";s:4:"text";s:28512:"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. Can Nigeria's election result be overturned? The BBC is not responsible for the content of external sites. We have now identified cases in the East Midlands, East of England, London, South East and North West. News stories, speeches, letters and notices, Reports, analysis and official statistics, Data, Freedom of Information releases and corporate reports. There is further data showing that effectiveness against symptomatic disease is significantly lower compared to the Delta variant, and wanes more quickly. 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. BA.2 Symptoms Not That Different From Omicron, Delta. The UK Health Security Agency (UKHSA) has published a new variant technical briefing containing an updated Omicron risk assessment, alongside analysis on vaccine efficacy, sub-lineages and symptoms. A detrimental change in biological properties (changes in transmissibility, severity or immune evasion) compared to the current dominant variant. The symptoms of omicron BA.2.75 are mostly flu-like and may last more than 4-5 days. We will continue to monitor this situation closely and recommend appropriate public health measures if needed. . The two most reported symptom of patients infected by the Stealth Omicron variant is -dizziness and fatigue. Wear a mask in crowded spaces and, when meeting people indoors, open windows and doors to ventilate the room. 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. 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. Teams nationally and locally are working at pace to identify and trace all close contacts of every Omicron case. 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. They also say that Omicron symptoms are typically mild, and herd immunity is at . A separate UK study also found higher transmissibility for BA.2 compared to BA.1. UKHSA has performed an initial laboratory evaluation of the current lateral flow devices (LFDs) for COVID-19 in current use in the UK. 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. Health and Social Care Secretary, Sajid Javid, said: We are learning to live with this virus and thanks to our world-leading surveillance system we can rapidly detect and carefully monitor any genetic changes to COVID-19. Since then, the Centers for Disease Control and Prevention (CDC) has classified two subvariants, BA.1.1 and BA.2. The designation was made on the basis of increasing numbers of BA.2 sequences identified both domestically and internationally. COVID-19 has not gone away, so it is also vitally important that people continue to follow the guidance. We have also learnt that BA.2 has a slightly higher secondary attack rate than BA.1 in households. Take a vaccine to protect yourself against COVID-19. 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. In some places, growth in recorded cases of the sub-variant has been sharp. A major ailment is not to be expected for the age group 20-50 years. The first sequences were submitted from the Philippines, and most samples have been uploaded from Denmark (6,411). 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. 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. A runny nose, gastrointestinal. Currently there are 18 UK samples in GISAID, out of a global total of 1,086; 639 samples have been uploaded from Singapore, and it is thought that XBB may be a factor in the recent spike in cases there. What is the stealth omicron, or BA.2, variant? Our continued genomic surveillance allows us to further investigate variants that are growing within the UK. Scientists in the UK and abroad are closely monitoring BA.2, a sub-variant of Omicron. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. BA.3 shares most of its mutations with BA.1 and BA.2 except for one. 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. We should all continue to test regularly with LFDs and take a PCR test if symptoms develop. BQ.1 (V-22OCT-01) is a BA.5 sub-lineage which has been designated on the basis of rapid growth. Of these, 20 were in England, 3 in Scotland and 1 in Wales. There are small numbers of cases in the UK and this designation is intended to allow investigation into the specific properties of this variant. 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. We will continue to closely analyse all available biological, epidemiological and genomic evidence for any SARS-CoV-2 variant in the UK or internationally. This analysis is not an assessment of hospital severity, which will take further time to assess. 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 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. But it is worth noting that Denmark has seen similar trends in terms of hospital admissions and intensive care as the UK has, suggesting BA.2 does not mark a sea-change in severity. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. If you have any symptoms, take a test. 1. Whilst the impact of these variants is uncertain, the variant classification system aims to identify potential risk as early as possible. This is more promising data which reinforces just how important vaccines are. The B.1.1.529variant includes a large number of spike protein mutations as well as mutations in other parts of the viral genome. As with any other coronavirus (COVID-19) variant, the vast majority do not confer any advantage to the virus and die out relatively quickly. Based on the reports from doctors treating the Covid variant and patients battling. 