The first cases of coronavirus disease 2019 (COVID-19) were reported in Wuhan, China in December 2019 (Chen et al., 2020; Huang et al., 2020). The pathogen has been identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (Lu et al., 2020; Zhu et al., 2020). COVID-19 has rapidly become widespread across the world. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. From the end of February through March 2020, Daegu—the fourth largest city in South Korea—was emerging as an epicenter of COVID-19 in South Korea.
