Mild upper respiratory tract infections will heal on their own. Heavy upper respiratory tract infections require medication and other treatments to heal. 1. Upper respiratory tract infections are mostly caused by viruses. If the patient only has mild nasal congestion, runny nose, sore throat and other uncomfortable symptoms, it is usually self-limiting and can be cured by resting more, drinking more water, and exercising appropriately. 2. If the patient’s upper respiratory tract infection symptoms are heavy, accompanied by fever and bacterial infections such as combined bronchitis, acute tonsillitis, according to the patient’s specific conditions, the appropriate combination of anti-infective, cough, fever and other treatments, the upper respiratory tract infection can be cured. Mild upper respiratory tract infections may also be transformed into severe upper respiratory tract infections, and even involve the lower respiratory tract such as pneumonia, bronchitis, etc. During the onset of the disease, we need to pay attention to the temperature, nasal congestion, cough and sputum, and other symptomatic changes, and promptly go to the hospital for further consultation and timely treatment.
