Abstract：Objective To investigate the incidence characteristics of coronavirus disease 2019 (COVID-19) in Sichuan province, and to analyze its incidence trend. Methods The epidemic data regarding COVID-19 in Sichuan province from January 21 to March 9, 2020 were collected to conduct epidemiological descriptive analysis. Results The number of newly confirmed cases and suspected cases increased firstly and then decreased on the whole from January 21 to March 9, with the highest on January 30 and February 10, respectively. The cumulative number of confirmed cases initially rose steeply and then gradually slowed down. The number of newly cured cases fluctuated, and the cumulative number ofcured cases increased in a straight line. Among the cases cumulatively confirmed, the ratio of male to female was 1.21∶1. The average age of the confirmed cases was 43.47 years. The spatial distribution of the confirmed cases in Chengdu was the highest, followed by Garzê Tibetan Autonomous Prefecture, which accounted for 26.72% and 14.47% of the total confirmed cases in the whole province, respectively. Conclusions The incidence of COVID-19 in Sichuan province is stable at present, but it is also under pressure from enterprises to resume work, schools to resume schooling, and imported cases. Therefore, we should continue to enhance prevention and control of the epidemic so as to keep COVID-19 from rebounding.
