The duration of the cough may vary depending on the cause of the cough and the patient’s own resistance. Coughs caused by common viral infections in life usually resolve themselves in about 1-2 weeks. Cough symptoms can occur for a variety of clinical reasons. In general, coughs caused by common infections with mild symptoms can improve in about 1-2 weeks. Once the cough has not improved for 2 weeks, it is important to be alert for bronchitis or pneumonia, tuberculosis, and other diseases. In addition, in cough variant asthma, the symptoms are usually relatively mild, and the cough can be completely reduced or disappeared within minutes by leaving the allergen and avoiding re-exposure. Usually severe infections, with bronchopneumonia or even lung abscess, lead to the appearance of a cough that requires active treatment and cannot be cured on its own. In addition, during coughing patients should take more rest, drink water regularly, avoid getting cold and chilled, and at the same time, actively give symptomatic treatment according to changes in their condition, and if necessary, they should be admitted to hospital for related treatment.
