COVID-19 Update: Omicron XBB.1.5 Variant Rapidly Spreading in US
Omicron variant XBB.1.5 is rapidly spreading in the US, having increased from 8% to 28% in nationwide prevalence over the past four weeks. This growth pace is similar to that seen with the still predominant BQ.1 and BQ.1.1 (BQ.1x) variants, which are now in modest decline in the US. XBB.1.5 first emerged in the northeastern US, where it quickly outcompeted other variants and now accounts for an estimated 73% of cases. All other Omicron variants circulating in the US are stable or declining in prevalence. See HERE Health experts believe the XBB.1.5 variant is the most transmissible variant yet observed and will likely soon predominate in the US. See HERE In New York City, where the XBB.1.5 variant likely first emerged, it now accounts for roughly 80% of cases, and both case transmission and hospitalization have been increasing over time as XBB.1.5 has surged.
