Double poison in one! The variant of "Deltarchon" was first confirmed.

On March 8, researchers from the Mediterranean Institute of Infectious Diseases Medicine and Teaching in Marseille, France, published an article on medRxiv, a pre-printed website for medical research papers, saying that they confirmed the existence of this new variant through genome sequencing. In addition, this variation has been found in many parts of France.

In addition, data provided by the Global Influenza Sharing Database (GISAID) show that cases related to "Delta Xiong" have also been found in Denmark and the Netherlands. Helix, a California-based genetic research company, found two cases in the United States. According to the British "Guardian" report, about 30 cases of "Delta Joan" have been confirmed in Britain. Moreover, according to Giselle, this new variety may have spread among people from June+10 in 5438.

French researchers pointed out that a new hybrid variant "Deltarchon" was produced by recombination. The so-called recombination is that two different variants of a virus infect a patient at the same time and exchange genetic material to produce new offspring. This paper published in medRxiv points out that the "backbone" of the "Deltarchon" variant comes from the Delta variant; And its spike protein, Dr. Sumiya Swaminatan, chief scientist of the World Health Organization (WHO), wrote on Twitter on March 8: "We already know that when several COVID-19 varieties spread, recombination events may occur in humans or animals. Now, we need to wait for experiments to determine the characteristics of this new variety. "

Maria van Kerckhoff, technical director of WHO in COVID-19, said at a news conference that so far, scientists have not found any changes in the severity of the new strain compared with the previous COVID-19 strain, but many scientific studies are under way.

"Unfortunately, we do see the emergence of new recombinants, because viruses are like this, and they will change over time," Kirchhoff said. COVID-19 has a strong ability to spread, it will infect animals and may infect humans again. "
