Colds are divided into common colds and influenza, with sneezing, coughing and phlegm, runny nose, fever and headache as the main symptoms, with a tendency to spread, and should be promptly seen in the Department of Respiratory Medicine when a cold occurs; if fever (fever) is present, a visit to the Fever Clinic of the Department of Infection should be made first to exclude influenza. Usually, patients who are not feeling well go to the hospital and are advised to consult the respiratory medicine department according to the typical symptoms of their self-reported symptoms, and do blood tests, pathogenic tests, lung X-ray and other tests to diagnose the condition and confirm the diagnosis in combination with clinical symptoms. At the same time, with the aid of pathogenic tests, the common cold and influenza can be quickly identified, which will help the doctor to take effective treatment measures to relieve the symptoms of the patient. The treatment of cold is based on the principles of more rest, more water and more ventilation, and the medication is based on oral antipyretics, antivirals, cough syrup and other drugs. In addition, we should always pay attention to the occurrence of complications of cold, such as otitis media, septic pharyngitis, acute sinusitis, myocarditis, etc. If other complications occur, we will consult different departments according to different diseases. The cold heals quickly, and the symptoms usually disappear in 5-7 days, so you should pay attention to a light diet, avoid the intake of spicy and oily food, exercise properly, avoid activities in crowded places to reduce the incidence of the cold in late spring and autumn, and keep sufficient ventilation and light hours indoors.
