Prevention of Respiratory Syncytial Bronchiolitis.

Acute bronchiolitis is the leading cause of hospital admissions among infants worldwide and is associated with increased morbidity. The respiratory syncytial virus (RSV) is the most common causative agent and is often linked to a more severe and prolonged form than that caused by other viral agents. The annual outbreaks of bronchiolitis place substantial strain on pediatric emergency departments, hospital bed availability, and saturation of resuscitation beds. Most RSV bronchiolitis hospitalizations occur during the first three months of life in healthy term neonates. Management for RSV-related lower respiratory tract disease is mainly supportive. Recent advancements in RSV prevention strategies have emerged, including the approval of two new effective options: a maternal vaccine (RSVpreF) and a long-acting monoclonal antibody (Nirsevimab). The aim of this review is to screen recent literature and Tunisian data regarding RSV Bronchiolitis and summarize current evidence concerning knowledge and attitudes regarding RSV prevention strategies.
