目的利用地面和空间数据分析血吸虫感染与环境空间的关系。方法选择鄱阳湖区重疫区村进行居民血吸虫感染状况及行为学调查,利用GPS采集相关的空间数据,通过ArcGIS和SAS软件进行统计分析。结果居民血吸虫平均感染率为18.08%,其中渔(船)民最高,为41.18%,农民和学生的血吸虫感染率>10%;居民居住的地理位置与血吸虫感染密切相关。结论湖区血吸虫病高危人群为离沿湖居住较近的居民,其是湖区血吸虫病防治的重点人群。
Objective To analyze the relationship between schistosoma infection and environmental space using surface and spatial data. Methods The epidemic situation and behavioral investigation of schistosomiasis in the infested area of Poyang Lake area were investigated. Relevant spatial data were collected by GPS and analyzed by ArcGIS and SAS software. Results The average infection rate of resident schistosomiasis was 18.08%, of which the highest was fishery (boat), 41.18%, and the infection rate of schistosomiasis was> 10% for peasants and students. The geographical location of residents was closely related to schistosomiasis infection. Conclusions The high risk population of schistosomiasis in the lake is the resident who lives close to the lake, which is the key population for the prevention and control of schistosomiasis in the lake area.
