If I Get Coronavirus: Why do some people seem more ill than others? Will it return every winter? Will the vaccine cure this disease? Will people with an immunity certificate be able to return to work? How will we be able to compete with this virus for a long time?
Some of the most important questions being asked about the Coronavirus are directly related to our immune system. The problem is that we have very little information available about it.
If I Get Coronavirus, Can I Get It Again?
When will the Coronavirus harm you?
Our body’s immunity means our immune system protects us against any infection.
It has two parts. The first part is always ready.
As soon as it is revealed that an intruder has attacked the body, the first part quickly gets into action without delay.
It is also called natural immunity. When it works, some chemicals are secreted in the body.
This causes our body to heat up, and white blood cells (white blood cells) destroy the affected cells.
But this way of working the immune system has no direct relationship with the Coronavirus. It will not detect, and it will not protect you from Coronavirus.
Actually, you need a resistance that can adapt to the requirement. This process involves cells that produce specific antibodies. These antibodies work to stop the virus.
And T-cells start attacking cells infected with the virus. In the immune system, it is called ‘cellular response,’ that is, when a sick cell in the body defeats other cells. It takes time.
Research has shown that it takes about ten days for antibodies capable of targeting the Coronavirus. Those patients who are most ill develop the most powerful immune system.
If our ‘Adaptive Immune Response’ means the immunity that can adapt to the need is very powerful, then the infection can persist for more days, and it also protects us from future infections.
There are also some people who have mild symptoms of corona infection or none at all.
There is not much information currently available on whether such people will be able to develop sufficiently ‘Adaptive Immune Response.’
How long will immunity last?
The immune system also has a memory, just like ours. She remembers some infections well, but she forgets some infections habitually. Measles or measles is a disease that is remembered for a long time. Once done, immunity is given for a lifetime.
A weak version of measles is also given in the MMR vaccine.
However, there are many other diseases that our immune system often forgets. You must have noticed that in the winter season, children have a respiratory infection (pneumonia or lung infection) many times.
This Coronavirus named Sars-CoV-2 is not so old that it can be told how long will immunity persist against it? But the six viruses of the Corona family that infect humans can give some clues about this.
Four viruses of the Corona family show symptoms of the common cold, and their immunity does not last long. Research has revealed that some patients got infections again within a year.
But the common cold is usually with very mild symptoms. But the other two viruses of the Corona family are going to cause more trouble.
In the case of infection with severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), it was observed that antibodies developed after a few years.
Professor Paul Hunter of Medicine at the University of East Anglia says, “The question is not whether you will be immune or not, but how long the immunity will last.
It is certain that immunity is not a life-long thing. SARS In the case of the research done on antibodies, it was found that immunity will only last for one or two years. “
Even if you are not completely immune to any disease, it is possible that the infection may not be as severe as the second time.
Can anyone get an infection again?
There have been reports that after recovering from COVID-19, some people were re-infected with the Coronavirus within a short time.
On this, a section of scientists says that being re-infected is not surprising. It is a common natural phenomenon.
But another class is of the opinion that the Coronavirus hides somewhere before it can be reactivated in the body.
However, scientists agree that this can happen due to the testing problem. If the patient is told on the basis of incorrect testing that you are cured, then this can happen.
So far, it has not been intentionally re-infected with the Coronavirus to detect the immunity of a human being but with a pair of monkeys. These monkeys were infected twice. The first time to build up their resistance and the second time after three weeks.
These experiments happening at a limited level have shown that if they are re-infected so soon, the disease in them has No signs.
Am I Immune If I Have Antibodies?
There is no guarantee.
This is the reason why the World Health Organization is upset over issuing an immunity passport (or certificate) in some countries to get out of lockdown.
The reason behind the immunity passport is that if someone passes the antibodies test, then it is safe to go to work.
The idea of an immunity passport is particularly important for health workers working in extreme conditions.
But you will find that there is some amount of antibodies in all patients; yes, it is not equal in all.
Antibodies that protect cells from germs or infection may be effective in preventing the Coronavirus.
In the investigation of 175 patients recovering from COVID-19 in China, it was found that 30 percent of them had very little such antibodies.
Perhaps this is why the World Health Organization has said that ‘cellular immunity (the second part of the adaptive immune response system) is also very important for recovery.
Another reason is that the Coronavirus cannot spoil you because of your antibodies, but it also does not mean that you cannot become a carrier of the virus and infect other people.
Why does immunity matter so much?
There is no doubt that it always matters for personal health reasons.
Whether or not you will be infected with the Coronavirus, and how many times it will be, are the questions that bother many people.
Your immunity determines to what extent this virus is dangerous for you.
If people have immunity, even if there are deficiencies in it, but it makes any disease less dangerous for you.
If it is clear who can be infected, and who can infect, it will help to waive the lockdown. For this, immunity has to be understood.
If it is very difficult to develop immunity for a long time, then believe that preparing a vaccine for it will be equally challenging.
It is possible that the way of using the vaccine has to be changed. It can be for a lifetime or like a flu shot for a year.
Whether immunity meets the vaccine or in some other way, but from this, we will know to what extent we will be able to stop the Coronavirus from spreading.
There are many other big questions that do not have answers.
