RSV is best described as what?

• A. Upper respiratory tract infection
• B. Lower respiratory tract infection
• C. Gastrointestinal infection
• D. Systemic infection

Answer: (B)

RSV predominantly affects the respiratory tract and is most classically a lower respiratory tract infection, especially in infants and young children. It inflames and narrows the small airways (bronchiolitis) and can lead to viral pneumonia, which are conditions of the lower airways rather than the nose, throat, or stomach. Clinically, this presents with cough, wheeze, tachypnea, chest retractions, and work of breathing, reflecting lower airway involvement. While RSV can start with milder upper respiratory symptoms, the hallmark concern and most impactful description in pediatrics is its tendency to cause lower respiratory tract disease. It is not primarily a gastrointestinal or systemic infection.
