Starting from South Africa to the United Kingdom and Europe, then the United States "Omi Keron" is sweeping the world, and "Omi Keron" in Tianjin on the mainland has also caused a local epidemic, and the world seems to be shrouded in a tense atmosphere. But both real-world data and laboratory research tell us that "Omi kerong" is a widely circulating but limited variant of the new crown virus. Where does "Aumi Kerong" come from, what kind of impact does "Aumi Kerong" have on the respiratory system, and what prevention and control methods should we take?
Recently a doctor in the United States told his situation, although he worked in the emergency room for two years, he encountered a lot of new crown patients every day, but he was not infected because of good protective measures, he also received two new crown vaccines half a year later and then gave a booster injection, he was in his 40s and did not have any other chronic diseases, nor did he take any medicine, but because of the work relationship, he had to be vaccinated, did not expect that when he received the booster injection for nearly two and a half months, That is, close to the New Year of 2022, he felt headaches and fatigue, began to think that the work was too tired and sleepless, did not expect to go to sleep the next day when the throat began to itch and start to run a nose, so he quickly did a nucleic acid test, the result was positive, and although the family had taken vaccines and vaccine enhancement injections, the tests were also positive, and at this time, the "Omi Kerong" in the United States had accounted for more than 95% of the new crown patients.
Then from his symptoms, there is no loss of taste and smell, there is no fever, and after 5 days the symptoms basically disappear is the residual feeling of some headache and fatigue. Some teachers may think that he is fortunate to have the new crown vaccine, and the strengthening injection, so his symptoms are so light, in fact, we do not know whether this is the reason why his symptoms are relatively mild, but all the people infected with "Omi Kerong", including those who have not been vaccinated, or the vaccine effect has dropped to a very low level, their symptoms after infection are also very light, from the relevant statistics, although the number of new crown infections has reached an unprecedented record, But hospitalizations and deaths have not grown proportionally as before, and have remained at a lower level than the previous three waves of infections, in stark contrast to past variant virus infections.
So why did "Omikron" produce results so differently? Isn't it a variant of the Delta virus?
In the past, a popular saying was to suspect that the "Delta" virus infected patients with chronic AIDS produced the "Omikejong" variant, but a study from the Chinese Academy of Sciences found that the various characteristics of the "Omikejong" variant were more like variants of the new coronavirus in the early days, and the researchers speculated that the new coronavirus was first transmitted from mice to people, and then from humans back to mice, and mutated in mice, becoming the current "Omikejong" and then transmitted to people, that is, "Omikejong" It is not a variation from previous variants, which may mean that vaccines that have been effective against other variants of the virus in the past have had a very limited effect on "Omikron".
So why are their infections so strong? Researchers have studied some of the upper respiratory tract mucosal cells donated by patients infected by "Omikejong", and found that the expression of the ACE2 receptor gene on the cell membrane is very active, and the spike protein of the new coronavirus must be bound to the ACE2 receptor to enter the cell, but the light binding is not enough, but also through a serine protease that allows the virus to cross the cell membrane to transport the virus from outside the cell to the inside of the cell to complete the infection of the cell, "Omiljung" also makes the gene expression of this serine protease enhance a lot, This makes "Omikeron" 70 times more contagious than the "Delta" virus, but this change occurs mainly above the bronchi and rarely affects the lungs, in other words, "Omikeron" causes results more like an upper respiratory cold than pneumonia.
Researchers found that other variants of the new coronavirus can be effectively replicated in Syrian hamsters but the lungs of Syrian hamsters infected by the "Omikejong" variant virus have low viral RNA stocks and no infectious viruses, and pathological examination of the lung tissue of hamsters infected with "Omikejong" did not find inflammation or signs of bronchial pneumonia around the bronchi, and scientists in the United States and Japan also found that compared with the past variant viruses, "Omikron" was also found to be compared with the past variant viruses. Infected mice and hamsters have mild symptoms of both upper and lower respiratory tract infections and show no signs of weight loss.
But all of us still can not take it lightly, although the symptoms of "Omikejong" are relatively mild but its long-term impact on our body is not clear, everyone's physical condition and congenital physique are not the same, so the prevention and treatment of "Omikejong" infection is still very important, especially in the current vaccine can not be 100% effective protection of us in the case we especially need to pay attention to prevention, then first of all we must ensure a normal healthy lifestyle diet is regular, avoid drinking canned drinks, junk food High-sugar foods should increase plant protein and healthy fat vitamin C vitamin D3 trace elements zinc magnesium and selenium, which are very effective in our immunity against the new crown virus. And the strength of autoimmunity is undoubtedly the most powerful weapon against the new crown (whether it is "Omicron" or "Delta") !
Then for medical institutions, "Aomi Kerong" will undoubtedly cause a sharp rise in prevention and control pressure due to its strong spread, but whether it is "Aomi Kerong" or "Delta" is a respiratory infectious disease, its prevention and control strategy is the same, so it is undoubtedly the most important to grasp and implement the existing prevention and control measures.
