目的 掌握湖南省洞庭湖流域武警部队血吸虫病疫情，为制定有针对性的防治措施提供科学依据。方法 从武警部队血吸虫病流行病学调查数据库和湖南省血吸虫病疫情数据库中，按分层整群的原则，在洞庭湖流域贯穿的常德、益阳和岳阳市随机抽取20余个执勤点和相对应的流行区、村为调查点，收集部队官兵及地方人群血吸虫病血清学特异性抗体水平（IgG）、年龄特征、工作性质特征和文化程度等进行分析比较。结果 该地区武警部队官兵血吸虫病特异性抗体水平明显低于地方同龄人群（χ2=6.769，P＜0.05）；血吸虫感染与疫区生活时间长短、工作性质和文化程度等有关。结论 驻洞庭湖血吸虫病流行区武警部队官兵存在血吸虫感染的高危因素，提高官兵对血吸虫病的防治的依从性和主动性是目前控制疫区部队人员感染的主要措施。

Objective
To collect data on the status of schistosomiasis epidemic in Armed Police Forces in Dongting Lake Basin, Hunan Province, in order to establish the scientific basis for developing targeted prevention measures.  Methods Epidemiological investigation was conducted of schistosomiasis from the Armed Police database and the database of schistosomiasis in Hunan Province. Stratified groups in the Dongting Lake Basin, including Changde, Yiyang, Yueyang and 26 garrison points and related villages, were randomly chosen to gather information about specific serological schistosomiasis antibody levels (IgG), age, occupations and education levels. The data were analyzed and compared.  Results The region-specific schistosmiasis antibody level in Armed Police Forces was significantly lower than that in the local population (P＜005). Length of inhabitation in epidemic areas, occupations and the education level were related to the extent of schistosomiasis infection. Conclusions Schistosomiasis in the Armed Police Forces in the Dongting Lake is a risk factor of schistosome infection. Enhancing comprehensive management, strengthening health education, and encouraging troops’compliance and initiative are effective measures for control of epidemic.
