According to the latest data from the British Safety and Health Bureau, 637 cases of XE and two Omicron subtype recombinant strains have been found in this country.
Earlier, Cypriot scientists announced the discovery of a new COVID-19 mutant, which is a recombinant of Delta and Omicron, the so-called "Delta Tarqiong".
The World Health Organization (WHO) and some experts, including Imperial College London in London, UK, said that the Deltarjon mutant discovered by Cypriot scientists was probably due to a contaminated sequence.
The British "Daily Mail" reported that the British Health and Safety Agency has officially monitored "Delta Xiong". In the latest weekly monitoring report of mutant strains of public health concern, "Deltarjon" was added.
However, the agency did not publish data on cases of virus infection. UKHSA said in the weekly monitoring report that the infectivity or severity of Deltarchon is still unknown. And whether it will affect the effectiveness of the vaccine. An infectious disease expert at the University of East Anglia in the United Kingdom said that this mutant strain should not pose much threat in theory.
At present, French scientists have confirmed for the first time that COVID-19's "Delta Clone" mutation does exist through genome sequencing, which combines COVID-19's Delta mutation and Omicron mutation. Related cases have been reported in the United States and Europe.
? On March 8, researchers from the Mediterranean Institute of Infectious Diseases 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 gene sequencing. In addition, this variation has been found in many parts of France.
According to the data provided by the global influenza database, "Deltarjon" related cases have also been found in Denmark and the Netherlands. According to Giside, this new variety may have spread among people from June+10, 65438.
? Maria Van Kerckhoff, technical director of WHO in COVID-19, said at a news conference that so far, scientists have not found any change in the severity of the new strain compared with the previous COVID-19 strain, but they are studying it.
Hopkins pointed out that so far, there is not enough evidence to conclude that XE strain is infectious, serious or affects the effectiveness of the vaccine.
Looking forward to further research by scientists.
