摘　　要：目的分析广西新型冠状病毒肺炎(COVID-19)疫情流行特征,为防控提供依据。方法采用描述性流行病学方法,通过中国疾病预防控制信息系统收集2020年1月22日至3月23日广西报告的252例境内COVID-19确诊病例资料,对病例的三间分布、暴露史和聚集性疫情特征进行回顾性分析。结果发病主要集中在20~59岁人群(占74.2%),临床严重程度以普通型为主(占75.0%),发病高峰在1月19日至2月1日(占67.1%)。疫情波及13个市57个县(市、区),以输入病例为主(占61.1%)。累计报告50起聚集性疫情,以家庭聚集性为主(占88.0%),本地病例主要为家庭聚集感染(占本地总病例数的74.5%)。结论广西COVID-19疫情前期以输入病例为主,后期以本地病例为主,家庭聚集性明显,广西前期防控措施成效显现。但随着复工复产复运复学人员流动增加,以及疫情全球传播,应加强特殊机构和社区防控以及高危地区输入人员管控。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 to59 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.
