Abstract：Objective To analyze the epidemic characteristics of coronavirus disease 2019 (COVID-19) in Shaoyang city so as to provide a scientific basis for its prevention and control. Methods Demographic, epidemiological and clinical data related to COVID-19 cases in Shaoyang city as of February 11, 2020 were collected. A database was established, and SPSS 18.0 software was used for descriptive statistical analysis. Results A total of 94 confirmed cases were reported, including 21 familial clusters, with two peaks of imported cases in Wuhan (or Hubei) and local secondary cases. The main distribution regions of the cases were Shaodong city, Xinshao county and Dongkou county (accounting for 69.15%). The crude incidence rate in the whole population was 1.28/100,000, and the rate in Shaodong city was the highest (4.06/100,000). The age of onset ranged from 8 to 84 years old, mainly in the age group of 20-59 years (accounting for 79.8%) as well as in those who hada history of travelling or residencein Wuhan (or Hubei) and returned home from work (accounting for 69.15%). The proportion of severe cases (or critical illness cases) in the elderly confirmed cases aged 60 years and above was 66.7% (10/15), which was higher than that in the age group under 60 years (χ2=31.150, P<0.001). Conclusions The COVID-19 epidemic situation in Shaoyang city is serious and prone to family aggregation epidemic, and the elderly are apt to serious illness. COVID-19 prevention and control should be strengthened, especially the targeted protection for the elderly aged above 60 years.
