Thats why its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. According to Baric, Omicron is the first SARS-CoV-2 variant to evolve in the context of mounting immunity in the populationthe result of vaccines and prior infection with other forms of the . This new UKHSA data on Omicron is promising while 2 doses of the vaccine arent enough, we know boosters offer significant protection against the variant and early evidence suggests this strain may be less severe than Delta. 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. Check benefits and financial support you can get, Find out about the Energy Bills Support Scheme, National flu and COVID-19 surveillance report, higher risk of becoming seriously ill from respiratory infections, including COVID-19, this data should be interpreted with caution, This assessment is based on analysis of UK data, data on Omicron cases is published regularly here, Six cases of the SARS-CoV-2 variant known as B.1.1.529, Investigation of SARS-CoV-2 variants of concern: variant risk assessments, Investigation of SARS-CoV-2 variants: technical briefings, Coronavirus (COVID-19): guidance for local government, let fresh air in if meeting others indoors, wear a face covering or a face mask, particularly if you are in crowded and enclosed spaces. At this point it is not possible to determine where the sublineage may have originated. The Delta variant sub-lineage known as Delta AY.4.2 was designated a variant under investigation (VUI) by the UK Health Security Agency (UKHSA) on 20 October 2021 and has been given the official name VUI-21OCT-01. This designation means that data relating to BA.2.75 will now be reported separately from other BA.2 cases. The UK Health Security Agency (UKHSA) has announced the emerging SARS-CoV-2 variant known as B.1.1.529 as a variant under investigation (VUI). Scratchy throat. The odds of reporting long COVID symptoms four to eight weeks after a first COVID-19 infection were 21.8% higher after an infection compatible with Omicron BA.2 than Omicron BA.1 among adults who were triple-vaccinated when infected; this was after adjusting for socio-demographic characteristics and time since last COVID-19 vaccination. This is more promising data which reinforces just how important vaccines are. None of the cases to date is known to have been hospitalised or died. Delta remains the predominant variantin England, accounting for over 99% of all COVID-19 cases. It is also vital to continue with all the other precautions we have become used to throughout the pandemic keep indoor areas well ventilated, wear a face covering in enclosed spaces, and take a rapid lateral flow (or LFD) test before a situation where you may be at high risk of catching or passing on the virus. There are small numbers of cases in the UK and this designation is intended to allow investigation into the specific properties of this variant. A number of Omicron variants are currently circulating in England, many of which have acquired mutations which may produce a degree of immune escape. UKHSA is monitoring the situation closely, in partnership with scientific and public health organisations across the world. 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 Available data are limited at this early stage, but it remains likely that the cases identified so far are a result of a number of separate introductions into the country. Dr Susan Hopkins, Chief Medical Advisor for UKHSA, said: Ongoing variant analysis is an important part of our pandemic response. The analysis shows that coronavirus (COVID-19) cases in the UK are primarily made up of BQ.1 and its sublineages, consistent with the UKHSA risk assessment published in October. This new mutation dubbed BA.2.75 is concerning scientists because it appears to spread fast, bypassing the protection offered by COVID-19 vaccines and immunity from previous infection, the Associated Press reported Monday. Omicron has a deletion atposition69/70of the spike proteinwhich allows it to be tracked through S gene target failure(SGTF)in some PCR tests. Two major BA.2 variant symptoms include dizziness and fatigue, as I wrote for the Deseret News. However, it should be noted both that this is early data and more research is required to confirm these findings. Of those patients admitted to hospital,17had received a booster vaccine, 74 people had 2 doses and 27 people were not vaccinated. SGTF is a useful indicator of the presence of Omicron, because as a rule Delta cases have the S-gene and Omicron cases do not. However, increases in SGTF can give a useful early indication of variant spread. If you have any symptoms of a respiratory infection, and a high temperature or feel unwell, try to stay at home or away from others especially those who are elderly or vulnerable. