Finding: Parainfluenza virus (PIV) typically circulated in the spring, and respiratory syncytial virus (RSV) epidemic started in autumn in Korea before COVID-19 pandemic. PIV and RSV seasons disappeared in 2020 and came back in 2021 with atypical seasonality. PIV season was changed from spring to autumn, and the beginning of RSV season was slightly delayed from autumn to early winter in 2021.
