传染病已经造成了一些最可怕的瘟疫，并极大地危害了人类健康。然而，尽管人们定性地认识到传染病的发生和扩散与环境有关，但许多疾病的定量关系尚不清楚。寨卡病毒(ZIKV)是一种蚊媒病毒，构成致命威胁，已在世界各地爆炸性传播，影响人类健康。本研究旨在从地理学的角度，运用探索性空间数据分析(ESDA)模型，了解ZIKV的全球热点以及ZIKV与环境因素之间的空间异质性关系。利用地理加权回归(GWR)模型分析了大陆尺度上主要环境因子对寨卡病毒传播的影响。结果表明，寨卡病毒传播具有明显的地区和季节异质性。人口密度、人均GDP和景观破碎化是影响ZKV传播的主要环境因素，说明社会因素对ZKV传播的影响大于自然因素。随着SARS-CoV-2在全球范围内的传播，本研究可为抗击SARS-CoV-2疫情提供方法学参考。
Infectious diseases have caused some of the most feared plagues and greatly harmed human health. However, despite the qualitative understanding that the occurrence and diffusion of infectious disease is related to the environment, the quantitative relations are unknown for many diseases. Zika virus (ZIKV) is a mosquito-borne virus that poses a fatal threat and has spread explosively throughout the world, impacting human health. From a geographical perspective, this study aims to understand the global hotspots of ZIKV as well as the spatially heterogeneous relationship between ZIKV and environmental factors using exploratory special data analysis (ESDA) model. A geographically weighted regression (GWR) model was used to analyze the influence of the dominant environmental factors on the spread of ZIKV at the continental scale. The results indicated that ZIKV transmission had obvious regional and seasonal heterogeneity. Population density, GDP per capita, and landscape fragmentation were the dominant environmental factors affecting the spread of ZIKV, which indicates that social factors had a greater influence than natural factors on the spread of it. As SARS-CoV-2 is spreading globally, this study can provide methodological reference for fighting against the pandemic.
