Cough variant asthma in children is characterized by atypical symptoms, often manifested only as a cough. Bronchial asthma, or “asthma” for short, is the most common type of chronic respiratory disease in children. When asthma is atypical, it is called atypical asthma, and atypical asthma in which cough is the only symptom is called cough variant asthma. Cough variant asthma is usually characterized by a persistent cough for >4 weeks, with episodes or exacerbations during exercise, at night, or in the early hours of the morning, with a predominantly dry cough without wheezing, which resolves on its own, and is not responding to antibiotic treatment. Its diagnosis relies heavily on pulmonary function tests and the exclusion of other causes of chronic cough. Children who are suspected of having cough variant asthma should go to a regular hospital in time to get a clear diagnosis and then undergo targeted treatment, so as not to miss the opportunity for treatment.
