The individuals who have tested positive and their contacts are all isolating. BA.2, a SARS-CoV-2 Omicron Variant, Explained - Health We have now identified cases in the East Midlands, East of England, London, South East and North West. At this point it is not possible to determine where the sublineage may have originated. As I previously reported, omicron subvariants have a shorter incubation period, which is why the symptoms may appear earlier. BA.1 accounts for most of the cases. Its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. Well send you a link to a feedback form. Dr Jenny Harries, Chief Executive ofUKHSA, said: We are continuing our efforts to understand the effect of this variant on transmissibility, severe disease, mortality, antibody response and vaccine efficacy. For the first time, this data includes analysis on vaccine effectiveness 15+ weeks after the booster dose. "We must remain vigilant and take up vaccinations. Spector shared a list of symptom prevalence from people who had tested positive for COVID, most of whom were estimated to have caught BA.2, he said. Susan Hopkins, Chief Medical Advisor at UKHSA, said: This latest set of analysis once again demonstrates that a booster dose of the vaccine provides you with significant protection against hospitalisation from Omicron. Omicron has branched into three lineages, explains Thomas Russo, M.D., professor and chief of infectious disease at the University at Buffalo in New York: BA.1, BA.2, and BA.3. Analysis shows that protection against symptomatic disease 2 to 4 weeks after a booster dose ranges from around 65% to 75%, dropping to 55% to 65% at 5 to 9 weeks and 45% to 50% 10 weeks or more following the booster dose. BA.2 Symptoms Doctors Are Seeing The Most Right Now - Yahoo! News Covid BA.2 Omicron variant: The key symptoms to look out for UKHSA is gathering scientific information as quickly as possible in order to inform the right balance of interventions to prevent transmission and protect lives. How are Covid rules changing across UK schools? The most affected local authorities are West Northamptonshire, where there are 49 confirmed cases and 68 SGTF, and Manchester, where there are 7 confirmed cases and 61 SGTF. These include a high temperature, a new. We are particularly grateful to health protection specialists and the government of South Africa for early sharing of local information on the omicron variant in an exemplary way to support global health security. The data so far suggests an increase in overall reinfection rates, alongside an increase in first infections. The latest version raising alarms is an emerging subvariant of Omicron called BA.2. UKHSA is undertaking further detailed studies. What We Know about Omicron's BA.2 Variant So Far UKHSAreleases weekly updates on the number of confirmed new cases of variants of concern and variants under investigation identified in the UK. This data shows that protection against severe illness from COVID-19 remains at over 90% in those aged 65 and over up to 14 weeks after a booster dose. Both have links to travel to Southern Africa. The most common omicron-related symptoms are: Cough. Why Alex Murdaugh was spared the death penalty, Why Trudeau is facing calls for a public inquiry, The shocking legacy of the Dutch 'Hunger Winter', Why half of India's urban women stay at home. UKHSAwill continue to carry out laboratory and epidemiological investigations to better understand the characteristics of this variant. Ba.2 Omicron Variant Symptoms - SymptomsTalk.net The latest UK Health Security Agency (UKHSA) COVID-19 variant technical briefing, published today, includes updated epidemiological analysis which indicates that Omicron BA.5 has, as expected, become the dominant SARS-CoV-2 variant in the UK. Its very likely that we will find more cases over the coming days as we are seeing in other countries globally and as we increase case detection through focused contact tracing. After 2 doses, vaccine effectiveness was 9% and 13% respectively for BA.1 and BA.2, after 25+ weeks. According to the World Health Organization (WHO), nearly 99% of viral DNA submitted to the global GISAID database as of 25 January were identified as this sub-variant. In its early days, the variant caused an alarming spike in COVID-19 cases in South Africathey went from 300 a day in mid-November 2021 to 3,000 a day at the end of that month. This is more promising data which reinforces just how important vaccines are. When the reduced risk of hospitalisation was combined with vaccine effectiveness against symptomatic disease, the vaccine effectiveness against hospitalisation was estimated as 52% after one dose, 72% 2 to 24 weeks after dose 2, 52% 25+ weeks after dose 2 and 88% 2 weeks after a booster dose. In the last week, VUI-21OCT-01 accounted for approximately 6% of all Delta cases. More investigation is required to fully determine the extent of these mutations impact. