Whether or not someone is infected with the coronavirus for the second time is a matter of debate, as well as worldwide research.
“The coronavirus is not likely to be infected a second time,” said the microbiologist. Bijan Kumar Shil The daily starWho said this on July 26. There he gave a detailed explanation. That statement did not receive much importance from our native doctors or experts. The controversy did not end there. Dr. Bijan stands firm in his position. He later told this reporter more than once. Explained.
On November 18 New York TimesAccording to the report, antibodies produced in the body of a person who has recovered from a coronavirus infection can be effective for years or even decades. If the antibody is effective, there is no risk of a second infection.
Published on November 20 according to a British study Reuters According to the report, those who have been infected with corona once are at risk of relapsing in at least six months.
“It’s definitely good news,” said David Erie, a professor at the University of Oxford’s Department of Nuffield Population Health, one of the leaders in British research. Most corona patients are not at risk of re-infection for at least a short period of time.
Dr. hosted in Singapore. Bijan Kumar Sheel on the phone this Sunday morning The daily starWho said: ‘The new form of the SARS virus from 2003 is the coronavirus from 2019. Which is 83 percent similar to the SARS virus. At that time we created the SARS virus in a laboratory in Singapore, inventing a detection kit. With which Singapore has successfully dealt with the SARS virus.
‘I don’t claim to be a great scientist. But I affirm that while the coronavirus is new to most experts, it is not new to me. The nature of the coronavirus, the speed-nature of the idea was already a little more than many. I know the virus from direct experience. From that research, knowledge and experience, I told them, it is unlikely that anyone who recovers from the coronavirus will be infected a second time, ” Dr. Bijan said.
In 2003, there was an extensive investigation into the SARS virus in Singapore. Dr. was part of the study. Bijan. The antibodies that the SARS virus produced in the body of those infected kept the immune system active for a long time.
A recent study in Singapore found that the antibody memory cell (T cell) that formed in the body of a person infected with the SARS virus in 2003 still exists and is effective in 2020. World-renowned scientific journal Nature The investigation report was released on July 15, ‘said Dr. Bijan.
Why there is no possibility of being attacked a second time, he said to explain. Bijan said: ‘With a very small number of AIDS patients and regular steroids, there is no possibility of a second Covid-19 infection. This is because antibodies in the body disappear after a certain period of time, just as it is true that memory cells that produce antibodies pass through the body before disappearing. If the coronavirus re-enters the body, it immediately produces those memory cell antibodies and inactivates or kills the virus.
However, there are still doubts about the second attack in the world, including Bangladesh. Every now and then you hear that such a person has been attacked a second time. Some have been attacked three or four times.
Some of the reasons for the news or suspicion said. Bijan said, “First of all, 30 percent of erroneous reports can usually come in the RT PCR test. When the first test was negative, you may have tested positive. Likewise, even if it is positive, it can be negative. It is cause for doubt or controversy. But I suppose the main reason is that coronavirus usually enters the body through the nose and mouth. The virus can re-enter the body of a person who has recovered from an infection. Coronavirus in the body does not mean that Covid-19 is positive. The virus enters through the nose and mouth when mixed with blood and shows signs of disease. If RT PCR is tested before mixing with blood, it will be positive. However, when mixed with blood, memory cells will produce antibodies to neutralize the virus. This means that the coronavirus cannot re-infect a person who has already been infected. Unless their immune system is damaged. somehow.
‘What we’ve been talking about since last July, America or Europe is talking about now. We were able to invent antibodies and antigen kits in the laboratory of the world’s first public health center because we had direct experience with the coronavirus. Unfortunately, it didn’t see the light of day. This pain will last my whole life, ‘said Dr. Bijan.
“Even if the coronavirus cannot infect a second time, the coronavirus that it carries will infect others,” he said. Bijan said: ‘The wearing of a mask is also mandatory for those who have recovered from the attack. Because it leaves many people at risk of infection. In other words, wearing a mask and following hygiene rules is the most effective way to prevent coronavirus.
