Cyprus scientists announced in January this year that they had discovered a variant with Delta genetic material and some Omicron mutations, named “Deltacron”, which was later said to be caused by laboratory cross-contamination, but the latest UK Health Safety Agency (UKHSA) revealed , the first confirmed case of a new variant of Deltacron has appeared in China.
The British Health and Safety Agency currently uses Delta and Omicron Recombinant (Delta × Omicron Recombinant) to label, and it is listed as a weekly monitoring and investigation of variant strains. Evolved in patients, but the contagiousness or severity is unknown at this stage.
Paul Hunter, an infectious disease expert at the University of East Anglia, said that the current vaccination rate in the UK is extremely high, and the Delta and Omicron variants have strong immunity, so the new variant should not pose too much threat. Since the cases of Delta and Omicron are both decreasing, it is theoretically difficult for Deltacron to explode.
Leondios Kostrikis, a professor at the University of Cyprus, announced the discovery of Deltacron in January this year, and insisted that it was not the result of a “technical error”, but instead showed that the evolutionary pressure for the mutation of the maternal strain was not a single recombination event. , but at the time World Health Organization (WHO) experts said it may be laboratory contamination of Omicron fragments in Delta samples.
