"Emerging BA.2.86 Variant Poses Heightened Threat to Lung Cells and Vaccine Efficacy"

A highly mutated Covid variant, BA.2.86 "Pirola," closely related to the dominant JN.1 strain, has been found to fuse to lung cells faster than other Omicron strains, potentially indicating a more severe form of the virus. Experts suggest that this variant may exhibit signs of older, more deadly strains, raising concerns about the severity of the latest wave of coronavirus. Research indicates that BA.2.86 binds more efficiently to cells in the lower lung, resembling traits of more deadly strains before Omicron, and may pose an elevated health threat compared to previous Omicron sublineages.

"Study Warns: New Covid Variant More Deadly Than Earlier Versions"

A new study from The Ohio State University suggests that the BA.2.86 Covid variant, a mutation of the Omicron BA.2 subvariant, may be more deadly and efficient at infecting human lung cells than previous versions. The variant has been linked to a resurgence in hospital admissions, with concerns about its potential to cause more severe lower respiratory infections. However, despite lab tests indicating increased severity, official data has not reflected this. The bivalent booster vaccine has been found to be effective at neutralizing BA.2.86, explaining why it has not caused a significant wave of infections.

Rapidly Spreading COVID Variant BA.2.86 Triples in Prevalence, Poses Low Risk

The BA.2.86 variant of COVID-19 is estimated to account for nearly 1 in 10 new cases in the U.S., according to the Centers for Disease Control and Prevention (CDC). This is nearly triple the agency's previous estimate two weeks ago. The variant's prevalence is highest in the Northeast, particularly in the New York and New Jersey region. The CDC's latest estimate suggests that BA.2.86 accounts for 8.8% of new cases, up from 3.0% on November 11. While the variant does not appear to cause worse or different symptoms, it is classified as a "variant of interest" by the World Health Organization. The CDC believes that BA.2.86 does not currently drive increases in infections or hospitalizations in the U.S.

Rapidly Spreading COVID Variant BA.2.86 Poses Low Public Health Risk

The BA.2.86 variant of COVID-19 has tripled in prevalence in the past two weeks, accounting for nearly 1 in 10 new cases in the United States, according to the CDC. The variant is spreading most rapidly in the Northeast, particularly in New York and New Jersey. While early projections on the variant's prevalence may be less reliable, the CDC has noted a recent increase in emergency department visits linked to COVID-19 nationwide. However, the BA.2.86 variant is considered to pose a "low" public health risk, and current vaccines are expected to be effective against it and its subvariant, JN.1.

Rapid Surge: COVID Variant BA.2.86 Triples in CDC Estimates

The BA.2.86 variant of COVID-19 now accounts for nearly 9% of new cases in the U.S., according to new estimates from the Centers for Disease Control and Prevention (CDC). This is nearly triple the previous estimate two weeks ago. The variant is most prevalent in the Northeast, particularly in the New York and New Jersey region. While early data suggests that BA.2.86 does not cause worse or different symptoms, the World Health Organization has classified it as a "variant of interest" due to a rise in cases. The CDC has also noted a renewed increase in COVID-19 indicators across the country, particularly in the Midwest.

The Concerning Rise of Covid Variant JN.1: What You Should Know

The JN.1 variant, a descendant of the BA.2.86 variant, is causing concern among scientists due to its potential for increased infectivity and vaccine evasion. Detected in the United States and 11 other countries, this variant is contributing to a surge in COVID-19 infections globally. However, the CDC reassures that JN.1 and BA.2.86 are rare and make up less than 0.1% of SARS-CoV-2 viruses. The spike protein, which is targeted by vaccines, has a single change in JN.1 compared to BA.2.86. The CDC believes that updated vaccines will likely provide protection against both variants, and treatments and testing should remain effective. Monitoring for the impact of new variants on vaccines, tests, and treatments continues, with prompt public alerts if any concerning developments arise.

"Unraveling the Latest COVID Variants: JN.1, HV.1, and Pirola - What You Must Know"

The JN.1 variant, a descendant of the Omicron variant, has been flagged in a CDC report and is emerging in Europe and the US. It differs from its predecessor, the BA.2.86 variant, by a single mutation in the spike protein. While JN.1 is not widespread, it has been detected in 12 countries and is increasing in frequency in France. Symptoms are similar to previous variants, and updated COVID-19 vaccines are expected to block it. Vaccination is recommended for best protection against new variants.

COVID Booster and New Vaccine Locations and Costs in Michigan

The BA.2.86 subvariant of COVID-19 has been identified in Michigan but is not currently causing a significant increase in infections or hospitalizations. An updated booster shot that targets this variant is now available, but it is no longer free for most people and the cost will depend on individual health insurance. The dominant strain in Michigan is EG.5, followed by XBB 1.16. The BA.2.86 variant has been detected in multiple states and countries, but it is too soon to determine if it is more transmissible. The CDC estimates that around 97% of the U.S. population has antibodies to COVID-19, providing some level of protection against severe disease from the BA.2.86 variant. Individuals can find locations to receive the booster shot, and most insurance providers should cover the cost.

Rapid spread of BA.2.86 COVID variant detected in multiple states

The highly mutated BA.2.86 variant of the COVID-19 virus has been detected in at least 10 states in the United States. While it remains a small fraction of new cases nationwide, health authorities believe it is spreading widely around the world. The variant has shown the ability to drive outbreaks, but there is limited evidence of it causing more severe illness. Early research suggests that current COVID-19 vaccines should be effective against BA.2.86. Scientists are continuing to study the variant and its transmission patterns, while officials express cautious optimism that the current wave of COVID-19 may have passed its peak.

"UKSHA: England Reports 34 Cases of Highly Mutated COVID Variant"

The UK Health Security Agency (UKSHA) has confirmed 34 COVID-19 cases in England linked to the highly mutated variant BA.2.86. This variant carries over 35 mutations compared to the dominant variant XBB.1.5 and is similar to the Omicron variant. Five patients have been hospitalized, but no deaths have been linked to this emerging variant. The majority of cases were identified in a care home outbreak in Norfolk. Moderna and Pfizer have reported that their updated vaccines show strong responses against the BA.2.86 subvariant. While it is too early to draw conclusions about its behavior in the wider UK population, the variant appears to be transmissible in close contact settings. The UKHSA is working to determine the full extent of community transmission.

Moderna's Updated Covid Vaccine Proven Effective Against BA.2.86 Variant

Moderna announced that its latest Covid booster is effective against the BA.2.86 omicron subvariant, which has raised concerns due to its high number of mutations. The booster generated a strong antibody response against BA.2.86, according to Moderna. Although the variant has not yet become widespread in the United States, it has alarmed experts and health officials. The data provided by Moderna has not been reviewed by outside scientists, but the company is the first to release data on the effectiveness of its booster against the new variant. The current surge in Covid cases and hospitalizations in the U.S. is primarily driven by infections with XBB lineage viruses, not the BA.2.86 variant, according to the CDC. Moderna's updated booster, along with boosters from Pfizer-BioNTech and Novavax, is expected to be authorized by the FDA soon and is designed to target the XBB.1.5 omicron subvariant.
