The World Health Organization said omicron and its descendent lineages are still dominant globally, but have declined in relative prevalence. In the week through Jan. 22, they accounted for 53.9% prevalence among sequences submitted to a central database, down from 74.2% in the week through Dec. 25.

Pooled recombinant variant sequences rose to 24.6% from 8.8%, mostly due to XBB.1.5, which is dominant in the U.S. where most sequences were reported, the agency said in its weekly epidemiological update.
