached the standard of transmission control and blockage, are 7 and 11, respectively, of which 5 are found in areas with no block of transmission over five years. The number of epidemic villages, population, number of cattle breeds and snail areas in the areas under the control of dissemination accounted for 80.94%, 83.72%, 79.32% and 82.00% of the endemic areas in the province respectively, and the source of infection of schistosomiasis has not been completely eliminated. Conclusion In Yunnan, the area of transmission control of schistosomiasis should continue to clear the source of residual infection and prevent the epidemic from rising. In areas with transmission interruption, the sources of infection should be prevented to further consolidate the prevention and treatment results.
