Persistent cough after recovering from COVID-19

Persistent cough after recovering from COVID-19 is usually due to damage to the airway mucosa and typically lasts about two weeks, although individual differences exist. Patients are advised to seek timely medical evaluation and treatment at a hospital. For those with severe cough symptoms, it is recommended to take expectorant medications such as ambroxol hydrochloride tablets or bromhexine tablets under a doctor's guidance to alleviate discomfort.
