According to a report by the American Fun Science website on March 11, French scientists have confirmed for the first time through genome sequencing that the variant of the new coronavirus #deltacron, which has previously attracted a lot of attention, does exist. Variations in the body and Omicron variants. Cases have now been reported in the United States and Europe.

Researchers at the Institute for Medical and Teaching of Mediterranean Infectious Diseases in Marseille, France, published an article on medRxiv, a preprint site for medical research papers, on March 8 that they confirmed the existence of the new variant through genome sequencing. Moreover, the variant has been detected in several regions of France.

In addition, data provided by the Global Influenza Sharing Database (GISAID) showed that cases related to "Delta Chron" were also 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, the United Kingdom has confirmed about 30 "Delta Coron" cases. And, according to GISAID, the new variant may have been circulating in the population since January.

World Health Organization (WHO) chief scientist Dr Sumia Swaminathan tweeted on March 8: "We already know that recombination events can occur in humans or animals when multiple SARS-CoV-2 variants are circulating. appeared in the body. Now, we need to wait for experiments to characterize this new variant."
