The first case of coronavirus disease reported in South Korea was a person infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), who entered South Korea from China on January 20, 2020. In the Capital, the Korean government applied the social distancing policy at level 2.5 for 8 days from August 30 to September 6, 2020. The Central Disease Relief Center explained that the reason the number of newly confirmed cases per day did not fall below 100 was because the infection spread nationwide through sporadic mass infections or asymptomatic patients. Asymptomatic infection with SARS-CoV-2 is a subject of constant controversies, as asymptomatic patients can infect other people while not showing any symptoms themselves. Their atypical clinical characteristics in the early stages of the disease make prevention more difficult. Additional studies on the infecting power of SARS-CoV-2 in asymptomatic cases are needed. Nonetheless, such probabilities should be taken into consideration and we should remain vigilant.
