Covid-19: Coronavirus has become fatal due to these five reasons

172

Coronavirus has badly affected people all over the world. Even before, humans were at risk of viruses. Even before the epidemic had spread, the world did not have to stop like this to deal with every new infection or flu.


So what is there in this coronavirus? What is there in its biology that becomes dangerous to our body and life?


Expert in cheating

In the initial stages of infection, the coronavirus is able to cheat your body.


The coronavirus is extensively present in our lungs and respiratory system, but our immune system feels that everything is fine.

Professor Paul Lehner at the University of Cambridge says, "This is an amazing virus. It builds a virus factory in your nose and makes you feel like you're fine."

Our body's cells release chemicals called interferon. When a virus takes over these chemicals, then our body and immune system start getting warnings about the presence of the virus.

However, the coronavirus has an 'amazing ability' to stop this warning. Professor Lehner says, "The virus does this job so well that you don't even know you're sick."

He says that when you see the infected cells in the lab, they do not appear to be infected at all, but when you do a test, it shows that there is a lot of virus in them.

Hit and run a virus

When the virus present in our body reaches the 'load peak', then we fall ill and the symptoms start appearing.

In such a situation, the virus is present in the body even without the symptoms appearing and can spread from one person to another.

It takes about a week for the viral load to reach the patient's hospitalization.

Professor Lehner says, "This is a great way of developing yourself. It does not immediately bring the patient to the hospital but makes him feel fine, allows him to move out of the rest so that the virus can spread further. ”

Therefore, the coronavirus is like a driver who runs away immediately after an accident. The virus also goes into another person immediately before an infected person recovers or dies.

This is a big difference between the original SARS-Corona virus of 2002 and the existing Coronavirus.

The original SARS-Corona virus had the highest risk of infection after people became ill, which made them easier to isolate.

Stranger virus to the body

Remember the last pandemic? In 2009, there was a lot of fear among people about H1N1.

However, it did not turn out to be as deadly as it was being expressed.

The reason for this was that the ability to fight this virus was already present in the elderly to some extent. Because a similar virus had spread earlier. There are four more human coronaviruses that have cold-like symptoms.

Professor Tracy Hassall from the University of Manchester says, "This is a new type of virus so people don't already have an immunity to fight it." Its new effects prove to be a setback for your immune system. "

This can be compared to smallpox in Europe. Even for that, people did not already have immunity, which led to very fatal results.

Getting a new immunity to fight a virus is a big problem for the elderly because their immune system is weakened.

The immune system has to undergo many changes to fight a new virus.

Like we adopt many ways to solve a new problem. Some of these methods are successful, some fail and some have to be changed.

Similarly, the immune system also works. However, T-cells are considered to be an important part of the training system at an early age. Therefore, it is difficult to form new immunity.

Full body access

The coronavirus spreads throughout the body, affecting the lungs.

Professor Maro Gaca at King's College London says that many aspects of Kovid are very unique. "It is different from other viral diseases." He says that it not only kills the cells present in the lungs but also spoils them. The damaged cells connect to the healthy cells around them and make them ill and take a big form.

Professor Gala says that after the flu your lungs can be completely healthy again but this is not the case with Kovid. This is a strange kind of infection.

In this, blood clots also begin to accumulate in the body. Many times doctors also find it difficult to find veins in patients due to clotting.

Professor Beverley Hunt at King's College London says that blood clotting chemicals have been found to be "200, 300, 400 times higher" than normal in some Kovid patients.

He told Inside Health, "I want to say with honesty that in my career, I had never seen such thick blooded patients before."

The reason behind the coronavirus having an effect on the whole body is the ACE2 receptor in the body through which the virus infects the cells.

The ACE2 receptor is a type of protein found throughout the body, including blood cells, lungs, liver, and kidneys. Hence the coronavirus reaches every organ.
