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. Trends in SGTF over and time are however affected by the coverage of laboratories contributing to this surveillance data. BA2 Variant is overtaking Delta and Omicron Cases at rapid speed. 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 . After 2 doses, vaccine effectiveness was 9% and 13% respectively for BA.1 and BA.2, after 25+ weeks. Those mutations are shared with the original omicron, but BA.2 also has . 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. UKHSA has also published a breakdown of confirmed Omicron cases and SGTF cases by local authority. What is the Covid BA.2 variant? Symptoms of Omicron sub-variant This analysis is preliminary and highly uncertain because of the small numbers of Omicron cases currently in hospital, inability to effectively measure all previous infections and the limited spread of Omicron into older age groups. The designation was made on the basis of increasing numbers of BA.2 sequences identified both domestically and internationally. 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. BA.2.75.2 Variant: What We Know About 'Centaurus,' Vaccines | Time Our exceptional vaccine rollout means the number of people severely affected by COVID-19 is low, and the UKs innovation and research has discovered life-saving treatments for those most at risk from COVID-19. Infection rate corrected to one million infections a day. While BA.1 and BA.2 are similar, they are 20 mutations apart. According to the COVID Symptom Study, the five most common symptoms are the same: Runny nose, headache, fatigue, sneezing and sore throat. What to know about omicron BA.2 variant symptoms - NBC News Scratchy throat. We have also learnt that BA.2 has a slightly higher secondary attack rate than BA.1 in households. A recombinant variant occurs when an individual becomes infected with 2 or more variants at the same time, resulting in a mixing of their genetic material within the patients body. BQ.1 (V-22OCT-01) is a BA.5 sub-lineage which has been designated on the basis of rapid growth. The UK Health Security Agency (UKHSA) has published variant technical briefing 37. Currently, approximately half of all tests conducted in the UK are able to detect SGTF. An important question is whether BA.2 or BA.3 will become a new dominating "variant of concern". If you have symptoms take a PCR test and isolate at home until you receive a negative result. Those aged 18 to 39 should wait to be called. The individuals who have tested positive and their contacts have been asked to self-isolate. These include a high temperature, a new. Dr Meera Chand, Director of Clinical and Emerging Infections, UKHSA, said: Through our genomic surveillance we continue to see evolution of variants in the Omicron family. What is Stealth Omicron? Symptoms of the Covid variant responsible for 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. UKHSAis carrying out targeted testing at locations where the positive cases were likely to be infectious. The worst symptom is a "throat on fire," said University of California, San Francisco's Dr. Peter Chin-Hong. A total 637 cases of XE a recombinant of Omicron BA.1 and BA.2 have been confirmed in the UK so far. 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 focused contact tracing. Please make sure to wear a mask in line with government guidance, including on public transport and in shops, to help break the chains of transmission and slow the spread of this new variant. Its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. The World Health Organization has been monitoring SARS-CoV-2 (the virus that causes Covid-19) since January 2020, during which time the variant Omicron has been identified, which is technically known as BA.1 or B.1.1.529.The WHO is now monitoring a sub-variant of Omicron, known as BA.2, which has been described as "stealth Omicron," because it has genetic mutations that potentially make it . This is very encouraging. [92] Reactions [ edit] Vaccine producers [ edit] Well send you a link to a feedback form. 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. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. For example, there are still a small number of cases of other variants, such as Alpha, in the UK which would also result in S-gene dropout or there is a lower amount of virus present in the sample where S-gene dropout cannot be confirmed. However, one must note, these are only early stage symptoms. 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. 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. A runny nose, gastrointestinal issues, headache and a skin rash are other common signs and symptoms. 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. Our continued genomic surveillance allows us to further investigate variants that are growing within the UK. Getty Images BA.2 was. Recent studies suggest that BA.2 has a. Although hospitalisations and deaths remain low, cases are still high in some areas and some age groups so its important that we continue to act cautiously as restrictions are lifted. The proportion of test results displaying SGTF has been very low in recent months but an increase has been observed in the past week. The UK Health Security Agency (UKHSA) has identified 75 further cases of COVID-19 with mutations consistent with B.1.1.529 in England, in addition to the previous 29 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529. The full document and underlying data is available on GOV.UK. Effectiveness of first and second COVID19 mRNA vaccine monovalent SARS-CoV-2 Omicron variant - Wikipedia The total number of confirmed cases in England is now 22. Continue to exercise caution. 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 . We will continue to closely analyse all available biological, epidemiological and genomic evidence for any SARS-CoV-2 variant in the UK or internationally. 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. The team at ZOE, a study that tracks symptoms . More evidence is needed to know whether this is due to changes in the virus behaviour or to epidemiological conditions. New Covid Omicron BA.2 variant - Two unusual symptoms to watch for Dr Meera Chand, COVID-19 Incident Director at UKHSA, said: It is the nature of viruses to evolve and mutate, so its to be expected that we will continue to see new variants emerge as the pandemic goes on. Covid 4th wave: New BA.2 variant can impact stomach and intestine, say These people are spread around the country and are a mix of age ranges between 18 to 85 years the majority had received 2 doses of vaccination. If you have any symptoms, take a test. The five most common symptoms of Omicron are: runny nose;.

