Correct answer: E — Urgent specialist advice for post-exposure prophylaxis

An immunocompromised child exposed to varicella needs urgent specialist assessment for post-exposure prophylaxis. Waiting for rash risks severe disseminated infection. Aspirin should be avoided in children with viral infections because of Reye syndrome risk. The pearl is that exposure management matters as much as rash management in vulnerable children.
