respiratory syncytial virus
Also written as: RSV — respiratory syncytial virus
A common viral infection causing bronchiolitis and pneumonia in infants and young children.
Full Definition
Respiratory syncytial virus (RSV) is a highly contagious virus that affects the respiratory tract and is the leading cause of bronchiolitis and pneumonia in children under two years of age. RSV infections typically occur in seasonal epidemics during fall, winter, and spring months. While most children experience mild cold-like symptoms, premature infants, those with congenital heart disease, or immunocompromised children are at higher risk for severe disease requiring hospitalization. Prevention strategies include palivizumab prophylaxis for high-risk infants.
Usage
