Post-COVID-19 Seasonality of Influenza, Respiratory Syncytial Virus, and SARS-CoV-2 Among Hospitalized Children in Western Iran: A Molecular Surveillance Study (2023–2024)

Findings reveal altered post-pandemic seasonality, reduced RSV activity, and low co-infection rates, suggesting potential ecological and immunological shifts. These trends highlight the need for sustained virus-specific surveillance and recalibrated vaccination strategies-particularly influenza vaccination in autumn and RSV prophylaxis in winter-in resource-limited pediatric settings.
