Correct answer: B — Macrolide treatment with notification and contact prophylaxis assessment

Pertussis in young infants can present with apnoea and minimal fever; macrolide treatment reduces transmission and public health notification/contact management are required. Waiting for culture delays control measures. The pearl is that infant pertussis may be severe before the cough sounds classic.
