Pediatric respiratory admissions and related viral infections during the COVID-19 pandemic

Abstract

Introduction: The COVID-19 pandemic has affected the incidence of respiratory viral infections. Our aim was to assess changes in pediatric admissions due to respiratory diseases and associated respiratory viral infections.

Methods: An observational study including all respiratory admissions to the pediatric departments from January 2015 to August 2021. We compared respiratory admission percentage, respiratory viral panel results and clinical characteristics of these admissions between two study periods, January 2015 to February 2020 (pre-COVID-19 era) and March 2020 to August 2021 (COVID-19 era).

Results: A total of 8774 respiratory admissions were included, 7157 pre-COVID-19 era and 1617 COVID-19 era. Relative to all pediatric admissions, there was a 17% decrease in respiratory admission percentage during the COVID-19 era (p < 0.001) and a 31% and 22% decreased in the admission percentages due to bronchiolitis (p < 0.001) and pneumonia (p < 0.001), respectively. However, admission percentages for asthma, wheezing illness, complicated pneumonia, and stridor remained the same. There was a significant decrease in the detection of a respiratory viral pathogen associated with these respiratory admissions (p < 0.001). This was related to a significant decrease in the detection of respiratory syncytial virus (RSV) (37% vs. 27%, p < 0.001) and influenza (5% vs. 0.3%, p < 0.001), but not other respiratory viruses. An alteration in the circulation pattern of most respiratory viruses, was observed.

Conclusions: During the COVID-19 pandemic, a decrease in the prevalence of RSV and influenza was associated with a significant decrease in admissions for bronchiolitis and pediatric pneumonia. This may allow us to estimate the significance of preventive measures for RSV and influenza on pediatric respiratory admissions.
