CDC Update After COVID Variant BA.2.86 Detected in U.S.

— August 24, 2023 | Newsweek | By Pandora Dewan, Science Reporter

There have been numerous variants of the SARS-CoV-2 virus so far, including the highly transmissible Omicron strain that made headlines in 2022. However, according to the CDC, the new BA.2.86 has even more additional mutations compared with previously detected Omicron variants.

The large number of mutations raises concerns that the new variant may be more effective at evading our existing immunity to the virus, either through vaccinations or previous infections. However, it is too soon to say how it will impact global immunity, as samples are not yet broadly available for lab-based antibody testing.

"Nearly all the U.S. population has antibodies to SARS-CoV-2 from vaccination, previous infection, or both, and it is likely that these antibodies will continue to provide some protection against severe disease from this variant," the CDC said. "This is an area of ongoing scientific investigation."

Only nine cases of the new strain have been confirmed so far: three in Denmark; two in South Africa; one in Israel; two in the U.S.; and one in the U.K. However, the variant has also been detected in U.S. waste-water samples.

With such a small number of confirmed cases, it is too soon to know how transmissible the new variant is, although its detection across multiple continents does indicate some degree of transmissibility.

The severity of disease caused by BA.2.86 is also unclear. "At this time, locations where this variant have been detected have not experienced increases in transmission indicators (e.g., cases, emergency department visits) or hospitalizations out of proportion to those seen in neighboring locations," the CDC said. "However, it is early in the emergence of this variant and too soon to evaluate impacts based on these indicators."

The good news is that, from what we know so far, the existing detection tests and medications used to treat COVID-19 appear to be effective against this new variant.

There are a lot of unknowns surrounding BA.2.86, but to stay safe, the CDC recommends the following actions:

Stay home if you are sick.

Get tested for COVID-19 if you feel flu-like symptoms.

Improve ventilation.

Wash your hands.

Get vaccinations as recommended by your health provider.

Omicron: What to Know About the New COVID Variant XBB1-16

Hey everyone,

I just came across an article on Nation Insight Feed that I think is really important to share. It's about the new COVID-19 variant called Omicron, also known as XBB1-16. According to the article, this variant is causing concern among health officials because it has a high number of mutations that could make it more transmissible and potentially more resistant to vaccines.

If you want to stay informed about this new variant, I highly recommend reading the article on Nation Insight Feed. It breaks down what we know so far about Omicron, including its origins, symptoms, and how it differs from previous variants. It also includes information on what steps you can take to protect yourself and others.

Here's the link to the article: https://www.nationinsightfeed.com/2023/05/omicron-what-to-know-about-the-new-covid-variant-xbb1-16-204598.html

Stay safe and stay informed!

Dr. Oliveira is the director of the Centre for Epidemic Response and Innovation in South Africa.

As a virus scientist in South Africa, I’ve been watching with dread as H5N1 bird flu spreads among animals in the United States. The pathogen poses a serious pandemic threat and has been detected in over 500 dairy herds in 15 states — which is probably an undercount. And yet, the U.S. response appears inadequate and slow, with too few genomic sequences of H5N1 cases in farm animals made publicly available for scientific review.

Failure to control H5N1 among American livestock could have global consequences, and this demands urgent attention. The United States has done little to reassure the world that it has the outbreak contained.

The recent infection of a pig at a farm in Oregon is especially concerning as pigs are known to be “mixing bowls” for influenza viruses. Pigs can be infected by both avian and human influenza viruses, creating a risk for the viruses to exchange genetic material and potentially speed up adaptation for human transmission. The H1N1 pandemic in 2009 was created and spread initially by pigs. Beyond the risks to its own citizens (there are over 45 cases of people in the United States getting the virus in 2024), the United States should remember that the country where a pandemic emerges can be accused of not doing enough to control it. We still hear how China did not do enough to stop the Covid-19 pandemic. None of us would want a new pandemic labeled the “American virus,” as this could be very damaging for the United States’ reputation and economy.

The United States should learn from how the global south responds to infectious diseases. Those of us working in the region have a good track record of responding to epidemics and emerging pandemics, and can help the United States identify new virus strains and offer insights into how to control H5N1. This knowledge has not come easily or without suffering; it has developed from decades of dealing with deadly diseases. We’ve learned one simple lesson: You need to learn your enemy as quickly as possible in order to fight it.

