Acute ITP is most common in which group?

Acute ITP is most common in which group?

• A. Adults after viral infection
• B. Children after viral infection
• C. Neonates with jaundice
• D. Elderly individuals with comorbidities

Answer: (B)

Acute immune thrombocytopenia most commonly presents in children after a viral infection. In kids, a recent viral illness or vaccination can trigger autoantibody production against platelet surface proteins, leading to rapid platelet destruction in the spleen. This causes the abrupt onset of mucocutaneous bleeding signs like petechiae and easy bruising. Most pediatric cases are self-limited, resolving within weeks to a few months. In adults, ITP tends to be more chronic and not as tightly linked to a preceding infection, and other groups (neonates with jaundice, elderly individuals with other illnesses) are less typical backgrounds for the acute form. So the group where acute ITP is most commonly seen is children following a viral infection.
