Cold, scientifically known as “upper respiratory tract infection”, is characterized by early symptoms of sneezing and runny nose followed by sore throat and fever. The symptoms usually disappear within a week. Some patients may develop symptoms of acute bronchitis, such as coughing and sputum, in the later stages. The most common pathogens of colds are viruses, such as parainfluenza virus, rhinovirus, coronavirus, respiratory syncytial virus, etc., followed by some bacteria, such as Haemophilus influenzae, streptococcus, Staphylococcus aureus, etc. There are also rare causes such as some atypical pathogens – such as mycoplasma, chlamydia, etc. The vast majority of colds heal on their own. The use of medications or not has little impact on the final prognosis of the patient. From this point of view, most colds can be treated “without medication”. However, for some elderly people with low resistance and chronic diseases, if the early cold is not treated actively, the subsequent lung infection or aggravation of the original disease can have serious consequences. Therefore, from this perspective, colds should be treated aggressively. Influenza A (H1N1)”, which is currently a worldwide concern, is also a cold in a broad sense. The neuraminidase inhibitor – Tamiflu is a special drug for the treatment of this influenza virus, used within 48 hours of onset, can effectively shorten the course of the disease and reduce the emergence of comorbidities. As you can see, the prognosis is very different when treated with medication. In conclusion, the traditional view is that for most healthy young adults with mild flu symptoms, treatment can take the form of more rest and more water, and medication can be used sparingly or even not at all. For those who are older and suffer from chronic diseases, early medication is advocated to avoid comorbidities. For larger-scale influenza, both men and women, young and old, should be treated early and aggressively. I have observed a phenomenon in my clinic that many young and middle-aged patients have a dry cough for weeks or even months, although the symptoms of nasal congestion, runny nose and fever are quickly relieved. Preliminary studies have found that there may be a close relationship between the lack of medication early in the cold and this “post-infectious cough”. It is clear that even for young adults, early medication for colds is necessary. Anti-viral drugs and antibiotics are allopathic drugs, except for influenza virus, and it is not recommended to use “Ribavirin, Amantadine “The use of antiviral drugs such as ribavirin and amantadine is unnecessary and ineffective. Antibiotic treatment should be aimed at the elderly and patients with chronic diseases. Our common drugs such as “Contec, day and night Benadryl, Sensacare” are all “allopathic” drugs and can be used safely by all kinds of people if there are no contraindications.
