In the outpatient clinic, there are often patients with colds and fevers who enter the clinic and ask for “doctor, give me an infusion” or “doctor, give me some anti-inflammatory medicine”. Recently, two family members of the doctor’s friends got sick, a 13-year-old child and an 82-year-old man with fever of about 39 degrees for 2-3 days, and before I saw the patients, they both used powerful antimicrobial infusions, resulting in increasingly low white blood cells. Upon closer questioning of the condition, both patients actually had viral upper respiratory tract infections (what the people call colds) and there was no need for anti-inflammatory drugs. About 80% of the upper respiratory tract infections are viral, and it is important to identify the evidence and take tonics or traditional Chinese medicine (as published earlier in “Did you choose the right cold medicine?) If the patient has a high fever, he/she should take rest and drink more warm water. If the patient has a high fever and cannot eat, he or she can be given fluids by infusion, but does not need to be given antibiotics. Elderly people with cold can easily induce other diseases, such as heart disease, cerebrovascular disease, severe pneumonia, etc., so pay attention to observation. If the fever does not subside for 3 days and the throat becomes more and more sore, we should pay attention to see if the tonsils are septic; if the cough becomes more and more severe, we need to take a chest X-ray to determine if it is pneumonia and check the blood routine, and if it is really combined with bacterial infection, we need to actively treat it with antibacterial agents. The common cold and fever does not require the routine use of anti-inflammatory drugs!
