Off-season RSV episodes were more common among certain demographic groups and pediatric patients with high-risk conditions.
Off-season respiratory syncytial virus (RSV) episodes occur across the United States and may be more common among certain demographic groups and pediatric patients with congenital or chronic conditions, according to study results published in Open Forum Infectious Diseases.
Researchers conducted a study to identify characteristics of in-season (December-February) and off-season (June-August) RSV episodes. Patients included in the analysis were adults and children who were diagnosed with RSV infection in the pre-COVID-19 era (2017-2020).
Data were captured on patient demographic and baseline clinical characteristics, as well as comorbidities associated with increased risk for severe disease.
