No new Covid variants emerged during China’s recent outbreak: Lancet study
Beijing, Feb 10 (PTI) Two known Omicron sub-variants – rather than any new variants – have chiefly been responsible for the recent COVID-19 surge in China, according to a study of cases in Beijing published in The Lancet Journal.
The analysis suggests Omicron sub-variants, BA.5.2 and BF.7 – among the most dominant variants in Beijing during 2022 – accounted for more than 90 per cent of local infections between November 14 and December 20, 2022.
The results represent a snapshot of the pandemic in China, due to the characteristics of Beijing’s population and the circulation of highly transmissible COVID-19 strains there, the researchers said.