We did this during Covid. In November 2021, my colleagues and I, and others in Botswana, discovered the Omicron variant. We quickly and publicly warned the world that it could rapidly spread. This kind of transparency is not always easy because it can come at large economic cost. For example, after we shared our Omicron discovery, countries around the world imposed travel bans on South Africa ahead of December holidays, spurring backlash. Our team received death threats, and we needed security for our labs. One estimate suggests South Africa lost $63 million in canceled bookings from December to March.

But it was the right thing to do. That’s why it’s so frustrating that genomic sequences of H5N1 animal cases in the United States are not quickly made available. Sharing genomes of virus samples immediately is crucial for understanding the threat and giving the world time to prepare, including developing antivirals and vaccines. Rwanda, for example, was recently bold enough to go public with the detection of the deadly Marburg virus. Health responders there worked around the clock, and within about a month, they seem to have controlled the outbreak. Other countries in Africa have similarly and openly shared data about the spread of Mpox.

I’ve worked for decades with American scientists, and this summer I toured many of the country’s top scientific research institutions and was a speaker at one of its largest annual virology meetings. I know how flabbergasted many American scientists are about the country’s slow response to the H5N1. One highly respected American virologist, David O’Connor, told me that “it seems that the United States is addicted to gambling with H5N1. But if you gamble long enough, the virus may hit a jackpot.” A jackpot for the virus would fuel a global pandemic.

It is time to respond forcefully to this threat. The world’s scientists are here to help, in the same way as the United States has helped us so many times. Countries need to continue to support one another; we need an international scientific and medical force that can work together to respond to new epidemics and potential pandemics, including diagnosing and genetically analyzing every single sample of H5N1.

I understand that it’s not easy to persuade businesses, such as the meat and dairy industries, to allow the testing of all of their animals and staffs, and to make that data public quickly. But I also know that in the end, doing so protects lives, lessens economic damage and creates a safer world.

The world cannot afford to gamble with this virus, letting it spread in animals and hoping it never sparks a serious outbreak — or crossing our fingers that its effects won’t be serious in people. Time will tell. I hope we are not watching the start of a new pandemic unfold, with both the American and the international communities burying our heads in the sand rather than confronting potential danger.

Wang et al stipulated that, as global immunity from vaccination or prior infection becomes widespread, vaccine-resistant mutations are expected to become the dominant driver of SARS-CoV-2 evolution, enabling the virus to evade neutralizing antibodies and persist despite widespread immunity. Analyzing the evolutionary trajectories of vaccine-resistant mutations across more than 2.2 million SARS-CoV-2 genomes, they observed a strong correlation between the frequency of these mutations and vaccination rates in Europe and America:

A comprehensive research library that contains 63 peer-reviewed studies linking COVID-19 “vaccination” to the evolution of vaccine-resistant viral variants has just been published (Compiled by Dr. Steven Hatfill, MD, MMed, Erik Sass, et al). You can read it here:

The following collection of over 50 (n=63) peer-reviewed papers suggests the “vaccines” applied strong selective pressure to the fast-mutating SARS-CoV-2 virus, quickly giving rise to “vaccine”-resistant variants. It is noteworthy that variants emerged in temporal and geographic proximity to “vaccine” clinical trials or mass “vaccination”: 1. The Alpha variant was first identified in the county of Kent in southeast England in November 2020. Phase I/II clinical trials for AstraZeneca’s AZD1222 (ChAdOx1 nCoV-19) adenovector “vaccine” enrolled over 1,000 subjects in southern England in April 2020, and thousands more in the phase III trial, May-December 2020. 2. The Delta variant was first identified in Maharashtra state, India, in October 2020. Phase II/III clinical trials for the Covidshield adenovector “vaccine” based on AstraZeneca’s AZD1222 enrolled 1,600 subjects at 14 hospital centers, including eight in Maharashtra state, from July-October 2020. 3. The Omicron variant was first identified in Gauteng, South Africa, in November 2021, following an intense provincial “vaccination” campaign from August-October. On this note, public health officials have warned that “chasing variants” is likely futile:

📆 14 Feb 2024 📰 As U.S. COVID-19 Winter Wave Recedes, CDC Tracks New BA.2.87.1 Variant 🗞️ U.S. News

Meanwhile, as is always the case with COVID-19, there’s the possibility a new variant could change everything.

