There are many causes of fever in children, which can be clinically divided into infectious and non-infectious. Infectious causes are more common, such as colds. For fever, the cause must be identified first and treated accordingly.

Cold is also known as upper respiratory tract infection, abbreviated as upper respiratory tract infection, or common cold. It is a general term for acute inflammation of the nasal cavity, pharynx or throat. In a broad sense, upper respiratory tract infection is not a disease diagnosis, but a group of diseases, including the common cold, viral pharyngitis, laryngitis, herpetic pharyngitis, pharyngoconjunctival fever, and bacterial pharyngitis and tonsillitis. Upper respiratory tract infection in a narrow sense is also known as the common cold. It is the most common acute respiratory infectious disease. It is mostly self-limiting, but the incidence is relatively high. It occurs 2 to 4 times per year in adults and 6 to 8 times per year in children. The disease can occur throughout the year, but is more common in winter and spring.

Cold is a self-healing disease, which is generally divided into common cold and influenza. The common cold, called "cold" in traditional Chinese medicine, is a common respiratory disease caused by a variety of viruses, of which 30%-50% are caused by a certain serotype of rhinovirus. Although the common cold is more common in early winter, it can occur in any season, such as spring and summer, and the pathogenic viruses of colds in different seasons are not exactly the same. Influenza is an acute respiratory infectious disease caused by influenza virus. The virus exists in the patient's respiratory tract and is transmitted to others through droplets when the patient coughs or sneezes. If you have cold symptoms, you should contact your health manager in time so that you can take the correct measures to prevent infection and receive recovery treatment.
