RSV bronchiolitis
Respiratory syncytial virus-induced inflammation of small airways in infants, typically requiring supportive care and careful monitoring for respiratory distress.
Full Definition
Bronchiolitis caused by respiratory syncytial virus, the most common cause of lower respiratory tract infection in infants under 12 months. Clinical presentation includes rhinorrhea, cough, wheezing, and respiratory distress. Diagnosis is often clinical but may be confirmed with rapid antigen testing or PCR. Treatment is primarily supportive with oxygen therapy, hydration, and monitoring. High-risk infants (premature, immunocompromised, or with congenital heart disease) may require hospitalization. Editorial review should verify proper virus name spelling and appropriate use of diagnostic terminology.
Usage
Usage note: RSV should always be spelled out as 'respiratory syncytial virus' on first mention.
