Bronchitis and bronchiolitis in children

Bronchiolitis, the leading cause of lower respiratory tract infection in infants and young children, is characterized by inflammation and obstruction of the small airways. This abstract outlines key areas of ongoing research aimed at improving our understanding, diagnosis, treatment, and prevention of this common illness. Investigations into viral pathogenesis, host immune responses, and airway physiology continue to refine our knowledge of disease mechanisms. While supportive care remains the cornerstone of management, research explores the efficacy of various therapies, including bronchodilators, corticosteroids, and hypertonic saline, with a focus on identifying effective interventions for specific patient subgroups
