Impact of COVID-19 on testing, positive cases, patient characteristics, and hospital contacts for respiratory syncytial virus, influenza, and pneumococcus in Danish children

The study highlights the impact of COVID-19 interventions on the epidemiology of pediatric respiratory infections, revealing a pattern of decreased incidence during lockdowns followed by a resurgence. More tests were carried out among an increasing proportion of healthy individuals. Such changes in testing practices and changing characteristics of tested populations have implications for understanding post-pandemic infection trends and healthcare resource allocation.
