Is it possible that some people are naturally immune to New Crown virus?
It is well known that the rate of infection and transmission of New Corona virus is very strong, and to a large extent, healthy people are likely to be infected if they come into contact with people with New Corona virus. New Crown.
Greek flight attendant Angeliki Kaoukaki is one of these "Chosen Ones. She had contact with a New Corona virus-positive flight crew member when the epidemic first began, but was not infected.
Later, her partner was diagnosed with severe Neoplasia and they were isolated in a single room apartment for 14 days, but her test results were still negative.
Later, after her partner had recovered, she was unfortunately struck again, and after several days of isolation together, Kaoukaki was still not sick.
Is it true that people are naturally immune to the new corona virus?
To find the answer, immunologist Evangelos Andreakos searched for specific genetic variants and eventually discovered that as many as 5,000 people had similar experiences to Kaoukaki.
In response, scientists speculate that if some people are repeatedly exposed to the new corona virus but do not become infected, this means they may carry a resistant mutation that can resist the virus.
First, why do some people not get New Crown?
A company called Open Orphan conducted a study last year in which 36 healthy young people were exposed to the New Corona virus and then lived alone in a hospital room for 17 days.
And one of the volunteers, named Penn, was unharmed during that time, no matter what patients he came in contact with.
In addition, a study published in the Journal of the American Medical Association (JAMA) in 2020 found that there are 2 groups of people with relatively low rates of New Corona virus infection.
One, children, in less than 2% of confirmed cases, because children have lower levels of ACE2 gene expression than adults, and this level of gene expression may be related to our susceptibility to COVID-19.
The second is smokers who quit smoking, which was found to have high ACE2 levels in the lungs of smokers and to be more susceptible to severe neocon, while quitting smoking may reduce the risk of severe neocon infection.
Similarly, previous studies at Imperial College London have shown that some people do not get the virus even when exposed to SARS-CoV-2, possibly because the person has previously been infected with other types of corona viruses, and cross-reactive T cells produced by induction can protect the body from infection with new corona viruses.
For example, among the viruses that cause colds in humans, some of them are corona viruses, which may mean that colds help reduce new corona virus infections.
But no matter what, the answer to why this part of the "Chosen One" will not be infected with new-corona virus is still not found, and the future still needs to be explored.
Second, those who have been infected with New Crown, what happened to them?
There is nothing more worrying than the sequelae of neostriatal infection, how long will the sequelae last? Is it possible to recover?
Recently, Nature Communications published a study conducted by Imperial College London, which studied a random sample of more than 600,000 people.
The results found that: 3 months after the first symptom appeared, some people still had 1 symptom appear, including fatigue, chest pain, chest tightness, fever, palpitations, malfunction of smell, malfunction of taste, difficulty in breathing, skin rash, joint pain or swelling.
As you can see, infection with New Crown can still have a significant impact on patients.
And in order to reduce the risk of infection, as well as the clinical severity, it is recommended that people actively pursue vaccination against New Crown.
A study published in the CDC Weekly Report (English) showed that vaccination against New Crown reduces the risk of pneumonia by 50%-70% when infected with the delta variant strain, and if a booster is administered, that effect is even more pronounced, with an 86% reduction in risk.
Also, the risk of serious illness in adults is reduced by 70%-80% after vaccination, and the risk of serious illness is reduced by 91%-98% if a booster vaccination is given.
III. How to prevent new crown? Immunity is the "best doctor"
Professor Zhang Wenhong, Director of Infection Department, Huashan Hospital, Fudan University, once said, "Immunity is the best medicine to fight and prevent diseases." This also applies to the new crown protection.
Infectious or infectious diseases, such as the usual mentioned, in fact, essentially refers to the pathogenic microorganisms into the body, the body is not enough to fight and "sick", the new crown is a typical example.
The immunity of the body plays an important role in getting rid of the new corona virus, and if the immunity is strong, the chance of "defeating" the new corona virus will be greater.
Therefore, to prevent the new crown, we should also pay attention to protect their immunity, especially lack of sleep, do not like to walk, do not like to drink water, second-hand smoke, abuse of antibiotics, couples with a cold relationship and other people, more likely to lack of immunity.
If there is easy fatigue, poor spirit, the number of colds becomes more frequent, wound healing slower, etc., be alert to the decline of immunity, timely ways to enhance immunity, so as to avoid the disease to find.
That how to effectively improve the body's immunity, there are 3 points of advice may wish to listen to.
1, supplement protein
Protein is a large material basis for the formation of antibodies, so you want to enhance immunity, it is natural, it is recommended that you can usually eat more eggs, milk, soy, fish, shrimp, lean meat and other protein-rich food, pay attention to do a reasonable mix.
2, adhere to a healthy lifestyle
Including stay away from smoking and alcohol, eat more fresh fruits and vegetables, less pickled, fried, processed food; three regular meals, balanced diet, do not stay up late, etc., to develop a good lifestyle habits, to protect the body's immunity is also an important part.
3, actively participate in physical exercise
Regularly adhere to exercise can promote metabolism, enhance immunity and strengthen physical fitness. The best sports exercise to improve the body's immunity, it is recommended that 1 week at least about 5 times of moderate intensity exercise, a 30 to 45 minutes, adhere to more than 4 weeks.
Conclusion: Some people do have immunity to the new crown virus, but this is only a small number of people, so for the general public, the good protection should still be done, do not take it lightly, so as to avoid the new crown on our health.
