A common virus has completely paralyzed our lives. We have already been threatened by a virus of this type before. I also faced epidemics.
But for every new infection or seasonal flu, everything in the world has never stopped like this.
What is this coronavirus? Is there a puzzle in your biology that poses such a great threat to our bodies and lives?
‘The best of deception’
This virus can trick our body at the beginning of the infection.
The coronavirus can be present in our lungs and trachea. But our body’s immune system may think that everything is fine.
“This virus is really cool. It may have opened the virus factory in your nose, but you feel like your body is pretty good,” says Paul Lehner, a professor at the University of Cambridge.
When a virus is hijacked by our body, the cells of our body release a type of chemical called interference. These chemicals are actually a kind of warning for other parts of the body and the immune system.
“But coronaviruses have a great ability to stop this chemical warning,” says Professor Lehner.
“The virus does this so well that you never know you are really sick.”
“When you look at infected cells in the laboratory, you don’t realize they are infected. But when you examine them, they are full of viruses. The virus actually has deceptive power,” he said.
‘It hurts and escapes’
The day before the day we feel sick, the amount of virus in our body reaches its maximum. But it takes about a week longer for people to feel sick as if they were hospitalized.
“It’s actually a great evolutionary strategy for this virus: you’re not lying in bed after being infected, you’re dating, you’re having a blast,” says Professor Lehner.
So the virus behaves like a driver fleeing the scene after an accident. The virus escapes into someone else’s body before we recover or die.
To put it bluntly, the virus doesn’t really want to know if you’re dying, says Professor Lehner. It is a virus that escapes by hitting.
This is in stark contrast to the original SARS coronavirus from 2002. The SARS coronavirus was found to be more prevalent when people get sick.
‘It’s new, so our body is not ready’
Do you remember the last epidemic? In 2009, there was a widespread panic over H-1-N-1. Another name that was given was swine flu.
However, it was later discovered that it is actually not that deadly. Because older people already have some protection. The swine flu virus is like any other virus of the past.
People are infected with four more types of coronavirus, whose symptoms are similar to those of the common cold.
“It’s a new virus, so we didn’t have any resistance before,” said Tracy Hasell, a professor at the University of Manchester.
Professor Sarsell said that SARS-Covid-2 actually gives our body’s immune system a huge boost.
It is compared to smallpox or smallpox. Europeans brought the disease to America. For the people there, smallpox became a deadly disease.
In older people, it is very difficult to acquire a new immunity against a new virus because your body’s immune system is weak.
When the body learns to fight a new infection, many tests are needed. The body’s immune system makes many mistakes and then learns from those mistakes again.
But as we age, the different types of T cells that the body needs to fight decline. It is a very important ingredient in our immune system. Therefore, there are fewer T cells available to fight coronavirus in older people.
‘Strange and unexpected behavior’
Covid begins as a disease of the lungs. It also causes various strange and unusual events. Then it can affect the whole body.
Mauro Jiaccha, a professor at King’s College London, said that some of Kovid’s characteristics are quite unique. “It is different from any other conventional viral disease,” he says.
It not only kills lung cells, but also distorts them. One cell combines with another to form larger invalid cells, called syncytia. These large cells attach to the lungs.
Professor Jiaccha said that when infected with any other flu, the lungs heal on their own, recovering from the damage. But that does not happen with Kovid-19.
“It is actually a very strange infection,” he says.
Covid clotting also happens quite strangely. Beverly Hunt, a professor at King’s College London, says that the amount of blood-clotting chemicals in the body of many Kovid patients is 200, 300 or 400 percent higher than normal.
“Honestly, in my long career I have never seen a patient with such sticky blood.”
In many patients, the virus causes inflammation in the body, making the body’s immune system very sensitive and damaging the rest of the body.
‘Obesity’
If someone is physically obese, the covid is much more harmful to him. Obese people are at higher risk, may need intensive care, and may even die.
This is also quite unusual. The relationship of this virus with physical obesity has not been seen in the case of other viruses. Obese people do better with other lung diseases, says Sir Steven O’Reilly, a professor at the University of Cambridge.
The fats that accumulate in the body, especially in organs such as the liver, alter the metabolic function of the body. And if the coronavirus occurs in this condition, it leads to a worsening of the situation.
Obese people can have high levels of inflammation and protein levels, which can lead to blood clots.
