Community Transmission of Severe Acute Respiratory Syndrome Coronavirus 2, Shenzhen, China, 2020

I n December 2019, an outbreak of a novel corona- virus infection , occurred in Wuhan, China (1). Although China launched an emergency response early in the outbreak, the infection rapidly spread to metropolitan areas in China and around the world. The growing number of cases suggests that the epidemic has continued to spread. Several research articles have reported the epidemiologic characteristics of the outbreak in Wuhan and Hubei Province (1-4); however, to our knowledge, an analysis of the epidemic in metropolis areas around Wuhan has not yet been reported. To predict the epidemic trend and guide control measures, especially in similar metropolitan areas, outbreak investigations are needed.
