The majority of acute respiratory infections (more than 90%) are caused by viruses. The most common respiratory viruses are influenza virus, parainfluenza virus, adenovirus, measles virus, mumps virus, rhinovirus, respiratory syncytial virus, rubella virus and coronavirus, etc. This is also the reason why doctors do not use antibacterial agents at the beginning of the fever, to check the routine blood, C-reactive protein to figure out the approximate direction of infection is a viral infection or bacterial infection, this test is still worth doing, the reason is self-explanatory. Virus is a class of tiny size, containing a type of nucleic acid (DNA or RNA), can only grow and reproduce in the living cells of non-cellular form of microorganisms. Influenza is an acute respiratory infection caused by the influenza virus and is clinically characterized by acute high fever, malaise, headache, and muscle aches, with a high incidence and ease of epidemic outbreaks. Usually, influenza is transmitted by airborne droplets from patients as the source of infection, and the onset is seasonal, with widespread susceptibility of the population and even a world pandemic. Influenza viruses are classified into three different types: type A, type B and type C, depending on the nucleoprotein antigen. Influenza A viruses are the most pathogenic and can infect a variety of animals, and are the main pathogen of human influenza, causing the largest scale of epidemics, and the majority of large-scale influenza epidemics around the world are caused by influenza A viruses; influenza B and C only infect humans, and influenza B is more localized epidemics or scattered outbreaks, while influenza C occurs mostly in children. Because the antigenic properties of influenza viruses change rapidly, people cannot obtain lasting immunity. Since the widespread use of antimicrobial agents, bacterial infections have been largely controlled without inhibiting viral effects, and other chemical drugs have not yet had definite effects on viruses. In the past hundred years, the harm caused by influenza pandemic has caused people to be extremely concerned about it, and many governments have taken emergency measures such as closing kindergartens, schools and public places during influenza pandemic to prevent or reduce the influenza pandemic. Second, how does modern medicine recognize influenza What are the symptoms of influenza? Generally speaking, the common symptoms are: children will be afraid of cold, cough, headache, sore throat, general tiredness, nasal congestion, runny nose, and even general body aches and pains, and physicians will find fever, inflammation of the throat, conjunctiva and nasal mucosa. Does western medicine reduce fever faster? Western medicine uses antipyretic and analgesic agents in the treatment of fever, which are needed for symptomatic treatment of high fever, but should be used wisely. Remember that this is only symptomatic, which means that the fever will return once the effect of the medicine is over before the cause is removed. The other thing is that Chinese medicine is really slow to reduce fever? I think when herpes pharyngitis was prevalent in May last year, I used Chinese medicine to reduce the fever by one or two payments. The fever will not recur unless there is a problem with the diet or the child kicks the covers in the middle of the night or sweats after playing outside and then feels the wind chill. This is because the virus has been invited to go out by sweating, vomiting, and the next method, not in the body to make trouble! Unlike Western medicine is acting on the thermoregulatory center, hard sweating makes the body temperature drop, the virus is still in the body; and the fever is recovered by the body’s natural victory over the virus, if you do not continuously take antipyretic and analgesic, the middle process will be repeated fever. If you do the math like this, will anyone still think that Chinese medicine is slower to reduce fever? One more thing to note: If a child has a fever, do not sleep on an ice pillow or rub the body with alcohol to cool it down, because sweating is required when you have an external wind chill, and if the skin pores contract even more as a result, it will be a hindrance for the herbalist to use medicine. If there are conditions, you can use a warm bath or take a warm shower to physically cool down the body to avoid the recurrence of wind chill. In addition, it is necessary to provide the physician with accurate information about the stool and urine, because constipation alone may cause a high fever that does not go away! In the traditional literature of Chinese medicine, the symptoms, characteristics and epidemic status of influenza have long been recorded. Influenza is called “seasonal flu” in Chinese medicine due to its widespread prevalence, and belongs to the category of epidemic (i.e. infectious disease). As early as 610 A.D. Sui Dynasty medical doctor Chao Yuanfang wrote the book “the source of all diseases”, it is proposed that “the seasonal diseases, which are due to the year, temperature and cool out of order, people feel the perverse gas and sick, multi-phase dye easy”. During the Ming and Qing dynasties, the theory and practice of Chinese medicine and therapeutics gradually matured, including a variety of acute infectious diseases, infectious diseases, the pathology, diagnosis and systematic prevention and treatment knowledge, so that the diagnosis and treatment of influenza in Chinese medicine has been enriched and perfected. In 1798, Wu Jutong, a Qing dynasty physician, created the pungent and cooling remedy “Yin Qiao San” in the book “Wenzhi Zhuan Zhi Zhi”, which became the main remedy for influenza in modern times. According to Chinese medicine, the onset of influenza is not only due to the invasion of external evil, but also related to the low resistance of the body to disease, especially when the climate is abnormal, cold and warmth are out of balance, it is more likely to develop. Chinese medicine attaches importance to the unity and harmony of the human body’s own integrity with the natural and social environment, and pays attention to the organic whole of internal and external links in health care and disease prevention and treatment to adapt to the natural and social environment. For influenza, TCM also aims to prevent and treat the disease by strengthening the body’s resistance to disease and adapting to the changes in the natural environment through evidence-based treatment, and eliminating the evil at the onset of the disease to improve symptoms, prevent transmission and promote early recovery. How does Chinese medicine deal with pediatric colds? In principle, TCM treatment of influenza must go through “look, smell, ask, and cut” before prescribing, that is, giving different Chinese medicines according to the patient’s physical symptoms. The common flu recently has chills, chills (called “cold and heat” in Chinese medicine), repeatedly high fever is difficult to go down, inexperienced parents feel quite frightened, some repeatedly fever for seven or eight days are there. If the treatment is combined with or based on TCM, the course of the disease will be much shorter and the occurrence of comorbidities or complications will be reduced. However, many parents think that TCM is a slow remedy and the advantage lies in conditioning, which is not true. Parents or children who have seen my patients should know this well. I would also like to address a common confusion: after seeing many flu patients, I found that there are some concepts that need to be established for parents: fever does not burn the brain unless it progresses to the stage of encephalitis and meningitis.
