The coronavirus disease 2019 (COVID-19) which started in Wuhan, China, and affected most of the country, is spreading rapidly throughout the world in spite of the concerted efforts from the governments and World Health Organization (WHO) to contain it. The virus spreads 1000 times faster than the other viral strains inside the body and causes various kind of illnesses [1]. Korea is also adversely affected by COVID-19 due to its geographical proximity to China. Considering the high attack rate and aggressive spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is a concern that more serious diseases may develop due to a mutated type of the virus. Some treatment experiences in Korea suggest that steroids played an important role in the treatment of COVID-19. According to reports from China, although pneumonia was rare in the pediatric population, the risk of pneumonia increased with age and had a high mortality rate among the elderly in their 70s (8.0%) and 80s (14.8%) [2].
