Masks, social distancing, hand hygiene and other anti-Covid measures may have eliminated two influenza virus strains, namely the H3N2 clade (influenza A virus) and the B/Yamagata strain (influenza virus). In fact, these two strains have not been detected by the laboratory since March 2020. If confirmed, this is good news, especially for vaccine development.
Expired tree stump of virus responsible forSeasonal flu It may be extinguished due to measures taken to combat the disease Pandemic of Coronavirus disease. It has been known from epidemiological surveys conducted in different countries that the influenza epidemic has actually been cancelled due to the continued use of influenza viruses. maskFrom Social isolation, From the constant Hand hygiene (With soap and water and hydroalcoholic gel) and all other limit Object Coronavirus SARS-CoV-2, But the disappearance of the entire virus strain from the “radar” is a particularly important novelty.In fact, if proven, this will lead to better accuracy vaccine We are preventing influenza every year and we were able to eliminate two possible targets from the list.
Announce Potential disappearance Two strains of influenza virus-especiallyH3N2 (Called 3c3) and the line B/ Yamagata -Professor Trevor Bedford, a viral evolution expert and computational biologist at the Fred Hutchinson Cancer Research Center in Seattle. the scientist, STAT interview Together with Florian Krammer, a virologist at the Mount Sinai School of Medicine in Manhattan, he said that it is very likely to disappear, and even though the world is “big”, these two strains may still be seen everywhere. They may not be detected at all due to the disruption of the health system due to the ongoing pandemic. To be sure, these two strains did not appear in the international virology database.
In short, there is a system Monitor In many countries it is monitored which strains of influenza viruses are circulating; this is extremely valuable information (also) for the development of vaccines each year, based on predictions that will lead to the main lineage of the season. Influenza viruses are numerous and extremely variable, and are actually divided into four main types (A kind, B, C electronic D) Only the first of these is usually related to flu season, and only the first can be triggered Pandemic. Vaccine Three price/four price Influenza is usually aimed at fighting two influenza viruses.Influenza A And against stumps (or stumps)Influenza BAs far as influenza A viruses are concerned, they are divided into subtypes based on the location of two surface proteins:Hemagglutinin (H) Ella Neuraminidase (N).It is for this reason that the virus exists H3N2, H5N8, H1N1 By analogy, they are divided into more subgroups. On the other hand, influenza B viruses belong to two main lineages: B/ Victoria electronic B/ Yamagata.
As pointed out, experts conduct tests every year to evaluate which strains are in circulation Sequencing A biological sample taken from a patient. As of March 2020, monitoring laboratories no longer detect the H3N2 (3c3) and B/Yamagatanon influenza virus strains, so experts believe that they may have become extinct due to anti-Covid measures. As Professor Krammer and Professor Bedford explained to STAT, the fact that the laboratory did not find them does not mean that they have been confirmed missing, but due to the restrictions we have learned to endure, this situation may indeed happen for about a year and a half.
