According to real-time dynamic monitoring, no delta variant was found to be prevalent in China, nor was the recombination between the delta variant and the aumicron variant found.
From the beginning of December to the present, nine popular sub-clades of the new coronavirus have been monitored in China, all of which belong to the Amicron mutant strain.
From the beginning of December to the present, the Chinese Center for Disease Control and Prevention has completed the whole genome sequencing of 1142 cases through sampling surveys, and found that the subclades BA. 80%.
In addition, there are 7 subclades of Aomecron variant strains that are also prevalent.
Xu Wenbo introduced that no characteristic genome mutations were found in these sub-branches, and they were all imported from abroad.
In December, a total of 31 subclades of Omicron mutant strains were found imported into China, including subclades such as BQ.1 and XBB that are spreading rapidly abroad.
