Seasonality, clinical characteristics, and outcomes of respiratory syncytial virus disease by subtype among children less than five years old, New Vaccine Surveillance Network, United States, 2016-2020
Description
CONCLUSION: Findings indicate that RSV-A and RSV-B may only be marginally clinically distinguishable but both subtypes are associated with medically attended illness in children <5 years old. Furthermore, circulation of RSV subtypes varies substantially each year, seasonally and geographically. With introduction of new RSV prevention products, this highlights the importance of continued monitoring of RSV-A and RSV-B subtypes.
