WHO confirms the existence of a new variant of the new crown Deltacron, which is recombined from Delta and Omicron

Written | Edited by Wang Cong | Typesetting by Wang Duoyu | Shui Chengwen On January 7, 2022, Leondios Kostikis, a virologist at the University of Cyprus, announced the discovery of some new mutants of the new coronavirus with both Delta and Omicron mutation characteristics, and named them For: Deltacron
.

After the report, the news quickly attracted widespread international attention
.

Because the Delta mutant is highly pathogenic and the Omicron mutant is highly transmissible, many fear that this new mutant will be both highly pathogenic and highly transmissible
.

But many researchers believe that the so-called Deltacron most likely does not exist, and that the above findings are most likely the result of contamination of laboratory samples
.

However, new research suggests that this may not be sample contamination, but actually exists
.

Recently, a research team from the Pasteur Institute in France published a research paper entitled: Culture and identification of a "Deltamicron" SARS-CoV-2 in a three cases cluster in southern France in the preprint medRxiv
.

The study found the presence of new coronavirus strains with both Delta and Omicron mutation characteristics in patients with new crowns in southern France, and pointed out that "there is conclusive evidence of the existence of Delta-Omicron recombinant new coronaviruses
.
"
At present, the new mutant strain has been found in countries such as France, the Netherlands and Denmark, and the World Health Organization (WHO) has also confirmed the existence of this new coronavirus mutant strain recombined from Delta and Omicron
.

Delta and Omicron are currently the most prevalent strains of COVID-19 worldwide, which has led to some people being infected with both mutations, and when they meet in the same host cell, recombination, the mutual exchange of genetic material, can occur.
exchange, resulting in a new recombinant virus
.

These two mutants are growing in an uncontrolled explosion in Europe and the United States, so it is not surprising that Europe will be the first to see the Deltacron recombinant mutant
.

The Deltacron recombinant mutants identified this time include structures from the Delta GK/AY.
4 and Omicron GRA/BA.
1 lineages
.

Whenever a new mutant strain of Covid-19 emerges, several major questions are most concerning: first, whether it is more likely to spread; second, whether it will cause more severe symptoms; third, whether it is more likely to escape previous vaccinations or Natural immunity; the fourth is whether antibody drugs or other anti-coronavirus drugs are still effective
.

However, with so few cases so far, scientists know very little about the new mutant strain, and these questions remain unanswered
.

The World Health Organization's COVID-19 technical lead, Dr.
Maria Van Kerkhove, said at a press conference that the new crown is still spreading rapidly around the world, and the new crown pandemic is far from over
.

The presence of Deltacron has indeed been observed now, and it is likely that the mutant strain will spread further
.

The name Deltacron is a temporary name.
Due to too few cases, the World Health Organization has not classified it as a variant of concern.
If it is classified as a variant of concern in the future, the WHO will give it a name using Greek letters.
official name
.

Since the new crown pandemic, new crown mutant strains have appeared continuously.
Since the new crown vaccines that have been approved for marketing are all directed against the original new crown virus strain, the mutant strains can cause breakthrough infections in the vaccinated population, but fortunately So far, the Covid-19 vaccine has protected people well from severe illness, hospitalization and the threat of death
.

Therefore, vaccination is still a powerful means of fighting against the new crown
