Acute ITP in children is described as which, and is usually related to a viral infection?

• A. Self limited, bacterial infection
• B. Acute, viral infection
• C. Progressive, autoimmune
• D. Self limited, viral infection

Answer: (D)

Acute ITP in children is best described as self-limited and often related to a recent viral infection. In kids, the condition typically follows a viral illness and presents with sudden thrombocytopenia and mucocutaneous bleeding, but the immune-mediated destruction of platelets usually remits on its own within weeks to months. This post-viral immune response leads to antibodies or immune cells that tag platelets for destruction, most commonly in the spleen, rather than indicating a progressive, ongoing autoimmune disease. That combination—a brief, self-resolving course after a viral trigger—fits the pediatric pattern far better than a bacterial trigger or a progressive autoimmune process.
