The daily number of patients confirmed with COVID-19 in South Korea and Daegu city and the daily number of SARS-CoV-2 reverse transcriptase-polymerase chain reaction (RT-PCR) and patients with positive results in our emergency room (ER). The daily number of patients confirmed with COVID-19 in South Korea (blue line) and Daegu city (orange line) had reached the peak just after our ER shutdown. The daily number (gray bars) of SARS-CoV-2 RT-PCR and positive results (yellow bars) in our ER increased from the pre-shutdown period to the post-shutdown period.
