Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are children under two years old presenting with symptoms of bronchiolitis or lower respiratory tract infections.
✕Probably not a fit
Patients with a history of recurrent wheeze responsive to bronchodilators may not benefit from this study.

What this trial studies
This observational study investigates the effects of the COVID-19 pandemic on the incidence of bronchiolitis and respiratory syncytial virus (RSV) presentations in emergency departments. It focuses on children under two years of age who exhibit symptoms of bronchiolitis or lower respiratory tract infections. The study aims to understand how the absence of RSV during the pandemic may influence future cases as restrictions are lifted. By analyzing emergency department visits, the research seeks to provide insights into the potential resurgence of bronchiolitis in the post-pandemic period.
Why it matters
Potential benefit: If successful, this study could help healthcare providers better prepare for and manage bronchiolitis cases in children as COVID-19 restrictions are eased.
How similar studies have gone: While this study addresses a novel situation arising from the COVID-19 pandemic, similar studies in Australia have shown significant changes in RSV patterns, indicating potential relevance.
