ObjectiveTo analyze the incidence and epidemic characteristics of local cases infected with SARS-CoV-2 in Yangpu District of Shanghai， China， and provide scientific evidence for the prevention and control of coronavirus disease-19 （COVID-19）.

MethodsDescriptive epidemiological methods were applied to analyze the epidemic data of all the patients tested positive for SARS-CoV-2 RNA in Yangpu District of Shanghai， China.

ResultsA total of 9 local cases （7 males and 2 females） were documented in Yangpu District from January 30， 2020 to February 29， 2020. The average age was （48.56±13.85） years old. According to the body mass index， the patients with overweight and obesity accounted for 44.44% of the total cases. All the patients had fever at the onset and radiological findings of pneumonia by CT examination. They were diagnosed during January 24 and February 8， 2020. The median incubation period of the COVID-19 was 9 days and the median course was 22 days. Six cases had travel history in the epidemic areas and the other 3 cases had history of contact with confirmed cases. There were two familial clusters， both of which were husband-wife relationships. One cluster had a clear temporal sequence of onset， while the other one might be co-exposed or mutually infected. No new local case infected with SARS-CoV-2 was evident since February 8， 2020.

ConclusionAll the local COVID-19 cases in Yangpu District have clear epidemiological exposure history. It warrants further attention to the family clustering SARS-CoV-2 transmission. Currently， containment of imported cases is crucial for the prevention and control of COVID-19 epidemic.
