Important revelation from health experts from Corona
People who recover from a new type of corona virus, Covid 19, can fight the disease for months, and the virus is unlikely to reactivate.
A medical study in the United States found that people with mild to severe Covid 19 still have immune cells that produce antibodies that neutralize the virus, even after months of recovery.
According to a foreign news agency, the study by the Washington University School of Medicine showed that the continuity of these immune cells could potentially last a lifetime, which will continue to make antibodies.
Research has shown that people with mild to moderate coronary heart disease can have long-term protection and are less likely to relapse.
The researchers said that last year there were reports that the levels of antibodies produced by cod in sick people decreased rapidly, after which it was said that people’s immunity does not last long.
He said that this was a misconception taken from the data, it is common for the level of antibodies to decrease after the disease but it does not reach zero level.
“We discovered antibody-producing cells 11 months after the first symptom in people who beat the code, these cells are present throughout life and make antibodies, which is solid evidence of long-term immunity,” he said. Get it
Research has shown that immune cells that make antibodies to a viral infection multiply rapidly and spread throughout the bloodstream.
Antibody levels are greatly increased, most of these cells die when the disease is over, and the level of antibodies in the blood decreases.
According to research, some of these cells are transferred to the bone marrow and stay there, releasing small amounts of antibodies into the bloodstream to protect the body from another virus attack.
The study looked at whether code 19 provides long-term antibody protection, and how long the average person is protected from the virus.
For this purpose, 77 people who had been infected with Code 19 were recruited and their blood samples were obtained several times.
The first samples were taken one month after the initial illness and then at three-month intervals. In most of the people involved in the study, code 19 was not very severe and only 6 had to be hospitalized.
The researchers took bone marrow samples from 18 people who had either become more ill or had had an initial illness nine months later. For comparison, the researchers also obtained the bone marrow of 11 people who had never encountered Code 19.
Antibodies levels in people exposed to code 19 dropped sharply a few months after recovery, but some antibodies were still present 11 months after the onset of the disease.
Fifteen people infected with COD 19 had antibody-producing cells in their bone marrow, and these cells were present in the body of those who re-specified the bone marrow 4 months later.
However, these cells could not be detected in the bone marrow of any person protected from cod.
The researchers said that people with a mild illness from COD 19 get rid of the virus 2 to 3 weeks after the onset of the disease, so they do not have a dynamic immune response 7 or 11 months after the onset of the disease.
These cells do not divide, but live in the bone marrow and make antibodies, something they have been doing since recovery and possibly indefinitely.
The study suggests that patients with COD who do not show symptoms may also have long-term protection, but they will be able to say more after further research.
According to experts, edema plays an important role in people suffering from severe severity of the disease and too much edema can lead to defects in the immune response, but on the other hand, most people are very ill because their body. The amount of virus is very high and the presence of too many viruses can lead to a strong immune response.
“While not everything is clear yet, we need to research people with moderate to severe severity to see how well they are protected from re-infection,” he said.
