Abstract
Acute Viral Bronchiolitis (AVB) is a common respiratory infection in infants, with Respiratory Syncytial Virus (RSV) being the main etiological agent. The disease can progress to severe cases, requiring hospitalization, especially in high-risk groups. Diagnosis is clinical, with advances in PCR usage. Treatment is supportive, and new strategies, such as immunoprophylaxis, are being studied. Research suggests a possible link between AVB and future respiratory diseases, reinforcing the need for management and prevention strategies. This study aims to explore recent advances in the diagnosis, treatment, and prevention of AVB. The Scielo and PubMed indexers were used as search engines for article selection, with the keywords “Acute Bronchiolitis; Bronchiolitis; Pediatrics.” It is concluded that acute viral bronchiolitis is a common and challenging respiratory infection in pediatrics, especially in infants and vulnerable groups. Diagnosis, enhanced by technologies such as RT-PCR, aids in identifying viral agents. Treatment is supportive, avoiding unnecessary interventions. The disease may increase the risk of childhood asthma, requiring further research. Preventive strategies, such as palivizumab and hygiene measures, are essential. Scientific advances may lead to new approaches, reducing the impact of bronchiolitis and improving pediatric care.
