The characteristics of SARS-CoV-2-positive children who presented to Australian hospitals during 2020: a PREDICT network study

Abstract

To examine the epidemiological and clinical characteristics of SARS-CoV-2-positive children in Australia during 2020. Multicentre retrospective study in 16 hospitals of the Paediatric Research in Emergency Departments International Collaborative (PREDICT) network; eleven in Victoria, five in four other Australian states. Children aged 0-17 years who presented to hospital-based COVID-19 testing clinics, hospital wards, or emergency departments during 1 February - 30 September 2020 and who were positive for SARS-CoV-2. Epidemiological and clinical characteristics of children positive for SARS-CoV-2. A total of 393 SARS-CoV-2-positive children (181 girls, 46%) presented to the participating hospitals (426 presentations, including 131 to emergency departments [31%]), the first on 3 February 2020. Thirty-three children presented more than once (8%), including two who were transferred to participating tertiary centres (0.5%). The median age of the children was 5.3 years (IQR, 1.9-12.0 years; range, 10 days to 17.9 years). Hospital admissions followed 51 of 426 presentations (12%; 44 children), including 17 patients who were managed remotely by hospital in the home. Only 16 of the 426 presentations led to hospital medical interventions (4%). Two children (0.5%) were diagnosed with the paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). The clinical course for most SARS-CoV-2-positive children who presented to Australian hospitals was mild, and did not require medical intervention.
