• COVID-19 pandemic public health measures caused a 98% reduction in RSV cases during the 2020–2021 season. — Respiratory syncytial virus (RSV) notifications and trends in the transmission cycles from infants and young children to older adults in Ireland: an analysis of incidence shifts over a decade
• Pandemic-era infants had no opportunity to acquire RSV-specific immunity through natural exposure and were RSV-naive when restrictions lifted. — Respiratory syncytial virus (RSV) notifications and trends in the transmission cycles from infants and young children to older adults in Ireland: an analysis of incidence shifts over a decade
• The post-pandemic RSV resurgence from 2021 onward was characterised by higher incidence, earlier seasonal onset, and greater severity across multiple countries. — Respiratory syncytial virus (RSV) notifications and trends in the transmission cycles from infants and young children to older adults in Ireland: an analysis of incidence shifts over a decade
• Expanded multiplex PCR testing since 2020 contributed to higher reported post-pandemic RSV incidence and must be accounted for when comparing pre- and post-pandemic surveillance data. — Respiratory syncytial virus (RSV) notifications and trends in the transmission cycles from infants and young children to older adults in Ireland: an analysis of incidence shifts over a decade
• Infants who missed acquisition of maternal RSV antibodies due to reduced pandemic-era maternal exposure faced increased risk of severe RSV disease. — Respiratory syncytial virus (RSV) notifications and trends in the transmission cycles from infants and young children to older adults in Ireland: an analysis of incidence shifts over a decade