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. As with other kinds of variant, most will die off relatively quickly. So far, there is insufficient evidence to determine whether BA.2 causes more severe illness than Omicron BA.1, but data is limited and UKHSA continues to investigate. UKHSA is monitoring this closely. These are potentially biologically significant mutations which may change the behaviour of the virus with regards to immune escape, transmissibility or susceptibility to treatments, but this has not been proven. Omicron soon began branching off into a number of subvariants: BA.2 took off in the spring, and BA.5 came to dominate towards the end of the summer. As of 20 October, there were 15,120 cases of VUI-21OCT-01 confirmed by whole genome sequences in England since it was first detected in July. This analysis found that the risk of presentation to emergency care or hospital admission with Omicron (testing for symptomatic or asymptomatic infection) was approximately half of that for Delta, while the risk of hospital admission alone with Omicron was approximately one-third of that for Delta. Nine cases have also been identified in Scotland, with 5 cases in the Lanarkshire area and 4 in the Greater Glasgow and Clyde area. Of symptomatic cases, loss of smell and taste was found to be more common in people who tested positive for Delta than those who had Omicron. New Covid Omicron BA.2 variant - Two unusual symptoms to watch for The Philippines' Department of Health (DOH) said the BA.2 sub-lineage was already prevalent in samples it received at the end of January. The UK Health Security Agency (UKHSA) has published the latest Variant Technical Briefing. The v Case rates remain high throughout the UK and we must remain vigilant and take up vaccinations. These are potentially biologically significant mutations which may change the behaviour of the virus with regards to vaccines, treatments and transmissibility. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. The total number of confirmed cases in England is now 5. Omicron BA.2 lacks the genetic deletion on the spike protein which produces S-gene target failure (SGTF) in some polymerase chain reaction (PCR) tests, which has been used as a proxy for Omicron cases previously. Night sweats Scratchy throat Dry cough Mild muscle aches In data published by the UKHSA on January 14, they found that NHS test and trace data revealed a loss of smell or taste was reported less. So, like the original omicron strain (BA.1), the primary symptoms of a mild BA.2 infection are a cough, fever, fatigue and possible loss of taste or smell. The UK Health Security Agency (UKHSA) has published a new variant technical briefing containing updated analysis on Omicron hospitalisation risk and vaccine efficacy against symptomatic disease and hospitalisation. More recent data on Omicron cases is published regularly here. Two major BA.2 variant symptoms include dizziness and fatigue, as I wrote for the Deseret News. Stay at home if you have any respiratory symptoms or a fever and limit contact with others until you are feeling better, particularly if they are likely to be at greater risk if they contract COVID-19. Read about our approach to external linking. While there is a suggestion that this wanes slightly after 15 weeks, protection in this age group remains high at over 85%. It is still too early to determine next steps, so please stay cautious this Christmas and get your booster as soon as possible to protect yourself and your loved ones. It is projected that if current trends continue unchanged, the UK will exceed one million infections a day by the end of this month. There is further data showing that effectiveness against symptomatic disease is significantly lower compared to the Delta variant, and wanes more quickly. Stealth BA.2 Omicron Variant Can Reinfect People Who Had BA - Newsweek Covid: Rise in UK infections driven by BA.2 Omicron variant Those mutations are shared with the original omicron, but BA.2 also