Protracted bacterial bronchitis (PBB) is increasingly recognised as a cause of chronic cough in children.1 It is characterised by bacterial infection of the conducting airways that produces an antibiotic responsive wet cough.2 At our centre, children with suspected PBB are treated empirically with a 2-week course of amoxicillin/clavulanic acid.
