(Washington / London Composite Electric) A number of studies show that the symptoms caused by Omikon's symptoms than other crown diseases may be slightly more infected because of this variable virus.The respiratory tract has less impact on the lungs.
Japan and the United States researchers in mice and hamsters showed that the lungs of Omikon's experimental mouse were lung, and their weight dropped less, and the deaths were lower.In contrast, the experimental mouse in the early variant of the infection will experience symptoms such as lung scarring and severe breathing difficulties.
The joint author of the report, Dimmond, and colleagues of the University of Washington University, and colleagues found that the level of Omikon virus in the hamster nasal cavity is consistent with the experimental mouse of the early variant of the virus infection, but the virus level in the lungs is the other variable strains.One tenth or less.
Researchers at the University of Hong Kong analyzed some tissues taken out of the human respiratory tract during the operation, and the results were drawn with similar conclusions.They found in 12 lung samples that Omikon's growth rate was slower than Delta and other variable strains.
Researchers also analyzed the tissue of the human bronchial infection, and found that after two days of infection, Omikon's growth rate in bronchial cells was faster than Delta or primitive strains.
Gubapa, a virusist at the University of Cambridge, revealed that the recent research data of the research team may be able to explain slowly from the perspective of the molecular perspective.
He pointed out that many cells in the lungs will carry a protein called TMPRSS2 on the surface, and this protein will inadvertently assist the virus into the cells.
The research team of Guba found that this protein could not grab Omikon well, making Omikon not as good as Delta in infection.
Because the cells in the upper respiratory tract often do not carry this protein, this may explain why Omikon will appear more often there.
Gubuta speculated that Omikon may evolve into viruses that are growing rapidly in throat and nasal cavity, which is more likely to be expelled from the surrounding air in the form of tiny water droplets to find the new host.
Researchers will start further research, such as experiments on monkeys, or checking the respiratory tract of Omikon patients.If the results of the study are still consistent with earlier after review, this may explain why the risk of infection with the infected Omikon is low.
Analysis of the cases of more than 1 million Omikon and Delta cases showed that the hospitalization risk caused by Omikon was about one -third of Delta.
