Abstract:

Objective To investigate the prevalence of schistosomiasis in Armed Police Forces in marshland and lake regions so as to provide the evidence for policy?making of the disease control. Methods The different types of duty were selected by the stratified cluster random sampling method in endemic areas of marshland and lake regions，and the snail survey was conducted， and the infectious status and epidemic factors of officers and soldiers who served more than 2 years were investigated. Results The geographical features included the embankment type，island type and islet type，and the serological positive rates were 1.88%，4.73% and 3.89% in the 3 types of endemic areas respectively and he total positive rate was 3.10%，that was lower than the national population level in 2009. The infection risk factors included fighting flood，and the contact with infested water in daily life and production. Conclusions We should strengthen the surveillance and control of schistosomiasis in this particular group of officers and soldiers， especially in their implementation of fighting flood and other tasks.

摘要：

目的 掌握驻湖沼型血吸虫病流行区武警部队官兵血吸虫病流行状况， 为制定和优化适合武警部队特点的血吸虫病防治对策和措施提供科学依据。 方法 采用分层整群随机抽样法选择驻湖沼型血吸虫病流行区不同类型流行县的武警部队执勤点， 开展螺情调查； 同时， 对服役＞2年的官兵进行血吸虫感染情况调查和流行因素调查。 结果 武警部队驻地调查点地理特征分为垸内亚型、 洲岛亚型和洲滩亚型， 官兵血吸虫血清学检查阳性率分别为1.88％、 4.73％、 3.89％， 总阳性率为3.10%， 低于2009年全国人群水平。感染原因与官兵参加疫区抗洪抢险及日常执勤、 生活生产过程中经常性、 不经意接触疫水有关。 结论 应加强对驻疫区武警部队官兵这一特殊人群的血吸虫病疫情的监测和防治， 尤其是对执行抗洪抢险等任务和日常执勤、 生产生活中的行为干预。
