Full Definition
Respiratory Syncytial Virus (RSV) is a common respiratory pathogen that affects nearly all children by their second birthday. While typically causing mild cold-like symptoms in healthy older children and adults, RSV can cause severe lower respiratory tract infections in infants, particularly those born prematurely or with underlying conditions. Bronchiolitis caused by RSV is a leading cause of hospitalization in infants under one year of age. The virus is highly contagious and spreads through respiratory droplets.
