| 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Arc View 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 epidemiologic status and geographical distribution of schistosomiasis in China. Methods Relevant detabases were set up after collection of data from two National Sampling Surveys on Schistosomiasis, in 1989 and 1995. Spatial analysis was undertaken after the database linked to the GIS software which was supported by Arc View 3.0a. Correlation analysis was performed to understand the relationship between rates of human infection and cattle infection. Results The epidemic areas of schistosomiasis with high risk are mainly distributed in the marshland along the Yangtze River and can be identified as five spatial distribution regions based on the Results of spatial analysis. Both epidemic areas and positive rates of stool examination in cattle and water buffalo are much wider and higher than that in humans. The positive correlation was seen between infection rate in human and in cattle from data of both sampling surveys. Conclusion The relevant strategy for schistosomiasis control in different spatial regions should be performed accordingly and the measures of control for cattle and water buffalo should be strengthened in the endemic areas. |
