Abstract：Objective To investigate the epidemic characteristics of coronavirus disease 2019 (COVID-19) in Changsha city, and to provide a basis for prevention and control of the epidemic. Methods Descriptive epidemiological methods were used to analyze the epidemic characteristics of COVID-19 in Changsha city from January 1, 2020 to March 6, 2020. Results A total of 242 confirmed COVID-19 cases were reported in Changsha city between January 1, 2020 and March 6, 2020, with a severe case rate of 15.70%. The daily number of the newly reported confirmed cases showed a downward trend since February 3. The length of hospital stay of 209 discharged patients was 5-37 days, and the mean hospital stay was (16.91±7.32) days. 23.95% of the patients were in the age group of 30-50 years, and the severe case rate was found to be the highest in the group above the age of 50 years (26.26%, χ2=14.124, P=0.001). Most of the patients were housekeepers and the unemployed (16.53%) and retirees (15.70%). The main clinical manifestations were fever (65.70%), dry cough (41.74%) and fatigue (33.06%). Conclusions Although the number of COVID-19 cases shows a declining tendency, with the increase of personnel flow, prevention and control measures need to be strengthened to prevent the epidemic from rebounding.