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. BA.2, also coined as the "stealth" variant, is a relative of Omicron's original variant, BA.1, which tore through the Australian community over Christmas and the New Year period. UKHSA is updating its variant classification system to give a clearer indication of which variants have significant changes compared to the current dominant variant. In this analysis, the risk of hospitalisation is lower for Omicron cases with symptomatic or asymptomatic infection after 2 and 3 doses of vaccine, with an 81% (95% confidence interval 77 to 85%) reduction in the risk of hospitalisation after 3 doses compared to unvaccinated Omicron cases. 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. Genomes have now been uploaded from South Africa, Botswana and Hong Kong but the extent of spread is not yet determined. As with previous variants, experts believe vaccines will continue to be highly effective against severe illness, hospitalisation, and death. Once again, we urge everyone who is able to get a booster jab to come forward and do so. While prevalence remains high, make sure to wear your mask in indoor settings and take a lateral flow test before meeting others. 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. Everybody who is contacted or has symptoms should take a PCR test as soon as possible, even if they have received a positive COVID-19 PCR test within the last 90 days. The risk of catching or passing on COVID-19 is greatest when someone who is infected is physically close to, or sharing an enclosed or poorly ventilated space with, other people. One of the most common symptoms of the Omicron subvariant BA.2 is nausea. 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. Fourteen people are reported to have died within 28 days of an Omicron diagnosis, ranging in age from 52 to 96 years old. Omicron continues to grow faster than Delta, with an increased risk of transmission, particularly in contacts outside of the household. 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. What we know is that it is certainly growing as a proportion of overall cases in the UK. We should all continue to test regularly with LFDs [lateral flow devices] and take a PCR [polymerase chain reaction] test if symptoms develop.". 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. The Omicron BA.2 subvariant is fast becoming the dominant strain of COVID-19, with symptoms similar to previous strains of the virus. More recent data on Omicron cases is published regularly here. So far, vaccination means that the rise in cases is not translating to a rise in severe illness and deaths. The majority of these cases are located in London and the South East. There are no confirmed cases in Northern Ireland. 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. Dr Meera Chand, UKHSA Director of Clinical an Emerging Infection, said: We continue to monitor the emergence of new variants and give them variant designations if they are sufficiently distinct to warrant separate epidemiological and laboratory assessment. 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. India is another country where BA.2 is rapidly replacing the Delta and Omicron BA.1 variant, according to molecular biologist Bijaya Dhakal. Get vaccinated and, for those eligible, come forward for your third or booster dose as appropriate as soon as you are called. This is still a very small number of cases but is being investigated carefully to understand whether it is related to travel, any other variant or whether there is evidence of spread of Omicron beginning in the community. 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. 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. The genome of VUI-21OCT-01 does not have many mutations compared to Delta. It was designated a variant of concern (VOC) on Saturday 27 November. The increasing prevalence of Omicron BA.4 and BA.5 is likely to be a factor in the recent increase in cases seen in the UK and elsewhere, though there is currently no evidence that Omicron BA.4 and BA.5 cause more severe illness than previous variants. The UK Health Security Agency (UKHSA) has published variant technical briefing 37. March 31, 2022. 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. 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. Evidence continues to show that Omicron is transmitting more rapidly than the dominant Delta variant. Therefore, although early suggestions are that individuals may be less likely to require hospitalisation, many more people are likely to become infected. ROCHESTER, Minn. The World Health Organization designated COVID-19 variant B.1.1.529, named omicron, a "variant of concern" on Nov. 26, 2021, and the first confirmed case in the U.S. was on Dec. 1, 2021. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. These changes will take effect as of 1 April 2022 and will be reflected in full in future technical briefings. Well send you a link to a feedback form. How are Covid rules changing across UK schools? You can change your cookie settings at any time. 