由急性呼吸道综合征冠状病毒2型（SARS-CoV-2）引起的冠状病毒病（COVID-19）是一项全球性挑战，影响着包括阿曼苏丹国（阿曼）在内的210多个国家的数百万人。我们采用时空分析探讨2020年4月29日至6月30日期间COVID-19传播的空间模式。我们的评估是使用五个地理空间技术在地理信息系统（GIS）的背景下，包括加权平均中心（WMC），标准偏差椭圆，莫兰的我自相关系数，Getis-Ord一般G高/低聚类，和Getis-Ord统计。Moran's I-/G-统计证明，数据集中的COVID-19病例（病例数）在整个研究期间都是聚集的。Moran's I和Z评分高于2.25阈值（置信水平高于95%），范围从2020年4月29日的2274例到2020年6月30日的40，070例。结果表明，感染率各不相同，不同地区之间存在很大的空间差异。马斯喀特省的穆特拉、阿斯塞卜、鲍舍等部分省份疫情较为严重，Z评分高于5分，目前传播仍呈现上升趋势。这项研究表明，COVID-19病例的方向性模式已从东北向西北和西南移动，总的受影响区域随着时间的推移而增加。此外，结果表明，在人口最稠密的地区，COVID-19感染率较高。本文的研究结果提供了一个坚实的基础，为未来的研究，更详细地调查最坚决的热点，并可能帮助决策者确定有针对性的地区，以减轻计划。在线版本包含补充材料，可通过10.1007/s41748-020-00194-2获得。
Coronavirus disease (COVID-19), caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a worldwide challenge effecting millions of people in more than 210 countries, including the Sultanate of Oman (Oman). Spatiotemporal analysis was adopted to explore the spatial patterns of the spread of COVID-19 during the period from 29th April to 30th June 2020. Our assessment was made using five geospatial techniques within a Geographical Information System (GIS) context, including a weighted mean centre (WMC), standard deviational ellipses, Moran’s I autocorrelation coefficient, Getis-Ord General-G high/low clustering, and Getis-Ord statistic. The Moran’s I-/G- statistics proved that COVID-19 cases in datasets (numbers of cases) were clustered throughout the study period. The Moran’s I and Z scores were above the 2.25 threshold (a confidence level above 95%), ranging from 2274 cases on 29th April to 40,070 cases on 30th June 2020. The results of showed varying rates of infections, with a large spatial variability between the different wilayats (district). The epidemic situation in some wilayats, such as Mutrah, As-Seeb, and Bowsher in the Muscat Governorate, was more severe, with Z score higher than 5, and the current transmission still presents an increasing trend. This study indicated that the directional pattern of COVID-19 cases has moved from northeast to northwest and southwest, with the total impacted region increasing over time. Also, the results indicate that the rate of COVID-19 infections is higher in the most populated areas. The findings of this paper provide a solid basis for future study by investigating the most resolute hotspots in more detail and may help decision-makers identify targeted zones for alleviation plans.
