Abstract: Objective Describe and analyze epidemiological characteristics of COVID-19 in Guangxi to provide evidence for prevention and control. Methods The infarmation of 252 cases reported in Guangxi were collected through the China Disease Prevention and Control Information System from January 22 to March 23,2020. Descriptive epidemiological methods were used to retrospectively analyze the spatial,temporal and population distributions, history of exposure, and clustered outbreak characteristics of the cases. Results The incidence was mainly concentrated in people aged 20 to 59 years （74.2%）. The clinical severity was dominated by the common type （75.0%）. The peak incidence was from January 19 to February 1 （67.1%）. The epidemic situation affected 57 counties in 13 cities, mainly imported cases （61.1%）. A total of 50 clustered outbreaks were reported, mainly family aggregation （88.0%）, and local cases were mainly family aggregation infections （accounting for 74.5% of the total number of local cases）. Conclusion COVID-19 epidemic in Guangxi is dominated by imported cases in the early stage and local cases in the later stage. The family aggregation is obvious. The early prevention and control measures in Guangxi have showed effective results and the epidemic has shifted to a low-risk distribution state. With the increase in the number of personnel returning to work, production and transportation, and the global spread of the epidemic, it is necessary to strengthen the prevention and control of special institutions and communities, as well as the control of the importation of personnel in high-risk areas.