Globally and in the U.S., JN.1 dominates. It’s an omicron subvariant that is closely related to BA.2.86, or “pirola.”

JN.1 was responsible for more than 9 in 10 new COVID-19 infections in the U.S. in recent weeks, according to CDC estimates. The agency said JN.1 contributed to the burden of COVID-19 this winter, but added that its spread “does not appear to pose additional risks to public health beyond that of other recent variants.”

As of last week, the CDC was tracking and analyzing a new variant that hadn’t yet appeared in the U.S.: BA.2.87.1. The strain had only been found in South Africa so far.

“The fact that only nine cases have been detected in one country since the first specimen was collected in September suggests it does not appear to be highly transmissible – at least so far,” the CDC said in a post about the strain.

So why is the agency keeping an eye on this variant? Because it has highly mutated, with more than 30 changes in the spike protein of the coronavirus compared with XBB.1.5, which is the virus variant targeted by the latest vaccines.

Deciphering the Complexities of COVID-19 Variants

Introduction:

The global COVID-19 pandemic has posed an unprecedented challenge to humanity. As the virus continues its relentless spread, it constantly evolves through mutations, giving rise to an array of variants. In this in-depth journey, we will embark on a thorough exploration of the intricate realm of COVID-19 variants to equip you with the indispensable knowledge you need.

1. Unraveling the Intricate World of COVID-19 Variants:

COVID-19 variants are akin to unique adaptations of the SARS-CoV-2 virus, each sculpted by genetic mutations. These genetic transformations can lead to substantial changes in the virus's characteristics, influencing its transmissibility, disease severity, and resistance to immunity. Think of these variants as distinct "iterations" of the same virus, each bearing its genetic signature.

2. An In-Depth Exploration of Prominent COVID-19 Variants:

Alpha (B.1.1.7): First detected in the United Kingdom, the Alpha variant gained worldwide attention due to its heightened transmissibility. However, it didn't necessarily translate into more severe illness or increased fatality rates.

Beta (B.1.351): Originating in South Africa, the Beta variant raised concerns about its potential resistance to immunity, including vaccine-induced immunity. Researchers maintained a vigilant watch over its behavior.

Delta (B.1.617.2): The Delta variant, initially identified in India, has played a pivotal role in the pandemic. Its extraordinary transmissibility led to surges in cases worldwide, resulting in increased hospitalizations and posing challenges to containment efforts.

Omicron (B.1.1.529):  Omicron made global headlines due to its numerous mutations in the spike protein, the primary target of most COVID-19 vaccines. Scientists are actively researching its transmissibility, severity, and vaccine efficacy, given its potential risk.

3. Understanding the Genesis of Variants:

Why Do They Emerge? Variants are an inherent facet of a virus's life cycle. As the virus replicates and spreads, genetic changes occur. While many of these changes are random, some provide advantages to the virus. For instance, mutations that enhance transmissibility help the virus spread more efficiently from person to person, ultimately increasing its prevalence.

4. Assessing the Impact of Variants on Vaccines:

A major concern regarding COVID-19 variants revolves around their impact on vaccine effectiveness. Vaccine manufacturers and researchers vigilantly monitor these variants. While some variants may marginally reduce vaccine effectiveness, it is crucial to understand that vaccines continue to offer robust protection against severe illness, hospitalization, and death. Even when a variant affects vaccine efficacy, vaccines remain potent in mitigating the virus's impact.

In response to the emergence of variants, booster shots have been recommended to enhance immunity, especially against newer and more challenging variants like Delta and Omicron. These booster doses bolster the body's immune response, providing additional layers of protection.

5. The Pivotal Role of Public Health Measures:

Irrespective of the variants that emerge, public health measures remain crucial for controlling the spread of COVID-19. These measures encompass:

Mask-Wearing: Consistently don masks in crowded or indoor settings, especially in regions with high transmission rates.