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. One case is located in Camden, London, and one case is located in Wandsworth, London. There are differences in the populations that have received different vaccines. Two variants, CH.1.1 and XBB.1.5, appear to have a growth advantage in the UK. Until we have this evidence, we must exercise the highest level of caution in drawing conclusions about any significant risks to peoples health. The variant technical briefing also includes updated analysis on Omicron BA.2, currently the dominant variant in the UK. The UK Health Security Agency (UKHSA) has published the latest Variant Technical Briefing. Updated analysisshows theadditional incremental benefit from each vaccine exposureincluding for boosters, even in those who have had prior infection. These include a high temperature, a new. 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. 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. UKHSAs new analysis examines 3 recombinants, known as XF, XE, and XD. A NEW Covid-19 Omicron sub-variant is spreading across Ireland and is the most infectious strain yet. 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. 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. The areas with the largest number of confirmed cases are London (146) and the South East (97). That contrasts to Denmark, where it has become dominant. Since the middle of February, this growth rate has settled at approximately 75% higher than other circulating Omicron lineages in England. The total number of confirmed cases in England is now 22. The UK Health Security Agency (UKHSA) is reminding people to ensure their COVID-19 vaccinations are up to date and to continue following COVID-safe behaviours, as latest technical data indicates BA.4 and BA.5 have become dominant in the UK and are driving the recent increase in infections. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. BA.2, also known as "stealth omicron," is considered a subvariant of omicron. 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. This is to be expected and UKHSA is monitoring the situation closely. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. XD has not been identified in the UK to date, though 49 cases have been reported to global databases, the majority of these are in France. UKHSA Chief Executive, Jenny Harries said: I want to thank everyone who has been working globally and locally to help us act incredibly quickly in response to the Omicron variant. Read about our approach to external linking. Analyses of sequenced SGTF samples has indicated that until mid-November, more than 99% of these were Delta cases. Twoto4 weeks after a booster dose, vaccine effectiveness ranged from around 65 to 75%, dropping to 55 to 70% at 5 to 9 weeks and 40 to 50% from 10+ weeks after the booster. UKHSA are continuing to monitor data on the BA.2 sub-lineage closely. 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. 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. It is not clear where BA.2 originated, but it was first detected in the Philippines in November. There is now high confidence that the Omicron variant causes low severity of disease in adults. No cases have been identified in the UK. Neutralisation studies are currently being undertaken at the University of Oxford. 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 Over 40% of hospital admissions were in London. UKHSA continues to monitor and study variants of SARS-CoV-2 closely and is working with academic partners to rapidly assess the significance of the lineages BA.4 and BA.5. Work is underway to identify any links to travel to Southern Africa. 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. The UK Health Security Agency (UKHSA) has released variant technical briefing 50. Since then, several sub-variants of Omicron surfaced, including BA.2, BA.3, BA.4, and BA.5. One individual diagnosed in hospital has sadly died. Data continues to show COVID-19 poses a very low health risk to children and infants. Many people who have Omicron say it feels like a common cold, and here are the 8 early warning signs you need to look out for. Analysis from routine contact tracing data indicates that transmission is likely to be higher among contacts of BA.2 cases in households (13.4%) than those for contacts of other Omicron cases(10.3%) in the period 27 December 2021 to 11 January 2022. It is testament to the diligence and scientific expertise of my colleagues at UKHSA, and the genomic sequencing capacity developed through the pandemic, that this new variant has been identified and analysed so quickly. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. We now know that BA.2 has an increased growth rate which can be seen in all regions in England. As of January 10 2022, 53 sequences of the BA.2 sub-lineage of Omicron had been identified in the United Kingdom. For the first time, this data includes analysis on vaccine effectiveness 15+ weeks after the booster dose. More detail will be available in UKHSAs regular variant technical briefings. Dr Susan Hopkins, Chief Medical Adviser at UKHSA, said: Hospitalisations always lag a few weeks behind infections, therefore it isnt surprising that we have started to see people being admitted to hospital with the Omicron variant. [92] Reactions [ edit] Vaccine producers [ edit] Working alongside Cambridge University MRC Biostatistics unit, UKHSA analysed 528,176 Omicron cases and 573,012 Delta cases between 22 November and 26 December to assess the risk of hospitalisation in England after testing positive for Omicron. 