摘　　要：目的探讨斯氏并殖吸虫病阻断流行的因素。方法现场观察斯氏并殖吸虫疫源地生态环境变化,同时调查动物宿主孳生和感染情况及影响因素。结果疫源地生态环境的改变、特别是人类的行为对肺吸虫中间宿主的孳生和感染有较大的影响。社区斯氏并殖吸虫孳生地第二中间宿主锯齿华溪蟹(Sinopotamon denticulatum)、光泽华溪蟹(S.davidi),感染调查阳性率从1985年～1995年的15.44%(67/434)下降到1996年-2007年的3.80%(11/290)。人群并殖吸虫感染率为9.18%(19/207),多为隐性感染。结论由于人类的行为造成中间宿主生态环境的改变和肺吸虫病防治引导等因素,导致十堰城区并殖吸虫自然疫源地的消失,从而阻断了并殖吸虫病的流行。但十堰地区作为斯氏肺吸虫病的流行区,应继续加强当地肺吸虫病的预防和控制工作。Objective To analyze the factor blecking the prevalence of pagumogonimusis in Shiyan City,Hubei Province.Methods The infectous focus of Paragonimus skrjabini and the intermediate host of Paragonimus skrjabini,the factors associated with Paragonimus skrjabini infection including cahnges of environment,vegetation and huamn behavior of human were surveyed.Results The influence of natural factor,human behavior on Sinopotamon denticulatum and S.davidi,the intermediate hosts of Paragonimus skrjabini was fundamentally imporant.The infection rates of Paragonimus skrjabini in the intermediate hosts were reduced from 15.44%（67/434）in 1985～1995 to 3.80%（11/290）in 1996～2007.Conclusion The disappearance of natural focus in Shinayan city is associated with the changes of environemnt,human behavior influencing the survival of intermediate houst and the prevalence of paragonimiasis and the prevention and control operation.But Shiyan is an endemic area of pagumogonimus,control activities should be continuously carried out for consolidating the results and eliminating paragonimiasis.
