From January 20, 2023 post.
CDC projects that the Omicron variant XBB.1.5 now predominates in the US, accounting for 49% of COVD-19 cases nationwide. The previously dominant BQ.1 and BQ.1.1 (BQ.1x) variants, which are now in modest decline, account for most other cases, approximating a 40% prevalence. XBB.1.5 first emerged in the northeastern US, where it now accounts for roughly 85% of cases. All other Omicron variants circulating in the US are declining in prevalence and CDC has reported no new emerging variants of interest or concern on the horizon. See HERE US health experts believe that XBB.1.5 will soon account for nearly all cases in the US as geographic spread from the Northeast continues. Disease severity and vaccine protection remain uncertain due to the lack of real-world data, but a recent risk assessment by the World Health Organization (WHO) concluded that XBB.1.5 is the most transmissible variant observed to date but it contains no genetic mutations known to cause more severe disease.
