Upper respiratory infections are mostly caused by pathogenic microorganisms. They are related to factors such as exposure to cold weather, low immunity, weak resistance, frequent staying up late, and excessive fatigue. Additionally, viral infections, such as influenza virus, adenovirus, rhinovirus, and Coxsackievirus, can also cause upper respiratory infections. Some may be due to bacterial infections. Therefore, it is recommended that everyone should actively seek symptom-targeted treatment under the guidance of a doctor, and it's important to identify the cause and develop an appropriate treatment plan based on test results. Key to the treatment is the active cooperation of the patient with the doctor's plan. In terms of diet, it is advised to eat light foods, drink plenty of water, rest adequately, and avoid spicy, greasy, raw, cold, and irritating foods. Smoking and drinking alcohol should also be avoided while actively cooperating with the treatment.
