This work describes the epidemiology of respiratory syncytial virus (RSV) observed during two winter seasons (weeks 40\u201320) and inter\u2010seasonal periods (weeks 21\u201339) during the pandemic between October 2020 and September 2022.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Using data submitted to The European Surveillance System (TESSy) by countries or territories in the World Health Organization (WHO) European Region between weeks 40\/2020 and 39\/2022, we aggregated country\u2010specific weekly RSV counts of sentinel, non\u2010sentinel and Severe Acute Respiratory Infection (SARI) surveillance specimens and calculated percentage positivity. Results for both 2020\/21 and 2021\/22 seasons and inter\u2010seasons were compared with pre\u2010pandemic 2016\/17 to 2019\/20 seasons and inter\u2010seasons.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Although more specimens were tested than in pre\u2010COVID\u201019 pandemic seasons, very few RSV detections were reported during the 2020\/21 season in all surveillance systems. During the 2021 inter\u2010season, a gradual increase in detections was observed in all systems. In 2021\/22, all systems saw early peaks of RSV infection, and during the 2022 inter\u2010seasonal period, patterns of detections were closer to those seen before the COVID\u201019 pandemic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>RSV surveillance continued throughout the COVID\u201019 pandemic, with an initial reduction in transmission, followed by very high and out\u2010of\u2010season RSV circulation (summer 2021) and then an early start of the 2021\/22 season.
