Impact of the COVID-19 pandemic on healthcare-associated viral respiratory infections at a tertiary care pediatric hospital.

The incidence of healthcare-associated viral respiratory infections in a pediatric hospital decreased from 1.6 /1,000 patient-days in 2019 to 0.2 /1,000 patient-days in 2020 (P < .01), and this was maintained in 2021 despite an increase in community circulation of respiratory viruses. Universal masking, stricter infection control measures, and pandemic public health interventions likely accounted for this improvement.
