is also positive, but why do the symptoms vary? Are some lucky people really chosen to be workers?
Some people even joked that the symptoms were mild when going to work, but the symptoms would be worse when resting at home. After the virus enters the human body, how does the immune system work?
The new coronavirus is a typical RNA virus. From a macro perspective, it only consists of the protein, shell and a piece of RNA.
In fact, many people do not know that the new coronavirus itself does not have the ability to move and reproduce, but relies heavily on the resources of the host.
After the new coronavirus enters the human body, it will first lurk in the oral mucosa and nasal cavity. The highly camouflaged protein shell becomes the key for it to enter cells.
Under normal circumstances, white blood cells will constantly patrol and clean up harmful substances that are ready to enter the cells. Miraculously, the protein shell of the new coronavirus can cause white blood cells to misjudge it as a friendly force, thus evading disaster. After receiving the instruction, the
motor protein will carry the new coronavirus into the cell. Once the time is right, the new coronavirus protein shell will rupture, and the released RNA will invade the host and reproduce in large quantities.
However, the invading new coronavirus will also quickly activate the body’s immune system.
After becoming positive, the symptoms vary from mild to severe. Is it really related to the strength of the virus strain?
If only a small amount of the new coronavirus invades, the white blood cells and antibodies produced inside the human body will quickly eliminate them. If there are too many viruses for white blood cells to win over, they quickly synthesize proteins called cytokines. The protein
warns the body of an incoming virus and calls on the entire immune system for help.
At this time, the body's blood flow rate will speed up and more white blood cells will be concentrated to destroy the virus.
At the same time, the body will generate heat in order to produce more immune cells . The protein in the muscles decomposes , and the lactic acid produced will make the body feel sore.
In addition, the process of immune cells breaking through the blood vessel wall and eliminating the virus may also compress the nerve endings , causing a sore throat like "swallowing a razor blade".
The immune system fights against the new coronavirus. In addition to the number and strength of the virus, the symptoms the human body feels depend more on its own immunity.
If the immunity is strong, the virus can be eliminated quickly and the symptoms will be mild; if the immunity is weak, the body needs to mobilize more resources, and the symptoms will be more obvious.
There are more and more people with Xiaoyang. Which people are less likely to be infected?
I don’t know if you have noticed that some of the Yang people around me love fitness and are in great health, but some people look weak and weak, but they can never be infected.
Some people have even found that those who smoke and drink seem to have a lower probability of infection. Who are not easily infected?
Research shows that the new coronavirus has universal susceptibility, which means that under the same conditions, everyone has a high probability of being infected.
The key to the problem is that even if some people are infected, they will not show obvious symptoms, while some people will have high fever, aches and other symptoms.
Therefore, people with stronger immunity can often eliminate the virus faster, even without being aware of it themselves.
It is worth mentioning that people with strong bodies do not have stronger immune capabilities. There are great differences between human individuals, including the response speed of the immune system and the ability to eliminate viruses.
As ordinary people, the most important thing to do when facing a virus is to maintain adequate rest time to keep the immune system in a better state.
At the same time, take protective measures as much as possible to reduce the number of virus intrusions, so that you can better protect yourself.
Are there people around you who are never infected? What characteristics do they have?
