Abstract：Objective To learn the epidemiological characteristics of coronavirus disease 2019（COVID-19）in Huzhou,so as to provide reference for prevention and control of COVID-19. Methods All the confirmed cases of COVID-19 in Huzhou,diagnosed according to the COVID-19 Diagnosis and Treatment Plan（Sixth Version Trial）and reported from January 25 to February 7,2020,were recruited. The process of diagnosis and treatment,clinical manifestation,exposure history and close contacts were collected to analyze the epidemiological characteristics. Results On January 25,the first confirmed cases of COVID-19 in Huzhou was reported. By February 7,totally 10 confirmed cases were reported and no asymptomatic infection was found. They were all imported,including three Wuhan residents,two with a trip to Wuhan,three with a trip to Suizhou,one with a trip to Hangzhou and one with a trip to Thailand（two Wuhan passengers on the same flight）. The ratio of male to female cases was 1∶1. The median age was 32 years old. Seven cases were found when they went to a doctor by themselves,and three cases were found during the quarantine. The main clinical manifestations were fever,dry cough and fatigue. The median time from onset to diagnosis was 3 days. By March 3,all the cases were discharged,with median course of 24 days. There were 312 close contacts,and all of them were released after 14 days of quarantine. Conclusions To prevent imported cases from outside and stop spread inside taken by Huzhou government was proved to be effective. All the COVID-19 cases in Huzhou were imported,mostly from Wuhan. No local cases were reported.
