Coronavirus disease 2019 (COVID-19) is an acute respiratory disease with an incubation period of 1 to 14 d, which is caused by a novel coronavirus (SARS-CoV-2), which has spread throughout China and worldwide. Different from SARS, MERS, and influenza, the dominant clinical manifestations of COVID-19 are fever and cough, whereas upper respiratory symptoms and gastrointestinal symptoms are rare. Moreover, the elderly and those with underlying diseases become more seriously ill after infection[1]. SARS-CoV-2 is highly transmissible in humans and is characterized by a risk of nosocomial transmissions[2]. Compared with the general population, healthcare workers (HCWs) are a special population who have a particularly higher risk of acquiring COVID-19 infection because they are exposed to biological risk factors during their daily work.