Social Distancing: Maintain physical distance from others, particularly during close social interactions.

 Hand Hygiene: Practice regular handwashing with soap and water or use hand sanitizers.

Vaccination: If eligible, get vaccinated and adhere to guidance on booster shots when provided.

Testing and Isolation: Undergo testing if you display symptoms or have been exposed to a COVID-19-positive individual. Prompt isolation upon receiving a positive result is essential to curb further transmission.

These measures not only safeguard individual health but also act as barriers against the emergence of new variants.

Summary:

COVID-19 variants are an intrinsic part of the virus's evolution. Scientists diligently explore their characteristics and potential impact on public health. In this ever-evolving landscape, vaccination and adherence to public health measures remain our most unwavering allies in the battle against the pandemic. Staying informed and heeding guidelines from reputable health authorities, such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), are essential actions to safeguard ourselves and our communities.

By • Olalekan Fagbade COVID-19 Again; NCDC clears air on presence of new subvariants in Nigeria The Nigeria Centre for Disease Control and Prevention (NCDC) is closely monitoring the emergence of new subvariants of the Omicron variant of the SARS-CoV-2 virus. The Director-General, NCDC, Dr Ifedayo Adetifa, gave the assurance in an interview with the News Agency of Nigeria (NAN) on Saturday in Abuja. These subvariants, named EG.5 and BA.2.86, have been reported in several countries. While the EG.5 variant has been classified as a “variant of interest” with a low global risk, the BA.2.86 variant is currently under monitoring due to its substantial genetic differences from other circulating variants. NAN reports that an update from the U.S. Centre for Disease Control and Prevention (CDC) shows that at least two cases subvariant BA.2.86 have been identified in the U.S. This prompted the centre to issue a risk-assessment summary on Aug. 23, explaining what is known about it so far.   Adetifa said that the NCDC, along with its partners, was actively conducting surveillance and implementing enhanced testing measures to gather more information about these emerging variants. “It is important for the public to stay informed with verified information and continue practising preventive measures to protect themselves and their loved ones,” he said. He noted that the subvariants, EG.5 and BA.2.86, had been reported in countries such as China, U.S., Republic of Korea, Japan, Canada, Australia, Singapore, United Kingdom, France, Portugal and Spain. “The EG.5 variant, which is a descendant of XBB.1.9.2, has been identified in 51 countries. The World Health Organization (WHO) has classified EG.5 as a Variant of Interest (VoI). “However, a risk assessment conducted by the WHO has determined that this new variant poses a low risk at the global level. “It is important to note that EG.5 has not been associated with any change in symptoms or clinical manifestations, nor has it resulted in an increase in the severity of illness, hospitalizations, or death rates. “The symptoms caused by EG.5 are similar to those seen with other COVID-19 variants, including fever, cough, shortness of breath, fatigue, muscle aches, headache and sore throat,” he said. According to him, on the other hand, the BA.2.86 variant, a descendant of BA.2, has been reported in a handful of countries, including the United Kingdom, Israel, Denmark, South Africa and U.S. The director-general said that WHO had classified BA.2.86 as a Variant under Monitoring (VuM) due to its multiple genetic differences from its ancestor – BA.2, and other currently circulating XBB-derived SARS-CoV-2 variants. “As there are only a few reported cases of BA.2.86, there is not enough information to make conclusive assessments of its virulence, transmission and severity. “However, it is expected to be similar to other Omicron descendants currently circulating. “It is worth noting that while the ancestor BA.2 has been previously found in Nigeria, no BA.2.86 variant has been identified in the country,” he said. He said that the NCDC’s COVID-19 Technical Working Group (COVID-19 TWG) was actively monitoring COVID-19 epidemiology at the local, regional, continental and global levels, including the emergence of new variants. “Influenza sentinel surveillance sites continue to provide information on COVID-19 prevalence in patients with influenza-like illness and severe acute respiratory illness. “So far, there has been no observed increase in the trend of COVID-19 in this patient group,” he said. He said that the NCDC was also carrying out genomics surveillance, in spite of the low testing levels, and encourages testing locations in states to send positive samples for sequencing. “Additionally, the NCDC and its partners are working on implementing an enhanced COVID-19 testing exercise in four states to obtain more detailed information about circulating variants in the coun