has . While signs remain encouraging on Omicrons severity compared with Delta, the high levels of community transmission continue and may cause pressures on health services. Cases have been confirmed through whole genome sequencing in all 9 regions of England. Please wear face coverings in line with government guidance, let in fresh air when mixing indoors and wash your hands regularly. But at that point the sub-variant still appeared to account for less than one in 20 cases. It has been designated a "variant under investigation" by British health authorities, meaning they are keeping a close watch on it, but are not overly concerned by it. It is therefore vital that people continue to exercise caution in order to limit the transmission of the virus. Neither BQ.1 nor XBB have been designated as variants of concern and UKHSA is monitoring the situation closely, as always. Consider wearing a face covering when in crowded places. The newest COVID variant taking the world by storm is Omicron's stealthy sub-variant BA.2, and it seems to have brought on a new barrage of gastrointestinal symptoms with it. Vaccination is critical to help us bolster our defences against this new variant please get your first, second, third or booster jab without delay. When combined with VE against symptomatic disease, the reduced risk of hospitalisation climbed to 92% 2 to 4 weeks after a third dose of the vaccine, down to 83% after 10 weeks or more. Dr Jenny Harries, UKHSA Chief Executive, said: Our latest analysis shows an encouraging early signal that people who contract the Omicron variant may be at a relatively lower risk of hospitalisation than those who contract other variants. The latest number of COVID-19 cases with mutations consistent with B.1.1.529 in England are published on UKHSAs social media channels. None of the cases to date is known to have been hospitalised or died. The individuals and their households have been told to self-isolate. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. This paper can be found as a pre-print, and the data is referred to in the latest vaccine surveillance report. However, some experts believe that BA.2 doesn't present symptoms different from the original Omicron. If you develop any symptoms, isolate immediately and get a PCR test. By the summer of 2022, the BA.5 variant was the most dominant strain in the US. Following the first 2 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529 on 27 November, the UK Health Security Agency (UKHSA) has identified one further case of COVID-19 with mutations consistent with B.1.1.529 in the UK. The latest variant technical briefing suggests that Omicron continues to grow rapidly in all regions of England as measured by confirmed cases and S gene target failure (SGTF). This is to be expected and UKHSA is monitoring the situation closely. In total, 40 countries have uploaded 8,040 BA.2 sequences to GISAID since 17 November 2021. Since then, the Centers for Disease Control and Prevention (CDC) has classified two subvariants, BA.1.1 and BA.2. We now know that BA.2 has an increased growth rate which can be seen in all regions in England. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately.. BA.2 Symptoms Usually Appear in This Order - Yahoo! Omicron continues to grow faster than Delta, with an increased risk of transmission, particularly in contacts outside of the household. While on one hand, this statement gives a ray of hope that BA.2 sub variant of Omicron which was thought to be severe is mild as the BA.1 subvariant is, but on the other hand with the report of . 2023 BBC. There will be no other categorisation of variants, including no variant under investigation (VUI) category. These changes will take effect as of 1 April 2022 and will be reflected in full in future technical briefings. Its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. This matches a recent study led by Oxford University and the Office for National Statistics (ONS), using data from the COVID-19 Infection Survey produced by the latter. UKHSA, in partnership with scientific bodies across the globe, is constantly monitoring the status of SARS-CoV-2 variants as they emerge and develop worldwide. An estimated 78.7% of confirmed cases in England are BA.5 which was first identified in April and was designated as a Variant of Concern on 18 May. What are the different symptoms doctors are seeing with omicron BA.2 We are working as fast as possible to gather more evidence