The study analyzes the impact of the COVID-19 pandemic on the epidemiology of respiratory syncytial virus (RSV) in Europe from October 2020 to September 2022.
Data from multiple surveillance systems showed a significant drop in RSV detections during the 2020/21 season, followed by a gradual increase in 2021 and notable peaks in 2021/22.
Despite increased testing, RSV patterns were disrupted, with unusual circulation trends observed, indicating that normalization of RSV activity had not been achieved by the 2022/23 season.
