Abstract:
Objective To identify the epidemiological features of COVID-19 epidemic in Chenzhou City, Hunan province so as to provide scientific evidence for effective containment of the COVID-19 epidemic. Methods Descriptive epidemiological method was used to retrospectively characterize the confirmed COVID-19 cases and asymptomatic cases in Chenzhou City from January 23 through March 10, 2020. Results A total of 39 confirmed COVID-19 cases and 6 asymptomatic cases infection were documented in the city, with no death.We identified 8 clusters of COVID-19, which were all familial transmission.There was statistical difference between the sources of different types of epidemic (χ2=15.996, P < 0.001), in which all the local COVID-19 cases were the secondary cases in the clusters.As the epidemic expanded, the trend shifted from imported-case-centered to local-case-centered.The epidemic has covered 81.81% of the city area; in each area, the first COVID-19 cases were all imported. Conclusion The COVID-19 epidemic has been effectively controlled.At present, we focus on the quarantine in the entry and exit to prevent the imported epidemic.
