It has been nearly 3 years since the new coronavirus swept the world. During this process, some people unfortunately became "Wang Chongyang", while others were like "Chosen Sons" with their own aura of protagonists, living with "Yang people" without being infected.
Have you joined the "Yang Circle"?
has this phenomenon. Could it be that the transmissibility of virus has become weaker? But if the virus is really getting weaker, why are so many people still infected? Has the
virus become less transmissible?
As a thing that cannot express life phenomena on its own, a virus is neither a living thing nor a non-living thing. For many years, the identity of the virus has been difficult to define. Most of the time, people have regarded it as a special existence with the goal of "replication and reproduction."
Viruses basically reproduce through replication
Not only were they born very early, they also have many types. Different viruses will cause different symptoms after invading the human body. Before tools can be used to observe their specific forms, people generally judge which virus has been invaded based on physical symptoms.
Because viruses have a very special survival mechanism and are difficult to completely eliminate, once they appear, they always turn the human world upside down. So, which virus do you think is the most powerful? What characteristics does a virus need to have to become a "TOP1" existence?
Which virus do you think is the most powerful?
Everyone may have different opinions on who is the king of viruses. Some people think that the "lethality rate" of viruses and is the best proof of their strength, so those that "kill everyone" as soon as they appear, such as Ebola virus , are the champions.
Some people also think that the scale of infection of virus can only prove its strength. For example, for the new coronavirus we are currently facing, although its fatality rate is not as high as that of Ebola virus, its contagiousness and invasion degree are significantly higher.
The new coronavirus is more contagious and more invasive.
In fact, the first task of viruses after their birth is to "replicate and reproduce", and it is difficult for them to complete this goal after leaving the host. Therefore, the real "poison king" of will eventually reduce its virulence and impact on humans, and instead increase the contagiousness of .
This means that the more contagious the virus, the more successful it will be. The new coronavirus we are facing now is evolving in this direction. Judging from its toxicity, it is no longer as good as it used to be, and its fatality rate has also dropped significantly. But after sacrificing this aspect, it became more contagious.
Sometimes, healthy people can become infected just by passing by an infected person. From this point of view alone, the transmissibility of the virus has not become weaker, but has a tendency to become stronger.
Anyone who passes by an infected person may be infected.
In this case, why can some people not be infected after living with "yang people" day and night? Could it be that the virus really doesn’t work on some people?
Why was he not infected when he came into contact with a "positive person"?
People have previously shared their experiences after being infected with the new coronavirus on social platforms such as Weibo . Judging from these diverse experiences, there are obvious differences in the "symptoms" caused by the virus when it meets people with different physiques.
For example, some people will have a fever for many days, while some people will have no obvious symptoms after having a low-grade fever for two days. Among all the people, the most outstanding ones should be those who stay in the "yang group" but have never been infected. Why are they so special?
People infected with COVID-19 may show different symptoms
Generally speaking, there are three main reasons for this situation. The first is that one's own immunity is strong, the second is proper protection, and the third is that the person has antibodies.
First of all, in terms of relatively strong immunity, it is always more difficult for viruses to conquer the bodies of such people.Therefore, some people with relatively strong immunity are considered to be "gifted". Before they realize it, their own immunity has already killed all the viruses, and they will naturally not be infected.
Everyone’s immunity is different.
The second is proper protection. After the transmission method of the new coronavirus is clarified, some people will live "fully armed" next to "yang people". Not only will they physically isolate themselves from each other, but they will also take protective measures when they have to meet.
In this case, even if he shuttles among the "yang groups", he can still "pass among hundreds of flowers without touching a single leaf". After all, the infectivity of the virus will be greatly reduced after leaving the host, so even if there are some residues in the environment, it will be difficult to cause human infection.
People in the crowd should wear masks and take good protection.
The last point is that they have antibodies. Some people who live with "positive" people may have already passed the "positive" status. In this case, if comes into contact with the same strain of virus, its own immune system will be able to detect it in advance, and its own antibodies will also kill the virus.
In addition, whether is infected is also closely related to the virulence and virus load of the strain that the "positive person" is infected with . If the virus load is not high, you may not be infected if you take good protection.
The toxicity of different strains is also different.
It is worth mentioning that a research team has previously conducted a survey specifically on certain "people who are less susceptible to infection" and found that there are some people in the world who are really not susceptible to the new coronavirus.
"The Chosen Ones" are just a few
According to the data, the research team of West China Hospital in Sichuan conducted an in-depth study of infection cases and found that some patients with allergic rhinitis seemed not to be susceptible to the new coronavirus.

In order to prove that this conclusion is true and credible, they also compiled the relevant results of the research into a paper and published it in the famous journal "The Journal of Allergy and Clinical Immunology: In Practice". If you are interested, you can read the original article.
In the experiment, they investigated the physical health of different sick people based on relevant data from the British biobank . Finally, it was discovered that people suffering from allergic rhinitis seem to be born with a different "immune effect" against the new coronavirus than ordinary people. They speculated that this may be closely related to the human cell surface receptor ACE2.

Of course, this research result does not mean that this kind of people have a "gold medal to avoid death". It can only be said that their probability of being infected is lower than that of ordinary people. In addition, foreign countries have also found some people whose blood has a strong ability to dilute the new coronavirus .
But no matter what, these people are in the minority after all. Therefore, when facing the new coronavirus, we should not expect to be the legendary "chosen one", but should take good protection to prevent the virus from quietly invading our bodies. Especially after you know that the person you live with is "yang", you should keep a certain distance from them to avoid being infected. If you really can’t stay away from them, wear a mask, disinfect them at all times, and avoid direct contact or unprotected conversations with them.
Always do disinfection at home
