Full Definition
Respiratory Syncytial Virus is a common respiratory pathogen that infects most children by their second birthday. While typically causing mild cold-like symptoms in healthy older children and adults, RSV can lead to serious complications in infants, especially those born prematurely or with underlying medical conditions. It is the most common cause of bronchiolitis and pneumonia in children under one year of age and the leading cause of hospitalization in this age group during winter months.