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. Here is what we know about it. Early analyses suggest an increased growth rate compared to BA.1, however, growth rates have a low level of certainty early in the emergence of a variant and further analysis is needed. Cases are currently very high in the UK, and even a relatively low proportion requiring hospitalisation could result in a significant number of people becoming seriously ill. 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. The study also showed evidence to suggest that the BA.2 sub-variant is better able to evade vaccines. People aged 75 and over remain at particular risk of severe disease if they are not up to date with their vaccinations. This analysis excludes individuals with confirmed previous COVID-19 infection. This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. Lower back pain. Overall, the original Omicron lineage, BA.1, is dominant in the UK and the proportion of BA.2 cases is currently low. 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. As of 30 November 2021, there are 22 confirmed cases of Omicron (B.1.1.529), identified through sequencing or genotyping in England. In severe cases, the SpO2 Level may also decrease. There is insufficient data to make any assessment of protection against severe disease, or to assess the severity of illness caused by Omicron. 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. So far there is not enough evidence to draw conclusions about transmissibility, severity or vaccine effectiveness. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. 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 updated risk assessment includes indicators for infection severity in both adults and children. This increased to 63% for BA.1 and 70% for BA.2 at 2 weeks following a third vaccine. The risk assessment also suggests that Omicron displays a reduction in protection offered by having had a previous infection or vaccination. A total 637 cases of XE a recombinant of Omicron BA.1 and BA.2 have been confirmed in the UK so far. Because of a quirk in how it shows up in test results, we can see the numbers of suspected BA.2 doubled in the week up to 24 January. UKHSAwill continue to carry out laboratory and epidemiological investigations to better understand the characteristics of this variant. The data once again shows that coming forward for your jab, particularly your third dose, is the best way of protecting yourself and others against infection and severe disease. It showed that the AstraZeneca and Pfizer-BioNTech vaccines provided much lower levels of protection against symptomatic infection compared to the protection that they provide against Delta. Omicron sublineages BQ.1 and XBB have been given UKHSA variant designations to facilitate continued studies. B.1.1.529 has a large number of mutations in the gene coding for the spike protein, and also in other parts of the viral genome. As is routine for any new variants under investigation,UKHSAis carrying out laboratory and epidemiological investigations to better understand the characteristics of this variant. Latest updates on SARS-CoV-2 variants detected in the UK. Neither have currently been designated as variants of concern. We urge these people in particular to get up-to-date. Runny nose (especially in combination with loss of smell) A runny nose is a universal sign of cold, flu and now COVID-19. However, with the spread of BA.4 and BA.5, that symptom seems to have returned, some doctors note. There have been recent reports of people who experience symptoms like those of viral meningitis, an inflammation of the brain and spinal cord membranes. 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. 34 Subsequent studies that were performed in periods when a mix of BA.1, BA.2, BA.4, and BA.5 viruses circulated have reported low effectiveness of a second booster against . Where variant information was available, the majority of intensive care unit (ICU) admissions from 24 November 2021 to 19 January 2022 had Delta infections. The v The pace of sharing sequences by India is very slow, median days from collection to deposition is 69 days according to GISAID. Two-thirds with Omicron say they had Covid before. However, increases in SGTF can give a useful early indication of variant spread. Aside from all of the usual COVID symptoms, like a dry cough, a scratchy throat, fatigue, and muscle aches, the Stealth variant is thought to cause a few other distinct issues. 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. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. 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. The original Delta variant remains overwhelmingly dominant in the UK, making up approximately 99.8% of all cases. What are the most common symptoms of Omicron BA.2? 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 . 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.
