Background We aimed to compare the changes in seasonal respiratory viruses in the southern part Korean children between before pre-pandemic seasons (March 2018 to February 2020) and pandemic seasons (March 2020 to February 2022). Methods We retrospectively reviewed medical records of hospitalized children (0 to 18 years old) in whom seasonal respiratory viruses were detected using multiplex reverse transcriptase-polymerase chain reaction amplification in three centers from March 2018 to February 2022. Results Overall, 7,226 patients were enrolled. There were 6,090 patients in pre-pandemic seasons and 1,136 patients in pandemic seasons. Human rhinovirus and human adenovirus were continuously detected even after COVID-19 outbreak, there was one sample that influenza virus was detected. Parainfluenza virus (PIV) and respiratory syncytial virus (RSV) were almost disappeared in 2020. The PIV was detected from March to December in pre-pandemic seasons, and it was mainly prevalent from May to July. However, after the COVID-19 outbreak, in 2021, only PIV3 was detected from August to December, and it was mainly prevalent in September and October. The RSV was detected from August or September to May or June in pre-pandemic seasons, and it was mainly prevalent from October to February. However, after COVID-19 outbreak, in 2021, RSV was detected from November to February, and it was mainly prevalent in December and February. In PIV3 and RSV, comparing pre-pandemic seasons and pandemic seasons, patients in the pandemic seasons were older and the duration of hospital admission was longer in pre-pandemic seasons than in pandemic seasons. There were no significant differences in the history of underlying chronic diseases and clinical severity in PIV3 and RSV patients. Monthly distribution of seasonal respiratory viruses In pre-pandemic seasons, PIVs and HMPV were most commonly detected in spring and early summer, HBoV in late spring and early summer, RSV in October and winter, and IFV and HCoVs in winter. HRV (30.4%) ...
