Main Causes of Viral Bronchiolitis in Babies – Systematic Review

Abstract

Introduction: Acute bronchiolitis is almost exclusively caused by viral infection in children under 2 years of age. It is a secondary inflammatory viral infection of the lower airways, causing obstruction of the lower respiratory tract. Objective: Review the literature to verify the main causes of viral bronchiolitis in babies. Methods: This study constitutes a systematic review, classified as exploratory and descriptive. The preparation of the research was a bibliographical search in electronic databases on methods associated with RSL (Systematic Literature Review) and the applications of SMARTER (Simple Multi-Attribute Rating Technique using Exploiting Rankings). Results: A comprehensive systematic search of the literature yielded a total of 439 articles referring to the main causes of bronchiolitis in infants. Of these, 29 articles were eligible to be included in this systematic review. Conclusion: The study concluded that bronchiolitis research has seen a significant increase in research and publications, but further investigation is needed to improve our understanding and management of this condition.
