Epidemiology and Transmission of COVID-19 in Shenzhen China: Analysis of 391 cases and 1,286 of their close contacts

Topic:

  • This report summarizes the epidemiology of 391 COVID-19 patients in Shenzhen China and 1,286 close contacts. Rather than reporting on cases identified through symptom surveillance, this study offers a better estimation of how COVID-19 looks more broadly in the population by relying on contact tracing. 
  • In addition to clinical details, findings indicate that household contacts and those travelling with known cases were at 6 and 7 times greater risk of infection, respectively, compared to those who were not household contact and not co-travelers. Children were found to be at similar risk of infection but not of severe illness.
