ABSTRACT
Bronchiolitis is a common seasonal viral illness in babies and children aged under two years. Its significance has increased in the light of a predicted surge in respiratory illness in children this winter and the continuing effect of the coronavirus disease 2019 (COVID-19) pandemic on parental anxiety and cross-infection. Children's nurses will have a central role in delivering high-quality care and support to children and families during this time. To support children's nurses to prepare for a surge, this article summarises the pathophysiology of bronchiolitis, risk factors, transmission, diagnosis and clinical management of children with the illness, including recent national policy changes. It also considers the potential effect of the COVID-19 pandemic on the healthcare system, children and families.
