[目的]掌握2004～2008年西昌市血吸虫病疫情和流行趋势变化规律,为科学制定西昌市血吸虫病防治策略提供依据。[方法]2004～2008年每年开展人畜病情、螺情调查。[结果]2004～2008年人群血吸虫感染率分别为3.42%、2.69%、0.78%、0.62%和0.40%,家畜血吸虫感染率分别为0.086%、0.086%、0.052%、0.050%和0.047%,钉螺面积和钉螺密度逐年下降,感染率分别为0.0064%、0.0012%、0.0011%、0.00%和0.00%。[结论]在多年防治工作基础上采取措施加大力度的情况下,2008年西昌市人畜感染率和钉螺指标均达到血吸虫病传播控制标准。
[Objective] The research aimed to grasp the regularity of the change of epidemic situation and epidemic trend of schistosomiasis in Xichang from 2004 to 2008 and provide the basis for scientifically formulating the prevention and cure strategy of schistosomiasis in Xichang. [Methods] From 2004 to 2008, the investigation of human and animal disease and snail were carried out each year. [Results] The infection rates of schistosomiasis in population from 2004 to 2008 were 3.42%, 2.69%, 0.78%, 0.62% and 0.40%, respectively. The infection rates of schistosoma were 0.086%, 0.086%, 0.052%, 0.050% and 0.047% Area and snail density decreased year by year, the infection rates were 0.0064%, 0.0012%, 0.0011%, 0.00% and 0.00% respectively. [Conclusion] Under the condition of taking measures to increase the intensity on the basis of years of prevention and control work, the infection rate of snails and snails in Xichang City in 2008 both reached the control standard of schistosomiasis transmission.