try. “The distribution of COVID-19 rapid diagnostic kits is also underway to improve bi-directional COVID-19 testing,” he said. He urged members of the public to act responsibly and share only verified information to avoid unnecessary panic. “It is emphasized that COVID-19 is here to stay and mainly affects those at high risk, such as the elderly and individuals with underlying chronic illnesses. “The actions required to protect oneself and others remain the same, including getting tested for any febrile illness and respiratory symptoms, getting vaccinated against COVID-19, practising good hand hygiene, and wearing masks in high-risk situations,” he said. He said that the NCDC would continue to monitor the situation globally, especially in countries where the new variants had been confirmed. He added that the centre would provide Nigerians with scientifically-sound and evidence-based information on any changes in SARS-CoV-2 epidemiology and genomics that may pose a threat to public health.(NAN) www.nannews.ng AIR/ISHO/IGO #COVID19 #Nigeria #Subvariant

A sudden alteration that turned the world upside down

by Eeya Baguio

It started of an unknown virus that exploded like a bomb out of nowhere. No expectancy, no signals, nothing at all. Affecting people one by one, all across the world. The COVID-19 virus.

As the days gone by, turned into weeks, months, and unexpectedly, years. It has evolved into a more alarming one. Thousands of deaths being reported, lockdowns every now and then, necessities being sold out to every stores, it was a sudden alteration that turned the world upside down. Thus, given its evolution, different variants were created, in which some are very much alarming.

Alpha variant (B.1.1.7): first identified in the UK in late 2020, it spreads more easily than earlier variants and may be associated with a higher risk of hospitalization and death.

Beta variant (B.1.351): first identified in South Africa in late 2020, it may be associated with reduced effectiveness of some vaccines.

Gamma variant (P.1): first identified in Brazil in late 2020, it is similar to the Beta variant and may also be associated with reduced vaccine effectiveness.

Delta variant (B.1.617.2): first identified in India in late 2020, it is more transmissible than earlier variants and has been associated with increased hospitalizations and deaths.

Omicron variant (B.1.1.529): first identified in South Africa in late 2021, it has a large number of mutations and is still being studied, but early evidence suggests that it may be more transmissible than other variants.

It's worth noting that viruses constantly mutate, and new variants of COVID-19 are likely to emerge in the future.

New XEC Covid variant spreading 'more easily' as cases rise - Published Sept 23, 2024

By Howard Lloyd

The strain has quickly spread around the world - including Europe - and is now causing concern in the US

A new variant of Covid-19 is on the rise, according to scientists. The XEC strain started in Europe but has now spread across the globe, with research suggesting it is transmitted more easily than previous types.

Researchers say it is a recombinant variant - meaning it is created from two previously existing strains which someone may have caught at the same time. In XEC's case, it is a combination of KP.3.3 and KS.1.1. It is a genetic offshoot of omicron, a highly transmissible variant that first emerged in South Africa in 2021.

This means it shares many of the same characteristics as other omicron subvariants, such as spreading easily and causing less severe disease than the earliest SARS-CoV-2 strains.

It was first detected in Germany at the end of August and now 82 cases have been found in the UK. Doctors in the US are also concerned, with one saying it was 'just getting started'.

It has now been detected in 27 countries across Europe, Asia and North America. Despite only being found three weeks ago, 13% of cases in Germany are now the XEC variant.

Richard Orton, Bioinformatics Research Associate at the University of Glasgow, told The Conversation: "XEC appears to have a growth advantage and is spreading faster than other circulating variants, suggesting it will become the dominant variant globally in the next few months."

He added: "This new variant will probably be similar to other COVID variants in terms of the disease caused, given its similar genetic information. So symptoms such as a high temperature, sore throat with a cough, headaches and body aches along with tiredness are to be expected."

Hospitalisations with Covid in the UK are expected to increase in the weeks ahead as we move into colder weather. A new vaccination project will being next month in a bid to fight the spread of the virus.

