Cough variant asthma

Cough type asthma, also known as cough variant asthma, refers to a special type of asthma with chronic cough as the main or only clinical manifestation. When the onset of bronchial asthma begins, about 5% to 6% are with persistent cough as the main symptom, which usually occurs at night or in the early morning, and is often an irritating cough. At this time, it is often misdiagnosed as bronchitis. In recent years, this problem has attracted the attention of many scholars at home and abroad, and found that among the single causes of chronic cough, asthma accounts for 24%, ranking second, and 28% of asthma patients have cough as the only clinical symptom.
