Changes in Seasonal Patterns for Common Pediatric Respiratory Viruses During the COVID Pandemic.

Objectives: Observed alterations in seasonal patterns of common pediatric respiratory viruses during and immediately after the COVID-19 pandemic had far-reaching implications for the care of ill children. Here, we quantify the effects of the pandemic and related nonpharmaceutical interventions on the prevalence and seasonality of common pediatric respiratory illnesses.

Methods: We performed a retrospective chart review within a large health network to identify incidence rates of common respiratory viruses and compared them to historical trends.