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. So far there is not enough evidence to draw conclusions about transmissibility, severity or vaccine effectiveness. The UK Health Security Agency (UKHSA) has published the latest variant technical briefing. The UK Health Security Agency (UKHSA) has published analyses of Omicron sub-lineage BA.2. Until we have this evidence, we must exercise the highest level of caution in drawing conclusions about any significant risks to peoples health. Hospital admissions are increasing, and we cannot risk the NHS being overwhelmed. SGTF is not a 100% accurate test for Omicron and results are regularly evaluated against sequencing to ensure they are interpreted correctly. They save lives and prevent serious illness. According to Boden-Albala said, those symptoms may include the following: Fever Chills Fatigue Cough Body aches Shortness of breath Sore throat Additionally, some people may report upper. What are the symptoms of BA.2? As is routine for any new variants under investigation, UKHSAis carrying out laboratory and epidemiological investigations to better understand the properties of this variant. Studiesof households and contactshave found that there is a higher risk of transmission to contacts from an Omicron case, when compared to Delta. UKHSA encourage everyone to continue to follow the most up-to date guidance. Whilst there are insufficient data to quantify either vaccine effectiveness or risk of reinfection in the UK exactly, the observed growth, case distribution and early analyses in both South Africa and the UK are consistent with some loss of immune protection against infection. In the UK, 38 cases of XF have been identified, though none have been seen since mid February. Our continued genomic surveillance allows us to further investigate variants that are growing within the UK. It has since swept the globe, eventually vanquishing other variants including delta. XBB.1.5 remains at very low prevalence in the UK, so estimates of growth are highly uncertain. These are some of the symptoms that you should be looking out for: High temperature. There are insufficient severe cases of Omicronas yetto analyse vaccine effectiveness against hospitalisation, but this is more likely to be sustained, particularly after a booster. It is never too late to come forward for your first dose and its vital that everyone comes forward to get boosted now as we head into the new year. Dont include personal or financial information like your National Insurance number or credit card details. 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. 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. Hospital cases are also rising, but vaccines are still helping to stop many severe. We have now identified cases in the East Midlands, East of England, London, South East and North West. Here is what we know about it. Where individuals are identified as being a possible or probable case of Omicron, their close contacts will be contacted and advised they are required to isolate for 10 days, regardless of whether they have been vaccinated or received a negative COVID-19 test result. We continue to monitor all recombinants closely, routinely through our world-leading genomic surveillance and sequencing capability. This analysis is not an assessment of hospital severity, which will take further time to assess. BA.2, also known as "stealth omicron," is considered a subvariant of omicron. "It's important to know and recognize all of the. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. As is routine for any new variants under investigation,UKHSAis carrying out laboratory and epidemiological investigations to better understand the characteristics of this variant. 8 Research published in April 2022 in The Lancet also found. "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 . Follow the latest self-isolation rules if you develop symptoms wear a mask where required to do so, take regular LFD tests and observe good hand hygiene. In the most recent week of data (specimen dates from 30 November 2021 reported as of 6 December), the number of cases with SGTF has increased to 705. UKHSA analysis shows that the risk of hospital admission for an identified case with Omicron is reduced compared to a case of Delta. However, cases of the variant continue to rise at an extraordinary rate already surpassing the record daily number in the pandemic. UKHSAs most recent variant technical briefing includes examination of a number of recombinant variants which have been identified in the UK, as well as updated epidemiological and genomic analysis of Omicron BA.2. We are continuing to monitor the data closely. Things you can choose to do are: The UK Health Security Agency (UKHSA) has elevated the classification of the COVID-19 variants Omicron BA.4 and Omicron BA.5 to variants of concern (VOCs) on the basis of observed growth. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. 