Dont include personal or financial information like your National Insurance number or credit card details. Following the change in JCVI advice today, 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. This analysis shows you are up to 8 times more likely to end up in hospital as a result of COVID-19 if you are unvaccinated. The updated risk assessment includes indicators for infection severity in both adults and children. The UK Health Security Agency (UKHSA) has identified 7 further cases of COVID-19 with mutations consistent with B.1.1.529 in England, in addition to the previous 22 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529. The best way that you can protect yourself is to come forward for your first 2 doses of vaccine, or your booster jab and do everything you can to stop onward transmission of the infection. It contains epidemiological data and updated analysis of COVID-19 variants currently circulating in the UK. 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. More recent data on Omicron cases is published regularly here. The UK Health Security Agency (UKHSA) has published the latest variant technical briefing. An individual with Omicron is estimated to be between 31 and 45% less likely to attend A&E compared to Delta, and 50 to 70% less likely to be admitted to hospital. What are the symptoms of BA.2? Telltale symptoms for Deltacron, Omicron, and the BA.2 Covid variants 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. We now know that BA.2 has an increased growth rate which can be seen in all regions in England. Current guidance from NHS England is that the main symptoms of Covid continue to be a high temperature, a new continuous cough, a loss or change to your sense. 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. Omicron BA.4 and Omicron BA.5 were designated as variants of concern on 18 May on the basis of an apparent growth advantage over the previously-dominant Omicron BA.2 variant. BA.2 continues to demonstrate a substantial growth advantage. Read about our approach to external linking.

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 analysis looked at 581 people with confirmed Omicron. The UK Health Security Agency (UKHSA) has published the latest Variant Technical Briefing. It is not unexpected to see new lineages and continued investigation is a normal part of the surveillance of an infectious disease. 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). The Philippines' Department of Health (DOH) said the BA.2 sub-lineage was already prevalent in samples it received at the end of January. None of the cases to date is known to have been hospitalised or died. All 3 subvariants have spike protein mutations of L452 and elude immunity from prior BA1 infection. It appears to have a growth advantage compared to the version of Omicron, BA.1, that has swept the globe. In the UK, 38 cases of XF have been identified, though none have been seen since mid February. SGTF is not a 100% accurate test for Omicron and results are regularly evaluated against sequencing to ensure they are interpreted correctly. 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. BA.2, also known as "stealth omicron," is considered a subvariant of omicron. It is critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. 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 . Fourteen people are reported to have died within 28 days of an Omicron diagnosis, ranging in age from 52 to 96 years old. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. Under the new system, the variant of concern (VOC) label will be assigned to variants which are currently emerging or circulating, and which the following characteristics can be confirmed or predicted: 1. UKHSAreleases weekly updates on the number of confirmed new cases of variants of concern and variants under investigation identified in the UK. Hospital admissions are increasing, and we cannot risk the NHS being overwhelmed. Here is what we know about it. . Its not too late to catch up if youve missed boosters, or even first doses so please take your recommended vaccines. The BA.2 subvariant of the COVID-19 virus is now the dominant coronavirus strain in the world, and while health officials are saying the subvariant acts like the original omicron version of the . The individuals that have tested positive and their contacts are all isolating. Susan Hopkins, Chief Medical Adviser at UKHSA, said: The latest set of analysis is in keeping with the encouraging signs we have already seen. However, it should serve as objective evidence that this pandemic is not over. Neither have currently been designated as variants of concern. