Recurrent cough in children can be seen in recurrent respiratory infections, cough variant asthma or upper airway syndrome, etc. It usually cannot be cured by itself, and appropriate interventions need to be made according to the cause of the recurrent cough. 1. Recurrent respiratory infections: If acute or chronic bronchitis occurs repeatedly, the above mentioned symptoms may appear, and usually cannot be cured by itself, and reasonable interventions are needed, such as paying attention to strengthening nutrition and exercise to enhance physical fitness, and treating suspected bacterial infections with a reasonable and full course of medication, avoiding discontinuation of medication on one’s own, and so on. 2. Cough variant asthma: recurrent cough can occur, usually the effect of anti-infective treatment is poor, such children need to standardize the nebulizer treatment, often use inhaled glucocorticosteroids (such as budesonide), the use of leukotriene receptor antagonists (such as montelukast) to reduce airway reactivity, and need to pay attention to avoid daily contact with suspected allergens. 3. Upper airway syndrome: such as rhinitis – sinusitis, due to nasal secretion reflux stimulation of the respiratory tract, recurrent cough, often accompanied by nasal congestion, runny nose, etc., the treatment requires the use of physiological sea saline nasal rinsing, nasal glucocorticoid (such as mometasone furoate) for the local spray, reduce nasal inflammation and edema, and the use of antibacterial drugs (such as amoxicillin), as appropriate, anti-infection treatment. 4. Others: environmental stimuli, such as passive smoking; other systemic diseases, such as gastroesophageal reflux cough. All of the above medications should be used under the supervision of a physician, and it is recommended to actively seek medical attention and evaluation by a specialist physician for reasonable intervention.