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. The vaccination status was unknown for 6 people, while 8 had received a single dose. In a lot of ways, it's a bad cold, a lot of respiratory symptoms, stuffy nose, coughing, body aches and fatigue," said Dr. Dennis Cunningham, the system medical director of infection control and. Six cases of the SARS-CoV-2 variant known as B.1.1.529 have also been identified in Scotland, with 4 cases in the Lanarkshire area and 2 in the Greater Glasgow and Clyde area. News stories, speeches, letters and notices, Reports, analysis and official statistics, Data, Freedom of Information releases and corporate reports. BA.2 is estimated to account for approximately 93.7% of cases in England, with the highest prevalence in the South East (96.4%) and the lowest in the East Midlands (91.1%). Case rates remain high throughout the UK and we must remain vigilant and take up vaccinations. The original Delta variant remains overwhelmingly dominant in the UK, making up approximately 99.8% of all cases. Dr Jenny Harries, Chief Executive of UKHSA, said: We are continuing our efforts to understand the effect of this variant on transmissibility, severe disease, mortality, antibody response and vaccine efficacy. As with any other coronavirus (COVID-19) variant, the vast majority do not confer any advantage to the virus and die out relatively quickly. While specific symptoms to BA.2 are not yet available, the NHS lists the main symptoms for Covid-19 as: a high temperature a new, continuous cough a. 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. A further 3 cases have been identified in Scotland, bringing the total to 13. Until the week beginning 23 November 2021, the weekly count of cases with SGTF was routinely less than 150, making up less than 0.1% of all cases. This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. For some more vulnerable a third dose is available. But the latest data suggests this extra protection starts to wane more rapidly, being about 15 to 25% lower from 10 weeks after the booster dose. Any variants showing evidence of spread are rapidly assessed. 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. 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. 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. How are Covid rules changing across UK schools? Symptoms of BA.2 appear to largely mirror those of the original version of the omicron variant: an upper respiratory illness that causes sore throat, cough, congestion, headache and fatigue. The individual is no longer in the UK, but UKHSA is carrying out targeted testing at locations where the positive case visited when they were likely to have been infectious. Omicron sublineages BQ.1 and XBB have been given UKHSA variant designations to facilitate continued studies. 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. Get vaccinated and, for those eligible, come forward for your third or booster dose as appropriate as soon as you are called. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. The COVID Omicron sub-variant BA.2, informally dubbed the "Stealth Omicron" variant, is able to reinfect people who have already had Omicron, a new study suggests. 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. ; The incubation time (time to onset of symptoms) is a bit shorter: 3 days. Currently, the Omicron variant has BA.1, BA.2, BA.3, and B.1.1.529 sub-variants, of which the BA.1 was dominant a few months before, and scientists have recently warned about the BA.2 sub-variant . According to Denmark's Statens Serum Institut (SSI), BA.2 infections rose to account for about half of the country's reported Covid cases in January. The team at ZOE, a study that tracks symptoms . As we cautiously return to Plan A, I encourage you to give yourself and your loved ones the best protection possible and Get Boosted Now. There are indications of a small rise in children admitted to hospital, but these early signals need further investigations before we can draw any conclusions about whether Omicron causes more severe illness in children. The most commonly-reported symptoms with the original Omicron variant were cough, fatigue, headache, congestion, and runny nose. Where individuals are identified as being a possible or probable case, their close contacts will be contacted and advised to isolate for 10 days and to take a test. More recent data on Omicron cases is published regularly here. Vaccine effectiveness (VE) against Omicron has again been updated in this weeks briefing. The latest Omicron SARS-CoV-2 subvariant, which scientists have labeled BA.2.12.1, is on track to become the most virulent strain in the United States currently. Runny or congested nose Feeling fatigued Headache New, continuous cough Shortness of breath or difficulty breathing Muscle or body aches New loss of a sense of taste or smell Sore throat Nausea or vomiting Diarrhoea They advise that if you develop one or more of these symptoms you should take a Covid test as soon as possible. Lower back pain. We will continue to monitor this situation closely and recommend appropriate public health measures if needed. Whilst Omicron BA.4 and BA.5 are in the early stages of growth in the UK, analysis of the available data suggests that they are likely to have a growth advantage over the currently-dominant Omicron BA.2 variant. In some countries, BA.2 accounts for more than half of sequenced Omicron cases, it adds. Neither BQ.1 nor XBB have been designated as variants of concern and UKHSA is monitoring the situation closely, as always. Since then, several sub-variants of Omicron surfaced, including BA.2, BA.3, BA.4, and BA.5. However, vaccinated people are still less likely to get infected than unvaccinated individuals, and they are also less likely to pass it on. With the original version of the omicron variant, which swept across the U.S. at a dizzying speed last winter, the loss of taste and smell was not as common as with the earlier alpha and delta variants. 