Objective To investigate the epidemiological characteristics of coronavirus disease 2019(COVID-19) in Shangqiu city so as to provide a basis for the next step in epidemic prevention and control. Methods We described the epidemiological characteristics of 91 COVID-19 confirmed cases reported in Shangqiu city as of March 4, 2020, and simultaneously analyzed their clinical features and etiological detection results. Results There were 44(48.35%) imported cases among the 91 COVID-19 confirmed cases in Shangqiu city. Most of the patients ranged in age from 18 to 59 years, accounting for 83.52%. Interpersonal transmission mainly occurred in families. Clinical classification showed that most of the cases were the general type, accounting for 65.93%. The curative rate and the mortality rate were 96.70% and 3.30%, respectively. The confirmed cases tested positive twice or more in nucleic acid tests accounted for 15.39%. 4(4.55%) discharged cases were re-tested positive in nucleic acid tests. Conclusions Initial progress has been made in prevention and control of the COVID-19 epidemic in Shangqiu city.
