Characteristics of Children Hospitalized for Acute COVID-19 in France From February 2020 to December 2023

Abstract

We describe the characteristics of children hospitalized for coronavirus disease 2019 in France with a focus on the post-BA.1 Omicron period (February 2022-December 2023). We identified 3 main groups of children: those ≤90 days old (44.8%), older children with comorbidities (22.1%) and children with multisystem inflammatory syndrome (5.2%). Low vaccination coverage in these groups suggests that this burden could be alleviated with immunization.

Trial registration: ClinicalTrials.gov NCT04336956.
