Dear Editor,

In China, the epidemic of COVID-19 has been temporarily brought under control due to strong measures, while there are few new cases except some imported ones (https://static.wecity.qq.com/wuhan-haiwai-pre/dist/index.html#/). The PCR-based test result combined with clinical symptoms has widely been used for the detection and confirmation of COVID-19.1 However, the prevalence of asymptomatic or subclinical SARS-CoV-2 infection in China remained unknown.
