INTRODUCTION The North Lisbon University Hospital Center was activated for referral of SARS-CoV-2 infected patients on the 11th March 2020 . The aim of this study is to describe the experience at the Department of Pediatrics in the approach and the clinical outcomes of infected children . MATERIAL AND
METHODS A descriptive observational study was performed . Children and adolescents (0 to 18 years) with SARS-CoV-2 infection, diagnosed in the emergency room or admitted to the Department of Pediatrics between March 11th and June 18th, were included . Hospital records and Trace COVID-19 platform were reviewed and patient caregivers were interviewed to assess follow up .
RESULTS Among 103 diagnosed children, 83% had a known previous contact with an infected patient , 43% presented fever and 42% presented respiratory symptoms . Ten percent had risk factors and 21% were aged under one year old . Ten percent were hospitalised, one needing intensive care, with paediatric inflammatory multisystem syndrome . Blood tests were performed in 9% and chest radiograph in 7% . No children required ventilation, antiviral therapy or underwent thoracic computed tomography scan . Eight percent of children returned to the emergency room and one child was hospitalised . The clinical outcome is known in 101 patients and is favourable in all .
DISCUSSION Most children had an epidemiological link and little clinical repercussion, even during the first year of life . The expected mild severity in children justified the use of established clinical criteria and recommendations for similar conditions, regarding tests and hospitalizations . No antiviral treatments were given due to lack of evidence of its benefits .
CONCLUSION This strategy contributed to a low consumption of hospital resources and proved safe in this series.
