Abstract: Objective There were 47 confirmed cases of coronavirus disease 2019(COVID-2019)reported in Jinan City from January 23 to February 11, 2020. Since February 25, 2020, there were no confirmed cases reported in Jinan City for 14 consecutive days. In order to provide reference for future epidemic prevention and control, we analyzed the current epidemic situation and epidemiological characteristics. Methods The demographic, clinical and epidemiological characteristics of confirmed cases in Jinan City were evaluated with descriptive analysis and family clusters were traced. Results 74.5% of 47 confirmed cases were clinical common type, and 24(51.1%)were cured and discharged. No death occurred. Fever(66.0%)was the first dominant symptom. CT showed 82.1% of the cases were bilateral pneumonia. The distribution of cases was similar between male and female. Most patients(70.2%)aged 20 to 59 years, 83.0% lived in the central urban area, and 40.4% had a history of Wuhan exposure before onset. Five of 10 family cluster outbreaks were sourced from Wuhan exposure. 70.2%(33 cases)of 47 cases were related to the family cluster outbreaks. Conclusion The epidemic prevention and control work in Jinan City has achieved phased results. Preventing importation from surrounding areas and high incidence risk areas is still the focus of future efforts.
