For many, Covid-19 was a disease with short and mild symptoms. Those who have recovered must feel lucky. However, some people do not have that quick cure.
Many of them are suffering from chronic fatigue, severe pain and occasional difficulty breathing due to Kovid-19.
This condition is called 'long covid' or long-term covid. As a result, the lives of the victims have become miserable. It is often heard that some people get tired and exhausted after walking or working hard.
In the midst of the global epidemic, saving lives is paramount. But now there is growing concern among experts that some people have long-term negative health due to covid infection.
They still do not know the answers to many basic questions. Why some people are suffering from 'Long Covid' and whether they will all recover at some point - these answers are shrouded in uncertainty.
What is Long Covid?
Not all patients with chronic coronavirus have the same symptoms. As a result, there is no opportunity to define them on the basis of a list of symptoms. E.g. Two people with 'Long Covid' may experience completely different physical problems.
A symptom, however, is seen in almost everyone. That is; Exhaustion of the body due to extreme fatigue.
Besides, there are other symptoms; Shortness of breath, chronic cough, pain at the joints of the bones, tightness of the muscles, loss of sight or hearing in the ears, loss of sense of smell or taste, etc. In addition, it causes permanent damage to the heart, lungs, kidneys and intestines.
The disease of the body also causes stress in the mental state of the patient. As a result, they suffer from deep depression and anxiety. The ability to think clearly is also greatly reduced.
Simply put, 'Long Covid' is capable of completely ruining one's life.
"I feel so exhausted now that I've never felt this way before," said Jade Gray-Christie, one of the victims.
It takes a long time to recover from a serious illness after being admitted to the intensive care unit of a hospital - not just 'Long Covid'. Many people with moderate to severe coronary heart disease may later develop chronic intolerable physical problems.
"We have no doubt about the existence of Long Covid," said David Strain, a professor at the University of Exeter. He is providing medical services to such patients every day at his chronic disease treatment center.
According to some recent research data, one out of every 50 people infected with Covid-19 shows symptoms of Long Covid even 90 days after being infected.
Exactly how many people are being affected?
The largest hospital in the Italian capital, Rome, published a study on the health of 143 patients shortly after their release. The study found that at least 6 percent of patients had at least one symptom and more than half of them suffered from fatigue and exhaustion.
The study, however, has some limitations. Because, the study was done only on such patients who had to be hospitalized due to serious illness.
It is unknown at this time what he will do after leaving the post.
About 4 million people in the UK use a tracker app to detect the symptoms of Covid-19. According to the information found in the source of the app, even 30 days after the attack, 12 percent of the body had some or the other symptoms.
Moreover, according to some unpublished recent research data, the symptoms of 'Long Covid' can be seen even 90 days after the infection in one out of every 50 people infected with Covid-19.
Long covid is made from a terrible infection of the corona?
Most likely this is not happening.
A recent study in Dublin, Ireland, found that more than half of people still suffer from depression 10 weeks after coronary heart disease. And one-third of them could not return to work physically.
Physicians also failed to show any association of symptoms such as fatigue with a serious infection.
However, shortness of breath is just a symptom of 'Long Covid'.
Chris Brightling, a professor at the University of Leicester in the UK and lead researcher on a special project to cure post-infection covid patients, said those who develop pneumonia after exposure to the coronavirus are more likely to develop long covid later. This is because their lungs are severely damaged.
How does the virus cause long covid?
There are a lot of ideas, but no definite answer.Two people with ‘long covid’ may experience completely different physical problems. However, almost all of them show signs of exhaustion due to extreme fatigue.
Even when most parts of the body are free of infection, the virus can take refuge in isolated areas of the body. Maybe that's where he made the long covid in his body.
Tim Specter, a professor at King's College London, said: "If an infected person has long-term diarrhea, the virus must be in his stomach. For now, we're fighting Long Covid on that basis. "
Coronaviruses can directly infect different types of cells in the body and trigger a response in the body's immune system, which can also cause damage throughout the body.
One theoretical idea is that many people do not develop the normal immune system after covid infection, which later leads to long-term deterioration of the physical condition.
In this condition, the infection disrupts the normal functioning of various organs of the human body. In the case of the lungs which is now proven. Long-term problems with weakening the lungs have already been reported during the outbreak of two other Corona germs - SARS and MARS.
