Cold, a self-healing disease, is generally divided into the common cold (cold) and influenza (influenza, epidemic influenza, grippe). The common cold, called “wind” in Chinese medicine, is a common respiratory disease caused by a variety of viruses, 30%-50% of which are caused by a certain serotype of rhinovirus. Although the common cold mostly occurs in early winter, it can also occur in any season, such as spring and summer, and the viruses that cause the cold in different seasons are not exactly the same. Influenza is an acute respiratory infection caused by the influenza virus. The virus is present in the patient’s respiratory tract and is transmitted to others via droplets when the patient coughs or sneezes.
