COVID-19 Hospitalizations Increase PLUS Omicron XBB “Nightmare Variant” Reinfection And Vaccination

COVID-19 Omicron update covering case counts, hospitalizations, and deaths. We then dive into the “nightmare variant” XBB’s increasing case counts, reinfection risk, and whether vaccination including the new bivalent vaccine grants protection against it.

Case counts remain at a plateau, but hospitalizations are increasing especially in those greater than 70 years olds. We discuss why this may be and what to expect. Luckily, deaths continue to decrease in number. Last year it was mid-December when case counts really started to skyrocket. We talk about what to expect in the coming month or two as the holidays continue. https://covid.cdc.gov/covid-data-trac…

Omicron variants BQ.1 and BQ.1.1 continue to increase in prevalence now accounting for greater than 50% of new infections. XBB, a recombinant Omicron variant, and BN.1 also continue to have increasing numbers (video on XBB and BN.1 linked below!). BA.5, BA.4.6, and BF.7 continue to decrease in numbers (videos on BA.5 and BA.4.6 linked below!). https://covid.cdc.gov/covid-data-trac…

XBB is a recombinant Omicron variant, which is different than the mutating Omicron variants we typically talk about. It seems to potentially have the highest degree of immune escape of most of the variants tested. The new BA.5 bivalent mRNA vaccine does seem to grant more immunity as compared to previous vaccination, but XBB remains the least protected against out of the variants tested. If a person had previous infection and the bivalent vaccine, they seem to have the most protection against variants including XBB. https://www.biorxiv.org/content/10.11… https://www.biorxiv.org/content/10.11… https://www.beckershospitalreview.com…
