Geographic information systems (GIS) can be used to map the geographical distribution of the prevalence of disease, trends in disease transmission, and to spatially model environmental aspects of disease occurrence. The aim of this study is to discuss a GIS application created to produce mapping and cluster modeling of three diseases in Jeddah, Saudi Arabia: diabetes, asthma, and hypertension. Data about these diseases were obtained from health centers’ registered patient records. These data were spatially evaluated using several spatial–statistical analytical models, including kernel and hotspot models. These models were created to explore and display the disparate patterns of the selected diseases and to illustrate areas of high concentration, and may be invaluable in understanding local patterns of diseases and their geographical associations.

使用GIS在沙特阿拉伯吉达进行疾病制图和聚类

地理信息系统（GIS）可用于绘制疾病流行程度的地理分布图，疾病传播趋势以及对疾病发生的环境方面进行空间建模。这项研究的目的是讨论一个GIS应用程序，该应用程序用于对沙特阿拉伯吉达的三种疾病（糖尿病，哮喘和高血压）进行制图和聚类建模。有关这些疾病的数据来自卫生中心的注册患者记录。使用几个空间统计分析模型，包括核模型和热点模型，对这些数据进行了空间评估。这些模型的创建是为了探索和展示所选疾病的不同模式并说明高度集中的地区，在理解疾病的本地模式及其地理关联方面可能具有不可估量的价值。
