A 3-year-old child has a runny nose and sneezing, suspected of having a cold due to wind-cold invasion. How should this be diagnosed and treated?

A 3-year-old child presenting with symptoms such as runny nose and sneezing may have a common cold caused by exposure to cold, but it could also be due to other respiratory infections or allergic rhinitis. In traditional Chinese medicine, a cold caused by exposure to cold refers to a series of upper respiratory symptoms triggered by chilling, including nasal congestion, clear nasal discharge, coughing, and is often accompanied by chills, headache, and other discomforts. As children's immune systems are not yet fully developed, they are more susceptible to colds during seasonal transitions.

Pay attention to whether the child also experiences symptoms like coughing, fever, or sore throat. Determine if the child has recently been in contact with anyone who had a cold or has been exposed to cold conditions. Closely monitor any changes in the child's condition; if symptoms persist or worsen, prompt medical attention is recommended. The physician will perform a thorough physical examination, such as auscultation of the lungs and examination of the nasal passages. Avoid the indiscriminate use of antibiotics to prevent the development of drug resistance. Administer medications only under the guidance of a physician to ensure safe and effective treatment.
