CDC Walensky: U.K. Variant Now Most Dominant Strain in the U.S.
WALENSKY: “The B117 variant is now the most common lineage circulating in the United States. ... Across the country, we are hearing reports of clusters of cases associated with daycare centers and youth sports. Hospitals are seeing more and more younger adults — those in their 30s and 40s — admitted with severe disease. Data suggests this is all happening as we are seeing increasing prevalence of SARS-CoV-2 variants, with 52 jurisdictions now reporting cases of variants of concern.”
