A very low prevalence of SARS-CoV-2 infection but a high prevalence of other respiratory virus infections in children admitted to paediatric emergency departments.
Résumé
Aim
To investigate the prevalence of infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory viruses among children admitted to paediatric emergency departments (PEDs).
Methods
From April to July 2020, a prospective, multicentre cohort study was conducted in the PEDs of eight French university hospitals. Regardless of the reason for admission, a nasopharyngeal swab sample from each child was screened using reverse transcription polymerase chain reaction tests for SARS-CoV-2 and other respiratory viruses. We determined the prevalence of SARS-CoV-2 and other respiratory viruses and identified risk factors associated with a positive test.
Results
Of the 924 included children (median [interquartile range] age: 4 years [1–9]; boys: 55%), 908 (98.3%) were tested for SARS-CoV-2. Only three samples were positive (0.3%; 95% confidence interval: 0.1–1) and none of these children had symptoms of coronavirus disease 2019. Of the 836 samples (90%) tested for other viruses, 129 (15.4%) were positive (primarily rhinovirus). Respiratory viruses were significantly more common in young children and in children with respiratory tract symptoms and fever.
Conclusion
The prevalence of SARS-CoV-2 among children admitted to emergency departments was low. In contrast, and despite social distancing and other protective measures, the prevalence of other respiratory viruses detection was high.