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. Sajid Javid, Secretary of State for Health and Social Care, said: Todays new data shows how important booster jabs are to protect us against this variant. There will be no other categorisation of variants, including no variant under investigation (VUI) category. Two variants, CH.1.1 and XBB.1.5, appear to have a growth advantage in the UK. By the summer of 2022, the BA.5 variant was the most dominant strain in the US. This analysis excludes individuals with confirmed previous COVID-19 infection. Approximately half of PCR tests in the UK are able to detect SGTF. Dr Meera Chand, Director of Clinical and Emerging Infection at UKHSA, said: It is not unexpected to see new variants of SARS-CoV-2 emerge. 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. Studies have already shown that this virus travels to different parts of the body, therefore gut-related issues are. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. The highly transmissible Omicron variant now accounts for half of the world's infections. We constantly assess the genetic diversity within the known variants of concern (VOCs) to inform our ongoing public health response to the pandemic. UKHSAs most recent variant technical briefing can be found on GOV.UK. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. What are the symptoms of BA.2? Booster doses also increase the protection against symptomatic and asymptomatic infection which will reduce transmission in the population. UKHSAs latest analysis suggests that Omicron BA.5 is growing 35.1% faster than Omicron BA.2, while Omicron BA.4 is growing approximately 19.1% faster. It is important that everyone ensures that they are up to date with vaccinations offered as they remain our best form of defence against severe illness. 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.

This will include analysing live samples of the new variant in our laboratories to investigate properties including its response to current vaccines. However, cases of the variant continue to rise at an extraordinary rate already surpassing the record daily number in the pandemic. 1. Of these, XD and XF are recombinants of Delta and Omicron BA.1, while XE is a recombinant of Omicron BA.1 and BA.2. Please make sure to wear a mask in line with government guidance, including on public transport and in shops, to help break the chains of transmission and slow the spread of this new variant. What are the five main Omicron symptoms? - Open Access Government Further information is also available in the latest variant technical briefing. 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. One case is located in Camden, London, and one case is located in Wandsworth, London. As is routine for any new variants under investigation, UKHSAis carrying out laboratory and epidemiological investigations to better understand the properties of this variant. Now more countries, particularly in Asia and Europe, are reporting an increase in cases driven by BA.2. 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. Following the change in Joint Committee on Vaccination and Immunisation (JCVI) advice yesterday, a booster dose for everyone over 18 years is now recommended at a minimum of 3 months from your last primary course jab. I urge you to come forward as soon as youre eligible to help keep yourself and your loved ones safe. The variant technical briefing also includes updated analysis on Omicron BA.2, currently the dominant variant in the UK. Vaccine effectiveness against severe disease from Omicron is not yet known but is expected to be significantly higher than protection against symptomatic disease. Genome sequencing among the states is not always fair. pic.twitter.com/ESQupxUet4. There is insufficient data to make any assessment of protection against severe disease, or to assess the severity of illness caused by Omicron. What we know is that it is certainly growing as a proportion of overall cases in the UK. We also use cookies set by other sites to help us deliver content from their services. Even if a smaller proportion of these individuals require hospitalisation, these are still large numbers of people requiring hospital care and pressures on the NHS will increase. 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. Previous variants of concern which no longer meet the criteria will be redesignated. If the growth rate and doubling time continue at the rate we have seen in the last 2 weeks, we expect to see at least 50% of coronavirus (COVID-19) cases to be caused by Omicron variant in the next 2 to 4 weeks. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. We urge these people in particular to get up-to-date.