about any impact the new variant may have on severity of disease or vaccine effectiveness. The following are the symptoms of this subvariant: The most common symptom is a sore throat that causes dryness, itching, and pain in the throat Low-grade fever Runny nose Sneezing Mild to moderate fatigue Headache Our data also show that 17.5 per cent of people aged 75 years and over have not had a vaccine within the past six months, putting them more at risk of severe disease. Congestion. Data continues to show COVID-19 poses a very low health risk to children and infants. The designation was made on the basis of increasing numbers of BA.2 sequences identified both domestically and internationally. Omicron has a deletion atposition69/70of the spike proteinwhich allows it to be tracked through S gene target failure(SGTF)in some PCR tests. Although there was a rapid increase in SARS-CoV-2 infections in care homes during December 2021 in line with case rises in the community, there has not been an associated increase in hospital admissions. Recent studies suggest that BA.2 has a. As of 20 December,132individuals with confirmed Omicron have been admitted to or transferred from emergency departments. UKHSAs most recent variant technical briefing can be found on GOV.UK. It is one for the scientists to watch, rather than for the public to be alarmed about at this stage. This suggests that BA.5 is likely to become the dominant COVID-19 variant in the UK. According to the CDC, the Omicron variant spreads more easily than the original SARS-CoV-2 virus and the Delta variant. However, any stay in hospital for a child is too long if youre a parent and its important we all take precautions to avoid the spread of infection. Omicron BA.2 Variant: 5 New Symptoms That Indicates You Are Infected As set out last week, the effectiveness of all vaccines against symptomatic infection continues to be lower in all periods against Omicron compared to Delta. Early data shows that young children who are hospitalised experience mild illness and are discharged after short stays in hospital. BA.2 infections in Germany are also growing faster than BA.1 and Delta, according to Dr Meera Chand, Covid-19 director at the UKHSA. "The symptoms of the Omicron variant, which includes the BA.2 lineage, and the Delta variant, are similar," says Dr. Erica Johnson, MD, the chair of the Infectious Disease Board of the . The BA.2 subvariant has been referred to as stealth Omicron because it contains genetic mutations that can make it harder to distinguish from the . Following the change in JCVI advice earlier this week, a booster dose for everyone over 18 years is now recommended and will be available at a minimum of 3 months from your last primary course jab. March 31, 2022. It is very likely that we will find more cases over the coming days as we are seeing in other countries globally and as we increase case detection through focussed contact tracing.

We have now identified cases in the East Midlands, East of England, London and North West. Positive tests with sufficient virus detected from people arriving in the UK are sent for confirmation through Whole Genome Sequencing, regardless of the presence or absence of SGTF. Self-reported long COVID after infection with the Omicron variant in Omicron BA.2.75, the variant derived from the BA.2 lineage which was identified internationally earlier this month, has now been categorised as a separate variant and given the. Omicron BA.5 variant | COVID-19 | UC Davis Health Earlier COVID-19 variants affected the lung tissue more and had a higher likelihood of causing pneumonia and other severe outcomes. Latest updates on SARS-CoV-2 variants detected in the UK. Francois Balloux, Professor of Computational Systems Biology and director of the UCL Genetics Institute, said that BA.1 and BA.2 "can be considered as two epidemiologically largely equivalent sub-lineages of Omicron". Based on the CDC's genomic surveillance, the BA.2 or stealth Omicron subvariant is responsible for most new SARS-CoV-2 infections in the U.S. BA.2 is a subvariant of the original SARS-CoV-2 Omicron variant (B.1.1.529), along with BA.1.1 and BA.3. You will not always know whether someone you come into contact with is at higher risk of becoming seriously ill from respiratory infections, including COVID-19. The latest data confirmed that among those who had received 2 doses of AstraZeneca, there was no effect against Omicron from 20 weeks after the second dose. .

