%X <B>BACKGROUND: </B>At the end of 2019, a new epidemic of viral pneumonia emerged in China and was determined to be caused by a novel coronavirus, which was named coronavirus disease 2019 (COVID-19) by the World Health Organization. The epidemic quickly spread, causing a worldwide pandemic. Scientists and clinicians across the globe have shifted their research efforts towards understanding the virus itself and its epidemiology.<BR><B>METHODS: </B>In mid-January 2020, a Chinese family made a visit to a local city, and within the next 2 wk one after another fell ill with COVID-19. At the beginning of their first illness onset, the family had eaten in a restaurant, which led to the subsequent illness onset in another two families. All cases were diagnosed as COVID-19 by real-time fluorescent reverse transcription-polymerase chain reaction. Epidemiological investigation showed that the transmission chain was complete.<BR><B>CONCLUSIONS: </B>This chain of social exposure highlights the danger of group aggregative behavior for spread of COVID-19.
