Hospitalisation, morbidity and outcomes associated with respiratory syncytial virus compared with influenza in adults of all ages.

Background: Respiratory syncytial virus (RSV) is understood to be a cause of significant disease in older adults and children. Further analysis of RSV in younger adults may reveal further insight into its role as an important pathogen in all age groups.

Methods: We identified, through laboratory data, adults who tested positive for either influenza or RSV between January 2017 and June 2019 at a single Australian hospital.
