We therefore evaluated pre\u2010admission screening for severe acute respiratory syndrome coronavirus 2 (SARS\u2010CoV\u20102), respiratory syncytial virus (RSV) and influenza during the COVID\u201019 pandemic, comparing epidemiology and clinical features of admitted children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Children were screened at a paediatric emergency department from 1 March 2020 to 30 June 2022 by nasopharyngeal sampling and polymerase chain reaction kit.

Of these, 29 (5.6%), 26 (24.1%) and 245 (44.8%) were incidental findings, lacking symptoms of infection. RSV and influenza A were initially absent but re\u2010emerged in the autumn of 2021. The rate of COVID\u201019 rose when the Omicron variant emerged in December 2021. The median age of children with RSV was 0.3\u2009years, of those with influenza A 6.7\u2009years and of those with COVID\u201019 1.6\u2009years.
