The omicron sublineages named BQ.1 and XBB do not appear to have immune escape mutations that warrant being designated as variants of concern, said a WHO advisory panel. As of Oct. 25, the XBB and XBB.1 lineages had been detected in 35 countries.
The omicron sublineages named BQ.1 and XBB do not appear to have immune escape mutations that warrant being designated as variants of concern, a World Health Organization advisory panel said Friday.
As of Oct. 25, the XBB and XBB.1 lineages had been detected in 35 countries, according to a WHO weekly update from Thursday. The two are BA.2.10.1 and BA.2.75 recombinants, which were found in 26 countries in the previous week. “While there are no data on severity or immune escape from studies in humans, BQ.1* is showing a significant growth advantage over other circulating Omicron sublineages in many settings, including Europe and the US, and therefore warrants close monitoring,” said the panel.
