Chapter 992 Virus (Leader Ricky Zou Jiageng 2)

Dai Yuan stood up obediently, followed Jiang Yanhai, and walked to the door that was shining with silver-gray light. All the people who were transporting supplies stopped temporarily and looked at this side.

Both Jiang Yanhai and she could see the people in protective suits working inside.

"Yuanyuan, try it, can you do this?" Jiang Yanhai stretched out his hand tentatively, as if reaching out in the air, directly through the portal and into the base.

Dai Yuan was not afraid at all, she saw Jiang Yanhai and the others came out of this door, she also stretched out her hand out of curiosity, trying to reach in, but when she reached out to the plane of the door, the air was filled with As if there was an invisible barrier, it directly blocked her dirty little hands.

"No." Dai Yuan shook her head, and then said softly, "Brother, that should be your world, I can't get through it, it's hard here."

While speaking, Dai Yuan stretched out her hand to caress in front of her, as if her hand touched an invisible barrier, Jiang Yanhai simply grabbed her hand, and then tentatively stretched inside.

The result was still the same, her hand was blocked, but Jiang Yanhai's hand didn't feel anything at all.

Many people on both sides of the portal saw this scene, and the two video recording devices that had been set up inside the portal captured this scene.

Seeing this scene, Jiang Yanhai narrowed his eyes slightly. This thing...is interesting, why can the Red Crazy Wolf get through, but Dai Yuan and the others can't.

"It's okay, the food should be ready, let's go, let's go eat." Jiang Yanhai stood up with a smile, and walked over there holding Dai Yuan's hand.

While walking, Jiang Yanhai re-scanned Dai Yuan's body carefully with the battlefield medical scanning program, according to the conclusion given by Er Dan.

She has all the common viruses and some bacteria, microbes, etc. all on her body.

The human body itself is a huge melting pot of viruses. For example, the once famous SARS is a coronavirus, and the coronavirus is a single-stranded virus, which is very easy to mutate.

In fact, the evolution direction of viruses is always towards low harm and high infectivity, because viruses are also living things, and their purpose is to survive, not to kill.

If the host is killed, wouldn't it die? Although it is said that coronaviruses like SARS and Middle East Respiratory Syndrome have a high fatality rate, it is because these things themselves are not human viruses, but the most common influenza virus in humans.

In fact, whatever cold medicine you drink never actually kills the flu virus, it's your immune system that does.

Just like SARS, when you put it on, it is also called pneumonia. Pneumonia is the inflammation of the lungs. When you take an X-ray at this time, the lungs are white. Why are the lungs white? , It is because the virus infects your lung cells. After the cells are infected, it instinctively wants to eliminate the virus.

But what will it do when it finds that it cannot eliminate the virus? It will send some virus fragments to the surface of the cell membrane, telling other cells that I am infected, and quickly ask the boss to kill me.

Who is the boss? That is, our body's own immune cells, such as white blood cells, will deal with the virus after the boss comes over, and this process will generate an immune response.

A weak immune response, in fact, does not have any body surface reaction for humans. We absorb a large amount of viruses every day. After the immune response is triggered, we may not all speak.

Inflammation is a serious immune reaction. It appears red. Why is it red? Because the blood flow speed becomes faster and the blood vessels expand during the immune process, because the blood needs to transport more white blood cells to this part. The blood vessels dilate because the immune system needs more white blood cells to run into your interstitial fluid.

Then let the white blood cells kill the virus, and the body fluid increases, accompanied by swelling.

So is inflammation a good thing? No, excessive inflammation is harmful to the human body.

In the process of human inflammation, it will cause a severe thing called cytokine storm, because the human body has many kinds of immune cells, and these immune cells will secrete a factor that has many functions, such as white blood cells .

The factors it secretes can promote the increase of white blood cells and increase the number of white blood cells, commonly known as building soldiers!

But when the white blood cells increase, there will be a situation, that is, an indiscriminate attack. It will kill the cells infected by the virus, but when it increases, it will directly kill all the cells in your area. You guys A piece of cells will not survive.

At the same time, because a large amount of body fluid accumulates in the lungs, it will cause difficulty in breathing in the lungs, and finally people will suffocate to death.

The cytokine storm or excessive immune response is the direct cause of death, and of course the root cause is viral infection.

Therefore, when an excessive immune response occurs, we will use some drug responses to suppress this immune response and let the white blood cells work slowly instead of drying all the cells to death all at once.

As for the special drug to kill the virus, it’s not that we don’t develop it, but that this single-stranded virus, which doesn’t even have a cell membrane, is too easy to mutate. If a drug is developed, it will mutate soon, and the drug will lose its effect.

This is also the reason why the flu virus has never been eradicated. It has mutated for an unknown number of generations. Cold medicines suppress the virus and allow the body's own immune system to work.

So don't believe that any medicine can kill viruses and the like, the most important thing is to prevent and enhance your own immunity. Healthy life and rest, healthy diet, proper exercise, when you stay at home, you have nothing to do on the treadmill. It's good to do yoga.

"After scanning and comparative analysis, Dai Yuan's body immunity is stronger than that of people in the real world, and she does not carry deadly or unknown viruses." Erdan gave the latest analysis.

Jiang Yanhai had some surprises, didn't he say something right? All modern people who have traveled through history with their physical bodies, unless they are self-sterilized, otherwise, you alone are more terrifying than the typhoid Mary in history, and more people died from your infection than those who died in World War I and World War II.

The viruses carried by modern people and the changes in the environment have led to the fact that the immunity of modern people is actually much stronger than that of ancient people. Many viruses carried by modern people that they can't feel at all can infect and kill a lot of people in ancient times.
