Abstract

(1)  CONCLUSIONS

  • During the COVID-19 pandemic, the historical seasonality of bronchiolitis and RSV-Br incidence has been disrupted.
  • 2022 trends indicate a return to typical seasonality, albeit early in the season.
  • Continued monitoring is needed to determine the impact of the pandemic on bronchiolitis and RSV-Br seasonality to aid future efforts at prevention and assess their impact

(2)  CONCLUSIONS

  • The recent 2022 early bronchiolitis and RSV-Br season has resulted in historically high levels of severe disease among infants.
  • Continued monitoring of RSV-Br trends is needed to assess the impact of future preventative measures on severe infant disease.
