The agglomeration level of cases and incidences increased first and then remained high. The COVID-19 cases and high-incidence areas were mainly distributed in the middle, north, and northeast of Hunan, in regions in proximity to Wuhan 4) the epidemic was distributed with spatial aggregation. The epidemic occurred 'early in prefecture-level cities and frequently in urban areas' 3) the extent of the epidemic has distance attenuation. The confirmed COVID-19 cases were concentrated near major railway lines, which were also high-incidence areas. The epidemic in Hunan Province can be divided into four basic stages: the diffusion period, peak period, decay period, and the stagnant period.The first COVID-19 confirmed case of 84.47% affected counties was imported from Wuhan 2) The epidemic spread as a result of transportation convenience. The results show that: 1) The epidemic evolved with temporal phasing. Based on the COVID-19 confirmed cases and incidence, this article explored both the temporal and spatial distribution pattern of COVID-19 in Hunan Province and its influencing variables between January 21 and Februby using ArcGIS 10.3 and GeoDetector. At present, SARS-CoV-2 is still prevalent worldwide, and it is of great practical significance to strengthen the study on the COVID-19 epidemic. The COVID-19 epidemic spread globally at the start of 2020, resulting in a wide range of diffusion of infectious diseases.