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. UKHSAis acting to get scientific information available as quickly as possible in order to inform the right balance of interventions to prevent transmission and protect lives. UKHSA Chief Medical Advisor, Dr Susan Hopkins said: It is increasingly evident that Omicron is highly infectious and there is emerging laboratory and early clinical evidence to suggest that both vaccine-acquired and naturally acquired immunity against infection is reduced for this variant. Over 40% of hospital admissions were in London. BA.3 shares most of its mutations with BA.1 and BA.2 except for one. 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. Neither have currently been designated as variants of concern. 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. The symptoms of omicron BA.2.75 are mostly flu-like and may last more than 4-5 days. There are simple things you can do in your daily life that will help reduce the spread of COVID-19 and other respiratory infections and protect those at highest risk. It contains updated analysis on Omicron hospitalisation risk, vaccine efficacy against symptomatic disease from Omicron, and the COVID-19 reinfection rate. Recent studies suggest that BA.2 has a. BA.2 is believed to be far more contagious than the earlier Omicron strain, and was blamed for a fresh surge in Denmark. However, it should serve as objective evidence that this pandemic is not over. So how worried should we be about this emerging variant? Our data shows that getting the booster vaccine is more effective against this variant than 2 doses alone. Booster doses also increase the protection against symptomatic and asymptomatic infection which will reduce transmission in the population. The individual tested positive after travel to the UK and is linked to travel to Southern Africa. Getty Images BA.2 was. The v Xi Jinping is unveiling a new deputy - why it matters, Bakhmut attacks still being repelled, says Ukraine, Saving Private Ryan actor Tom Sizemore dies at 61, The children left behind in Cuba's mass exodus, Snow, Fire and Lights: Photos of the Week. Its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. Data on this wont be available for several weeks. There are differences in the populations that have received different vaccines. ; An increase in new cases is being . As of 30 November 2021, there are 22 confirmed cases of Omicron (B.1.1.529), identified through sequencing or genotyping in England. Dr Meera Chand, Director of Clinical and Emerging Infections at UKHSA, said: The reclassification of these variants as variants of concern reflects emerging evidence on the growth of BA.4 and BA.5 internationally and in the UK. Runny nose (especially in combination with loss of smell) A runny nose is a universal sign of cold, flu and now COVID-19. The pace of sharing sequences by India is very slow, median days from collection to deposition is 69 days according to GISAID. "We must remain vigilant and take up vaccinations. Latest updates on SARS-CoV-2 variants detected in the UK. The UK Health Security Agency (UKHSA) can confirm that 10 people have been hospitalised with the Omicron variant in England; the individuals were diagnosed on or before admission. 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. Dont worry we wont send you spam or share your email address with anyone. New sub-lineages within Delta continue to be identified. The UK has been hard-hit by a further spike in Covid-19 cases in recent weeks, with infections being driven by a sub-lineage of the Omicron variant known as BA.2 or "Stealth Omicron". UKHSA has also published a breakdown of confirmed Omicron cases and SGTF cases by local authority. All age groups are affected, including the 75s and over, who are due a spring booster jab to top up protection. Our advanced sequencing capabilities enable us to find variants and take rapid action to limit onward spread. A total 637 cases of XE a recombinant of Omicron BA.1 and BA.2 have been confirmed in the UK so far. A NEW Covid-19 Omicron sub-variant is spreading across Ireland and is the most infectious strain yet. Work is underway to identify any links to travel. 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. The assessment suggests that Omicron is displaying a significant growth advantage over Delta, meaning that it is likely to outcompete Delta in the UK and become the dominant variant. Fatigue. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. The early observations for 2 doses of AstraZeneca are particularly likely to be unreliable as they are based on small numbers and are likely to reflect an older population and a population with more co-morbidities than those given the Pfizer vaccine. It is one for the scientists to watch, rather than for the public to be alarmed about at this stage. 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".
