What is the situation of people who #还没 "impotent" #
Nowadays, the vast majority of people in the country have deeply experienced the different symptoms brought about by the new crown, such as lingering cough, "blade voice", "cement nose", body aches, high fever and other discomforts.
But many friends have also found that there are some people around who have not been infected until now, the whole family is "yang", the baby is not "yang", this is the case in our family. Living in the "flock", the rest of the family is all infected, he still goes downstairs every day to exercise and play, but he is still not good. What's going on here? Is this the legendary "chosen cook"?
Li Lanjuan, an academician of the Chinese Academy of Engineering, was interviewed a few days ago, and probably has the following interpretation:
First, some people have been impotent and produce antibodies, which should be the so-called asymptomatic infection. I have been infected, but because I have no symptoms, no feelings, and I have not done nucleic acid or antigens, I don't know.
Second, some people have been vaccinated, which has produced a strong protective effect, so there is no "yang". Some people also say that I am also vaccinated, so why am I yang? Vaccines behave differently on individual individual terms. Some people are fully vaccinated, the immune function in the body is relatively strong, the number of antibodies produced is large, enough to resist the virus, and may not be easy to be infected. Some people were also vaccinated, but the number of antibodies produced in the body was not enough or did not produce antibodies, so they were infected. But the effect of the vaccine is not to eliminate the virus, but to reduce critical illness to a certain extent, reduce the ability of the virus, and make your symptoms less serious. So this can't be like some people say that I was vaccinated and infected, so the vaccine is useless, this understanding is inaccurate.
Third, self-protection is good, not in contact with the source of infection, not yet infected. This category carries a potential risk of infection. Or for the second case, because the vaccine currently has enough antibodies in the body, but over time, the effect of the vaccine may decrease, and there is still a risk of late infection.
The situation of our baby is definitely not the third, it may be the first or second situation. Why some people are infected and some people are not easily infected; Some people are infected without any symptoms, and some people are infected but are in pain, and all kinds of discomfort gather. In a word: individual differences. This individual difference can be simply understood as a genetic difference.
Simply put, there are three types of people:
1 day to choose the lucky winner. The first and second cases above should be considered the lucky ones
2 days of the chosen "Tribulator". Those with particularly serious consequences caused by the new crown, the various symptoms are particularly obvious, serious, and uncomfortable.
3 Most ordinary people. Most ordinary people, about a week of illness, go through the process of a common cold patient. After that, the body returned to normal without causing serious consequences in other aspects of the body.
The people who have Yang in the whole family are most ordinary people, and the baby who has Yang in the whole family should be regarded as the chosen lucky.
Combined with himself he is a severe rhinitis patient, recently, a news that "allergic rhinitis patients are not easy to be infected with the new crown" has caused a heated discussion among everyone, and I unconsciously wondered if it is related to rhinitis.
allergic rhinitis
It is true that some people who are not infected trace the reason why they are not infected and think that nasal congestion caused by rhinitis provides them with "protection", but some people have suffered a very painful experience due to rhinitis. Are allergic people not easy to be infected with the new crown?
People with allergic rhinitis may have a little advantage. Allergic rhinitis, that is, overreaction.
Common allergens such as pollen and dust mites are found by immune cells after contact with the nasal mucosa, causing a crazy attack by the human immune system, in order to keep these substances out of the human body. However, the overreaction of the immune system can cause symptoms such as mucosal edema and rash, which can cause nasal congestion, runny nose, sneezing, and even difficulty breathing.
In the course of an allergic reaction, there is a type 2 immune reaction. It inhibits the expression level of ACE2 in nasal epithelial cells. Scientists have found that ACE2 is the receptor for the new coronavirus to infect human cells. Theoretically, ACE2 is inhibited, and the chance of new crown infection in the human body is correspondingly reduced, which may be the reason why allergic rhinitis patients have a slightly lower probability of infection with new crown.
Perhaps this is one of the reasons why the baby has no yang.
In the above, the whole family is yang, but the baby is not yang, which may be his individual differences and genetic reasons. So yang, or not yang, we are normal life, normal protective measures, there is no need to entangle too much, and there is no need to make people panic.
Of course, we still do a good job of self-protection measures, and we are the first responsible person. If you can not be yang, you should not take it lightly, especially if there are elderly people at home, for fear of causing other complications. If you really get hit, also face it with a positive attitude, you should rest and rest, you should take medicine and medicine, you should treat and treat, and don't have too much burden psychologically.
Peace and health to all! Tell me about the people around you who don't have yang?
