Low levels of respiratory syncytial virus activity in Europe during the 2020/21 season: what can we expect in the coming summer and autumn/winter? Eurosurveillance: 2021, 26(29), nr. 2100639
* Since the introduction of non-pharmacological interventions to control COVID-19, respiratory syncytial virus (RSV) activity in Europe has been limited.
* Surveillance data for 17 countries showed delayed RSV epidemics in France (≥ 12 w) and Iceland (≥ 4 w) during the 2020/21 season.
* RSV cases (predominantly small children) in France and Iceland were older compared with previous seasons.
* We hypothesise that future RSV epidemic(s) could start outside the usual autumn/winter season and be larger than expected.
* Year-round surveillance of RSV is of critical importance.
