Report of Corona Virus reinsendotation October 5 at 10:11 p.m., following a series of research groups around the world
Research groups around the world have reported a series of cases in which people around the world have confirmed that they have been infected and recovered from the new coronavirus.
Experts say reinseration can occur, and “many patterns show that the more infections you have, the less severe the symptoms will be. I want them to take it without being overly afraid.”
In August, a research group at the University of Hong Kong announced that a 33-year-old man who had recovered from a new coronavirus in late March was confirmed to have been infected again after more than four months.
This is the first and second time in the world that two infections have been confirmed in the same person because the sequence of genes of the virus is different in part.
Since then, research groups around the world have reported that the reinthration has been confirmed, and in many cases the second is a mild symptom, but in many cases medical professionals in their 20s in India showed no symptoms, but the amount of the virus detected was higher than the first infection.
Meanwhile, a 25-year-old man in Nevada, USA, has been reported to have been hospitalized with pneumonia with heavier symptoms than the first infection.
The Dutch news agency, which is reporting these reports, said it had confirmed about 20 cases so far, and the scientific journal Nature published articles about reintheration.
It has not been elucidated why it is re-infected, but there are research reports that antibodies that prevent infection are reduced quickly after infection with the new coronavirus, and there is also a view that it may be infected many times, as is the common coronavirus that causes colds.
Yoshiharu Matsuura, president of the Japanese Society of Viral Studies and a professor at Osaka University, said, “It is more common for viruses that do not re-infect, and many patterns are that as infections continue, they do not cause severe symptoms. I want them to take it without being overly afraid.”
Virus researchers ‘sever or need more research’
As for the reinseed infection of the new coronavirus, researchers of the virus say that re-infection can occur, and that further research is needed to see if it can lead to severe infection.
The new coronavirus invades the human body through the mucous membranes of the upper gastrody, such as the nose and throat.
However, according to Professor Kazuhiko Katayama of Kitasato University, who is studying therapeutic drugs and vaccines for the new coronavirus, antibodies called “IgA”, which can form on the mucous membrane of the upper air path after infection and prevent infection at the entrance so to speak, where the virus enters, will decrease in a relatively short period of time, so it may be difficult to prevent reinvragnation.
Professor Katayama is planning to study how much IgA antibodies can be used in the mucous membranes of the upper air course if infected with the new coronavirus, and is also researching a new type of vaccine that sprays on the nose to prevent infection by encouraging antibodies to be made in mucous membranes such as the nose.
Professor Katayama said, “Reinseration is thought to occur on a daily basis. If IgA antibodies are made in the mucous membrane of the nose, the infection can be stopped before the virus increases, so we want to proceed with the development of vaccines.”
In addition, Professor Tetsuo Nakayama of Kitasato University, which specializes in virology, says that while there are many viruses that require mild or asyndoly ill in the case of re-infection, some of them become severely severe due to re-infection, and because they do not know which type of coronavirus is, it is necessary to look carefully.
Of these, the RS virus, which causes cold-like symptoms, can cause pneumonia and become severe in young children when infected, but according to a study conducted by Professor Nakayama and others, the amount of antibodies made when infected around the age of 1 is small, while repeated reinthoration increases the amount of antibodies and reduces symptoms accordingly.
On the other hand, in the case of dengue, which causes high fever and severe headaches, symptoms are often more severe after the second infection.
Prof. Nakayama says that in the case of the new coronavirus, there may already be many people who are unassayed without symptoms and are not aware of it, but it is not yet known what symptoms will be caused by reinsensucation, so it is necessary to look carefully.
Prof. Nakayama said, “In general, re-infection with the virus is often mild, but in the case of the new coronavirus, further research is needed to see if it will become severe. There is no need to worry too much, and general infection measures such as hand washing and disinfection should be thoroughly implemented.”
