目的 了解全国血吸虫病流行情况和空间分布。方法 收集全国两次血吸虫病抽样调查资料 ,建立相关数据库 ,在ArcView 3 .0a软件的支持下 ,与建立的数据库相联 ,并进行空间分析。对抽样调查的人群和耕牛感染率作相关分析。结果 目前我国血吸虫病分布的高危地区主要分布于沿长江的江湖洲滩 ,可将全国血吸虫病病区划分为 5个主要空间分布区域。发现耕牛血吸虫病的空间分布范围及粪检阳性率较人群血吸虫病的严重。两次抽样调查的人群感染率和耕牛感染率呈正相关关系。结论 不同区域内的血吸虫病防治应采取相应的对策 ,沿长江重流行区的重点应加强耕牛血吸虫病防治措施
Objective To understand the prevalence and spatial distribution of schistosomiasis in China. Methods The data of two national schistosomiasis sampling surveys were collected and the relevant databases were established. The software was linked with the established database with ArcView 3 .0a software and analyzed. The sample survey of the population and cattle infection rate for the correlation analysis. Results At present, the high-risk areas of schistosomiasis distribution in China are mainly distributed in the rivers and lakes of the Yangtze River along the Yangtze River. Schistosomiasis wards can be divided into five major spatial distribution areas. Found that the spatial distribution of cattle schistosomiasis and the positive rate of fecal examination than the crowd of schistosomiasis serious. The two-sample survey of the population infection rate and cattle prevalence was positively correlated. Conclusions Corresponding countermeasures should be taken in the prevention and treatment of schistosomiasis in different regions. The prevention and control measures of cattle schistosomiasis should be strengthened along the focus of the heavy traffic areas in the Yangtze River
