#China, Pang Xinghuo, Deputy Director of #Beijing CDC and Member of the National Expert Group on New Coronavirus Pneumonia: ''During the monitoring of variant strains in the local #population, the city has not found the prevalence of #XBB, #BQ1 and other strains. #BF7 and #BA52, a subclade of BA.5, were still the dominant strains among the prevailing strains.'', https://news.sina.com.cn/c/2023-01-06/doc-imxzfymz2059134.shtml

''For locally-acquired infections, data presented were based on more than 2000 #genomes collected & sequenced from 1 Dec. '22. #China #CDC analysis showed a predominance of #Omicron #BA52 & #BF7 among locally acquired infections. BA.5.2 & BF.7 together accounted for 97.5% of all local infections as per genomic sequencing. A few other known Omicron sublineages were also detected albeit in low percentages... no new variant has been reported'', https://www.who.int/news/item/04-01-2023-tag-ve-statement-on-the-3rd-january-meeting-on-the-covid-19-situation-in-china

''According to the study, 30 #Omicron strains that have been identified globally were measured in more than 300 randomly selected viral #WGS from #patients in #Shanghai, including mainly #BF7, #BA52, and the recently emerged #BQ1 and #XBB.'', https://journal.hep.com.cn/fmd/EN/10.1007/s11684-022-0981-7

''Since the beginning of December, the #China CDC has completed the #WGS of 1,142 cases through a sampling survey and found that the #Omicron subvariants #BA52 and #BF7 were the dominant strains, accounting for more than 80 percent of the total, said Xu. There are also seven other subvariants of Omicron circulating.'', GT: https://www.globaltimes.cn/page/202212/1282775.shtml
