RSV IN YOUNG CHILDREN DURING AND AFTER THE COVID-19 PANDEMIC—IMPLICATIONS FOR DELAYING THE AGE OF FIRST INFECTION

Abstract

Nonpharmaceutical interventions introduced in the United Kingdom’s response to the COVID-19 pandemic disrupted the transmission of other childhood infections. We report changes in seasonality, age dynamics and severity of respiratory syncytial virus infections between 2019 and 2023. These data show the potential effects of delaying respiratory syncytial virus exposure and may provide insights for the implementation of treatments preventing infection during early infancy.