Getty Images BA.2 was. Runny nose/congestion. Ongoing analysis by UKHSA has found no evidence that infection with Omicron BA.2 results in a greater risk of hospitalisation, compared to Omicron BA.1. Previous variants of concern which no longer meet the criteria will be redesignated. UKHSA has updated its stay at home guidance and non-household contacts guidance to reflect changes to self-isolation requirements for contacts of people who have been identified as a suspected or confirmed case of the Omicron variant of COVID-19. Studiesof households and contactshave found that there is a higher risk of transmission to contacts from an Omicron case, when compared to Delta. Teams nationally and locally are working at pace to identify and trace all close contacts of every Omicron case. Infection rate corrected to one million infections a day. Booster jabs are protecting people against infection and severe disease so I urge you to play your part in our national mission and get boosted now. As of 24 January 2022, 1,072 genomically confirmed cases of BA.2 have been identified in England and all assessments remain preliminary whilst case numbers are relatively low. Thats why its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. SUMMARY : The basics of the Omicron sub-variant, the BA.5, which is currently the majority in France: BA.5 is more contagious than BA.2 (January wave), which was itself more contagious than BA.1 and even more than Delta (variant 2021). The full document and underlying data is available on GOV.UK. Anyone who is contacted because of a link to a probable or possible Omicron case will be asked to take a PCR test, even if they have received a positive COVID-19PCRtestwithin the last 90 days. In England, the infection rate increased in those aged 25 years to 49 years and those aged 70 years and over in the week ending 21 February 2023. BA.2 Omicron Subvariant Can Damage Your Lungs, Cause - TheHealthSite Here is what we know about it. BA.2.75.2 variant is worrying experts. Here's why - Deseret News In some countries, BA.2 accounts for more than half of sequenced Omicron cases, it adds. Vaccine effectiveness against severe disease from Omicron is not yet known but is expected to be significantly higher than protection against symptomatic disease. UKHSA has also published a breakdown of confirmed Omicron cases and SGTF cases by local authority. Working from home where possible, consistently wearing masks in crowded or enclosed spaces, washing your hands regularly and isolating and getting tested if you feel unwell are also vitally important in reducing the impact of COVID-19 this winter. This designation means that data relating to BA.2.75 will now be reported separately from other BA.2 cases. New Omicron BA.2 variant symptoms - What we know so far - Yahoo Life UK They could be strangers (for example people you sit next to on public transport) or people you may have regular contact with (for example friends and work colleagues).

As the coronavirus continues to evolve, a new highly contagious Omicron variant is appearing in India and other nations, including the United States, experts say.. This analysis excludes individuals with confirmed previous COVID-19 infection. Continue to exercise caution. Vaccination is critical to help us bolster our defences against becoming severely ill from this new variant please get your first, second, third or booster jab without delay. SGTF is not a 100% accurate test for Omicron and results are regularly evaluated against sequencing to ensure they are interpreted correctly. Getting your booster jab remains the most effective way of protecting yourself and others from infection and severe disease. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. Covid BA.2 Omicron variant: The key symptoms to look out for As with previous variants, experts believe vaccines will continue to be highly effective against severe illness, hospitalisation, and death. Professor Susan Hopkins, Chief Medical Advisor, UKHSA said: Recombinant variants are not an unusual occurrence, particularly when there are several variants in circulation, and several have been identified over the course of the pandemic to date. A runny nose, gastrointestinal issues, headache and a skin rash are other common signs and symptoms. It is not unexpected to see new lineages and continued investigation is a normal part of the surveillance of an infectious disease. This includes analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. UKHSA has also this week published further vaccine effectiveness data against hospitalisation following a booster dose. Yet fears of another Omicron wave in the United States may be. We will continue to monitor this situation closely and recommend appropriate public health measures if needed. The individuals that have tested positive and their contacts are all isolating. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. The UK Health Security Agency (UKHSA) has published the latest variant technical briefing. Two-thirds with Omicron say they had Covid before. In severe cases, the SpO2 Level may also decrease. UKHSA scientists are urging anyone who has not had all the vaccines they are eligible for to make sure that they get them as soon as possible. What experts know about COVID-19 omicron subvariant BA.2 Delta and Omicron Cases are being eclipsed by BA2 Variant rapidly. UKHSAis carrying out targeted testing at locations where the positive cases were likely to be infectious. What's the least amount of exercise we can get away with? Everybody who is contacted or has symptoms should take aPCRtest as soon as possible, even if they have received a positive COVID-19PCRtest within the last 90 days. So, like the original omicron strain (BA.1), the primary symptoms of a mild BA.2 infection are a cough, fever, fatigue and possible loss of taste or smell. This assessment is based on analysis of UK data showing increased household transmission risk, increased secondary attack rates (such as the chance of each case infecting another individual) and increased growth rates compared to Delta. COVID & Gut Health: Why Are Omicron, BA.2 Causing More - TheQuint Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. Now more countries, particularly in Asia and Europe, are reporting an increase in cases driven by BA.2. A detrimental change in biological properties (changes in transmissibility, severity or immune evasion) compared to the current dominant variant. Increased case detection through focused contact tracing has led to more cases of the Omicron variant being identified and confirmed, as we have seen in other countries globally.
