Abstract Post-infectious cough is a common diagnosis in people with chronic cough. However the specific infectious aetiology and cough mechanisms are seldom identified. We report a case of chronic cough after Mycoplasma pneumoniae lower respiratory tract infection with extrathoracic airway hyperresponsiveness as the cough mechanism. Extrathoracic airway hyperresponsiveness may be a common mechanism in post-infectious cough which may be useful both diagnostically and therapeutically since chronic cough with extrathoracic airway hyperresponsiveness responds to speech pathology treatment. Background Post-infectious cough is a common diagnosis especially in primary care settings although a specific infectious aetiology is rarely confirmed. Aside from pertussis the role of other infectious agents in chronic cough is poorly understood. In specialist
