1.**Risk of Secondary Infections**: Bronchiolitis can predispose affected individuals to secondary bacterial infections due to impaired mucociliary clearance and compromised lung function.This mucus, combined with cellular debris and inflammatory exudates, obstructs the airways, further impeding airflow.Additionally, areas of atelectasis (lung collapse) may develop due to airway obstruction and impaired ventilation.2.3.4.5.6.7.
