Correct answer: A — Admit for monitoring and give macrolide therapy with public health notification

Young infants with pertussis are at risk of apnoea and deterioration, so admission and macrolide therapy are appropriate with public health action. Antibiotics reduce transmission but may not rapidly alter established paroxysmal symptoms. Household contact management and timely immunisation remain important.
