As the upsurge of infection with the new crown virus across the country faded, most people returned to normal life, and most people were infected with the new crown virus after the country just adopted a comprehensive liberalization policy.
But some people will also have the chosen lucky ones around them, although most of the people around them are infected, but they are still not defeated, making others envious.
Some people feel that people without yang seem to have innate immunity, and there is even a saying that people without yang have more outstanding genes, is this true in the end?
01
Are people who have not "impotent" genes more outstanding? The results of the study are worth noting
According to foreign studies, during the new crown epidemic, people who carry the HLA-B*46:01 allele have a 63% probability of infection than people who do not carry this gene.
Because people who carry this gene are particularly susceptible to infection and severe symptoms, other studies have shown that the susceptibility of the new coronavirus is closely related to T cells and white blood cells.
Because different types of white blood cell surface antigens have different ability to bind to viruses, some white blood cells can quickly recognize and clear viruses to avoid virus invasion.
According to the results of the study, some people may have genes that are not easily infected, while some people may have genes that are easily infected, and Academician Zhang Boli said that the number of carriers of these genes is small because most people do not have susceptibility genes and anti-sensitivity genes.
Although there are few people around who have not been impotent, they are of great help to the research of drugs and future vaccines, and also provide new ideas for epidemic prevention and control.
Among the people who have not been positive, there may be people who have been infected, but they have not shown obvious symptoms and have not undergone nucleic acid testing.

People who have not yet had yang may be related to these factors
Good living habits
Usually, we should pay attention to a balanced diet, ensure adequate nutrition, such as high-quality protein, high-quality carbs, you can eat more vegetables or fruits, not picky eaters, eat less junk food or drinks, and make nutritional reserves for the body.
Some people may develop the habit of regular exercise and adhere to a regular schedule, so they may not have yang, or there are no symptoms after impotence.
Protect yourself
Usually, you should pay attention to personal protection, you should wear N95 masks in time when you go out, talk to others as little as possible, and usually carry alcohol with you, and disinfect at any time.
When you get home, you should spray your hands, clothes, shoes or belongings with you before changing your home clothes, especially when receiving couriers, and disinfect them with alcohol.
vaccination
Vaccination produces antibodies in the body, which can also reduce the infection rate, and vaccination not only prevents viral infections, but also reduces the risk of severe disease or death. Although some people are also positive after vaccination, it does not mean that the vaccine is ineffective, because it is related to personal constitution and environment.
Yang Guo does not know it
Some people have been impotent, but the symptoms are particularly mild and may not know it, but most people will have fever, sore throat, body aches, cough and other problems after infection.
However, it is not excluded that some people have been infected but do not have symptoms because the viral load is relatively low and the virus has completely disappeared over time.
03
Will people who have not yet been impotent be more likely to be infected with the new strain than "Yangkang" patients?
The severity of the patient's condition after infection is related to the pathogenicity of the virus, because the pathogenicity of the Omicron variant is almost the same.
If you are infected with Omicron, the possibility of reinfection within 3~6 months is very low, but if you encounter a strain with strong immune evasion ability, the recovered person may also be re-infected.
If the Yangkang person is infected again, the symptoms may be milder than the first time, and if the nucleic acid test result is always negative, it is also necessary to be vaccinated in time, which can prevent severe disease or the risk of death.
