Opisthorchiasis, caused by Opisthorchis viverrini, is of considerable public health importance in Southeast Asia, particularly in Lao PDR and Thailand.
This study aims to analyze the risk areas for liver flukes in Surin province, Thailand using Geographic Information Systems (GIS).
The 5 main factors (131 variables) were: (1) personal data (2) knowledge, attitude and practice, (3) health service unit, (4) environmental data, and (5) climate data. The relationship between these mainfactors and liver fluke infection was analyzed using multiple regression analysis. Potential surface analysis (PSA) with geographic information systems (GIS) was performed to create maps displaying areas at risk for liver fluke infection in Surin province.
The population density (148-169 pop/km2; X73), human attitude (< 50%; X111), and land use (wetland; X64), were statistically significant with liver fluke infection by a percentage of 88.60% (Adjusted R2 = 0.886). The heavy risk areas covered 221.39 km2 and including 8 districts; Si Narong, Sangkha, Phnom Dong Rak, Mueang Surin, Non Narai, Samrong Thap, Chumphon Buri and Rattanaburi.
Present study identifies the increased risk areas for liver flukes in Surin Province and may be useful for future planning of prevention and control.
由湄公河肝吸虫引起的华支睾吸虫病在东南亚具有相当重要的公共卫生意义，尤其是在老挝人民民主共和国和泰国。
本研究旨在利用地理信息系统（GIS）分析泰国素林府肝吸虫的风险区域。
5个主要因素（131个变量）为：（1）个人数据；（2）知识、态度和行为；（3）卫生服务单位；（4）环境数据；（5）气候数据。使用多元回归分析这些主要因素与肝吸虫感染之间的关系。利用地理信息系统（GIS）进行潜在表面分析（PSA），以绘制显示素林府肝吸虫感染风险区域的地图。
人口密度（148 - 169人/平方公里；X73）、人类态度（< 50%；X111）和土地利用（湿地；X64）与肝吸虫感染具有统计学意义，占比88.60%（调整后R2 = 0.886）。高风险区域面积为221.39平方公里，包括8个区：西纳隆、桑卡、波东腊、素林市、诺纳莱、三龙塔、春蓬武里和拉塔纳武里。
本研究确定了素林府肝吸虫感染风险增加的区域，可能对未来的预防和控制规划有用。
