ABSTRACT
OBJECTIVES: Reports from China relating to coronavirus disease (COVID-19) in children indicate a milder disease course compared with adults. Although a few pediatric COVID-19 reports from other parts of the world exist, there are none from the United Kingdom. We describe the clinical characteristics of children with COVID-19 admitted to a specialist children's hospital in United Kingdom. METHODS: Retrospective case-series of inpatients with a positive polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2, during a 6-week period from March 14 to April 24, 2020. RESULTS: Forty-five children tested positive for severe acute respiratory syndrome coronavirus 2 during the study period. Median (interquartile range) age was 3.5 (0.7-12) years, and 31 (69%) were male. Children with comorbidities constituted 64% (29 of 45) of the study population, including 44% (20 of 45) who were considered "extremely vulnerable." Fever (67%) and cough (55%) were the most common symptoms. High C-reactive protein (>10 mg/L) was observed in 68% (19 of 28). Lymphopenia (<1.2 × 109/L) was observed in 23% (9 of 40) of children, but it was related to coexisting medical conditions in 6 children. Nine children required supplemental oxygen, two of whom received high-flow nasal cannula oxygen; one needed noninvasive ventilation and one child required invasive mechanical ventilation. Median length of stay of children with an admission outcome (n = 42, 93%) was 3 (2-7) days. There were no COVID-19-related deaths. CONCLUSIONS: COVID-19 had a relatively mild course of illness in majority of the hospitalized children that included a subgroup of vulnerable children with significant comorbidities. Confirmation of this in larger nationwide studies of children is required.
