The Centers for Disease Control and Prevention (CDC) has announced that it’s monitoring multiple recent COVID-19 variants, further complicating the landscape of strains currently circulating nationwide. Among the many variants under CDC surveillance is EU.1.1, a strain that gained attention earlier this yr resulting from its rapid emergence in several European countries.
EU.1.1 is a more distant descendant of the XBB.1.5 variant, which saw a surge earlier this yr. It possesses additional mutations in its spike protein, potentially contributing to its increased transmissibility. In keeping with the CDC’s estimates, EU.1.1 currently accounts for 1.7% of COVID-19 cases across america, even though it can have already reached as high as 8.7% of cases within the Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming region, CBS News reported.
As of late, it stays uncertain whether EU.1.1 will lead to recent or different symptoms in america. While there have been anecdotal reports, health officials have emphasized the shortage of considerable evidence indicating previous variants led to changes in the consequences of COVID-19. The evolution of immunity amongst infected individuals over time can affect how the virus manifests, further complicating reports of symptom shifts.
Nearly all Americans are estimated to own antibodies from vaccination, prior infection, or a mixture of each. The CDC reported that an increasing proportion of hospitalizations and deaths now result from reinfections.
Utah laboratories have sequenced the very best variety of EU.1.1 infections in comparison with other states, with the state’s public health laboratory reporting nearly 100 cases to global virus databases. In contrast, neighboring Nevada and Colorado labs have only reported single-digit numbers of sequenced EU.1.1 infections.
Despite the prevalence of EU.1.1 cases in Utah, the state’s overall COVID-19 trends align with the remainder of the country, currently reflecting record-low levels observed through the previous spring and summer months.
A recent evaluation by academic and federal modelers predicts that america will likely experience intermittent periods of reduced COVID-19 hospitalizations and deaths through the warmer months for not less than the following two years. Subsequent peaks through the fall and winter are projected to be lower than previous records, per CBS News.
CDC data indicated that the pace of recent COVID-19 hospital admissions and emergency room visits in Utah largely slowed or plateaued in recent months. Reported nursing home cases also remain significantly lower than winter peaks.
The CDC currently categorizes the vast majority of variants nationwide into 4 strains throughout the XBB family of SARS-CoV-2 variants. XBB.1.5, the biggest strain, is projected to account for 27.0% of infections. XBB.1.9.2 and XBB.1.9.1 together make up 24.4% of cases. XBB.1.16 follows as the following largest strain, representing 19.9% of circulating viruses. XBB.2.3 accounts for 10.6% nationwide.
Earlier this month, the Food and Drug Administration (FDA) beneficial that COVID-19 vaccines for the autumn ought to be updated to focus on the XBB.1.5 variant. Nevertheless, officials assert that the brand new shots will enhance immunity against all these strains and their various descendants, as they’re closely related.
Moderna announced Thursday that it has formally submitted its newly revised shots for emergency use authorization, specifically designed to focus on XBB.1.5. The corporate also highlighted research suggesting that the brand new vaccine would generate robust immune responses able to protecting against XBB.1.16, XBB.2.3 and their relatives.
