Coronavirus disease 2019 (COVID-19) bears several challenging problems, including insidious symptom onset, subclinical manifestations and highly transmissible property during early stage of infection.1 In the recent study by Huang et al., SARS-CoV-2-infection presented strong infectivity during the incubation period with rapid transmission.2 Some patients with COVID-19 are asymptomatic, while others complain of atypical symptoms including loss of smell and taste sense.3 However, there is insufficient data on the prevalence of asymptomatic infection and atypical manifestations of COVID-19.