Unraveling the Intricacies of COVID-19 Variants

Introduction:

The COVID-19 pandemic has presented us with a global challenge of unparalleled proportions. As the virus continues its relentless spread, it undergoes a subtle transformation, giving rise to various mutations and thereby creating different versions of itself, known as variants. In this in-depth exploration, we will dive deep into the complex world of COVID-19 variants to unravel what you need to know about them.

The Essence of COVID-19 Variants

COVID-19 variants are akin to distinct versions of the SARS-CoV-2 virus, each having undergone genetic mutations. These genetic alterations can result in noteworthy changes in the virus’s characteristics, including how easily it spreads, the severity of the disease it causes, and its resistance to immunity. Think of these variants as unique “strains” of the same virus, each possessing its own genetic signature.

2. A Glimpse at Common COVID-19 Variants

Alpha (B.1.1.7): First spotted in the United Kingdom, the Alpha variant quickly seized global attention due to its heightened transmissibility. However, it was not necessarily more severe in terms of causing severe illness or fatalities.

Beta (B.1.351): Originating in South Africa, the Beta variant raised concerns regarding its potential resistance to immunity, including immunity induced by vaccines. Researchers kept a vigilant eye on its behavior.

Delta (B.1.617.2): The Delta variant, initially identified in India, has been a game-changer in the pandemic. With its exceptional transmissibility, it has caused surges in cases worldwide, leading to increased hospitalizations and posing challenges to containment efforts.

Omicron (B.1.1.529): Omicron made headlines globally due to its myriad mutations in the spike protein, the primary target of most COVID-19 vaccines. Scientists are actively engaged in the study of its transmissibility, severity, and vaccine efficacy, as it poses a potential risk.

3. The Genesis of Variants: Why Do They Occur?

Variants emerge as a natural facet of a virus’s life cycle. As the virus replicates and spreads, genetic changes can manifest. These changes are often random, but some provide advantages to the virus. For instance, mutations that enhance transmissibility can assist the virus in spreading more efficiently from person to person, consequently increasing its prevalence.

4. The Influence of Variants on Vaccines

A major concern regarding COVID-19 variants revolves around their impact on vaccine effectiveness. Vaccine manufacturers and researchers maintain vigilant monitoring of these variants. While some variants may slightly reduce vaccine effectiveness, it is imperative to understand that vaccines continue to offer robust protection against severe illness, hospitalization, and death. It is crucial to reiterate that, even when a variant partially diminishes vaccine efficacy, vaccines retain their potency in mitigating the virus’s impact.

In response to the emergence of variants, booster shots have been recommended to enhance immunity, particularly against newer and more challenging variants such as Delta and Omicron. These booster doses fortify the body’s immune response, providing additional layers of protection.

5. The Perseverance of Public Health Measures

Irrespective of the variants that come and go, public health measures remain a linchpin in controlling the spread of COVID-19. These measures encompass:

Mask-Wearing: Continuously don masks in crowded or indoor settings, particularly in regions with elevated transmission rates. Social Distancing: Uphold physical distancing from others, especially when engaged in close social interactions. Hand Hygiene: Maintain consistent handwashing with soap and water or employ hand sanitizers. Vaccination: If eligible, seek vaccination and heed the advice on booster shots when provided. Testing and Isolation: Undergo testing when displaying symptoms or after exposure to a COVID-19-positive individual. Prompt isolation upon a positive result is essential in curbing further transmission. These measures not only safeguard individual health but also act as bulwarks against the emergence of novel variants.

Summary:

COVID-19 variants are an inherent element of the virus’s evolution. Scientists diligently probe their characteristics and potential impact on public health. In this dynamic landscape, vaccination and adherence to public health measures continue to be our foremost allies in combating the pandemic. Staying informed and adhering to guidelines issued by esteemed health authorities, such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), constitute essential actions to safeguard ourselves and our communities.

The panorama of COVID-19 and its variants remains in constant flux. It is imperative to rely on trustworthy sources and remain attuned to the latest information. By remaining informed and adopting responsible actions, we collectively contribute to the containment of COVID-19 and its variants.

Remember, our collective efforts wield a profound impact and are pivotal in surmounting this global challenge. Stay safe, and remain vigilant in your commitment to adhering to public health guidelines.
