Background: In the US, respiratory syncytial virus (RSV) is the leading cause of infant hospitalization and lower respiratory tract infections including bronchiolitis. Surveillance shows that since the start of the COVID-19 pandemic in March 2020, bronchiolitis and RSV-bronchiolitis epidemiology among US infants has been changing. Objective: To assess trends in hospitalizations and ICU admissions for infant bronchiolitis and RSV-bronchiolitis since the start of the COVID-19 pandemic, across four US health systems. Design/Methods: We assessed electronic health record (EHR) ICD-10-CM and laboratory testing data from the Duke University Health System, Renown Health System, USF Health/Tampa General Hospital, and SUNY Upstate Medical University from October 2015 to November 2022. Results: During the recent early 2022 RSV season, infant hospitalizations (Figures 1a, 1b), and ICU admissions and mechanical ventilation use (Figures 2a, 2b) for bronchiolitis and RSV-bronchiolitis have reached the highest levels since the start of our surveillance period in 2015.
Conclusion(s): The recent 2022 early bronchiolitis and RSV-bronchiolitis season has resulted in historically high levels of severe disease among infants. Continued monitoring of RSV-bronchiolitis trends is needed.
