COVID-19 Update: Omicron XBB.1.5 Variant Rapidly Spreading in US | Pexels
From February 3, 2023 post.
CDC projects that the Omicron variant XBB.1.5 now accounts for 66% of COVID-19 cases nationwide, with most remaining cases due to the quickly receding BQ.1 and BQ.1.1 (BQ.1x) variants. XBB.1.5 first emerged in the northeastern US, where it now accounts for roughly 92% of cases. It is expected that XBB.1.5 will likely account for nearly all US cases within the next month or so. All other Omicron variants currently 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 Although clinical data are still limited, US health experts remain hopeful that the highly transmissible XBB.1.5 variant will not cause more severe disease and that the updated booster will continue to offer protection against hospitalization and death. See HERE A recent study by CDC has shown that the bivalent mRNA booster dose provided additional protection (40%-50%) against symptomatic XBB/XBB.1.5 infection for at least the first 3 months after vaccination in persons who had previously received 2–4 monovalent vaccine doses.
