New Coronavirus mutation – AY.4.2, – representing a variety of already known delta variant of the SARS-COV-2 virus, has been revealed in several countries. What is this Coronavirus mutation, and is it dangerous?
Deutsche Vella writes that the mutation of the Coronavirus SARS-COV-2 with the classification of AY.4.2 in Europe also call Delta-Plus. For the first time, she was revealed in the UK in June 2021. Until today, most cases of infection are recorded in the United Kingdom. According to the site of COV-Lineages, by October 22, this mutation of Delta option was already detected by 20,000 people.
other countries in which the relatively widespread distribution of Delta Plus is observed are Denmark (230 cases) and Germany (according to the Robert Koch Institute (RKI), 280 cases). Even in several European countries, this version of Coronavirus has revealed, but the indicators of infection them there have not yet exceeded hundreds of cases. Israel, USA, Canada, Japan, Russia – the only states outside of Europe, where there are already people infected with Delta-Plus mutation. In all these countries, we are talking about isolated cases of infection.
There is no evidence that Delta-Plus is more dangerous than delta option. In both cases, the difficult course of COVID-19 disease, which Coronavirus may cause, threaten the elderly.
According to the British Ministry of Health, the mutation of Delta-Plus is 10% detached delta option. This is not a significant difference. For comparison: Alpha and Delta options were 60% contagious in the original version of the SARS-COV-2 virus, identified in the Chinese Uhana in 2019.
Coronavirus called Delta-Plus is characterized by two mutations on spike (spike) proteins. These mutations received the names A222V and Y145H. Apparently, it is with their presence that relatively unlightly increasing the level of contrast to the new variety of coronavirus delta-option. Meanwhile, the same mutations on spikelists met earlier and other options for coronavirus.
While the emergence of the new Coronavirus mutation does not cause serious concern in the World Health Organization. The name this mutation will receive only if it is considered “causing concern” or “causing interest” (VARIANT OF INTEREST, VOI).
