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. 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. 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. UKHSA designated variant B.1.1.529 as a variant under investigation (VUI) on Thursday 25 November. It is one for the scientists to watch, rather than for the public to be alarmed about at this stage. This sub-lineage, which was designated by Pangolin on 6 December 2021, does not have the spike gene deletion at 69-70 that causes S-gene target failure (SGTF), which has previously been used as a proxy to detect cases of Omicron. It is critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. However, one must note, these are only early stage symptoms. 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. In some places, growth in recorded cases of the sub-variant has been sharp. Health and Social Care Secretary Sajid Javid said: This data is yet more evidence that vaccines remain our best line of defence against COVID-19. 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. India is another country where BA.2 is rapidly replacing the Delta and Omicron BA.1 variant, according to molecular biologist Bijaya Dhakal. 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). 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. Hospital admissions are increasing, and we cannot risk the NHS being overwhelmed. 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 shows that getting the booster vaccine is more effective against this variant than 2 doses alone. 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. There will be no other categorisation of variants, including no variant under investigation (VUI) category. 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. 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. 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. While signs remain encouraging on Omicrons severity compared with Delta, the high levels of community transmission continue and may cause pressures on health services. The risk assessment conducted by UKHSA together with academic partners found that CH.1.1 and XBB.1.5 are currently the variants most likely to take over from BQ.1 as the next dominant variant in the UK, unless further novel variants arise. The individual tested positive after travel to the UK and is linked to travel to Southern Africa. 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. Fatigue. For the first time, this data includes analysis on vaccine effectiveness 15+ weeks after the booster dose. UKHSAis carrying out targeted testing at locations where the positive cases were likely to be infectious. 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. The UK Health Security Agency (UKHSA) has published variant technical briefing 37. Headache. Now more countries, particularly in Asia and Europe, are reporting an increase in cases driven by BA.2. 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. The UK Health Security Agency (UKHSA) estimates that if Omicron continues to grow at the present rate, the variantwill become the dominant strain, accounting for more than 50% of all COVID-19 infections in the UK by mid-December. The total number of confirmed cases in England is now 5. To date, there have been 426 cases of Omicron BA.2 confirmed by Whole Genome Sequencing (WGS), with the earliest dated 6 December 2021. BA.1 accounts for most of the cases. This is more promising data which reinforces just how important vaccines are. 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. The UK Health Security Agency (UKHSA) has released variant technical briefing 41. It contains updated analysis on Omicron hospitalisation risk, vaccine efficacy against symptomatic disease from Omicron, and the COVID-19 reinfection rate. While BA.2 appears to be more transmissible than previous variants, there is no data yet to suggest that it is any more severe. Fourteen people are reported to have died within 28 days of an Omicron diagnosis, ranging in age from 52 to 96 years old. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. Of these, 20 were in England, 3 in Scotland and 1 in Wales. The v 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. More investigation is required to fully determine the extent of these mutations impact. How are Covid rules changing across UK schools? Apart from dizziness and fatigue, some other signs of BA.2 Omicron Variants include: Fever and body aches Loss of taste Nausea or Vomiting Abdominal pain Fever Extreme fatigue Coughing Sore throat Muscular fatigue Elevated heart rate Breathless in severe cases readmore End of Story BA.2 omicron symptoms According to the CDC, the symptoms of Covid-19, including BA.2, are: Fever or chills Cough Shortness of breath or difficulty breathing Fatigue Muscle or body. The BA.2 variant is a sibling of the BA.1, which swept across the country over Christmas. 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. Recent studies suggest that BA.2 has a. There is further data showing that effectiveness against symptomatic disease is significantly lower compared to the Delta variant, and wanes more quickly. UKHSAs new analysis examines 3 recombinants, known as XF, XE, and XD. New studies are being undertaken to assess this further. Studies of contacts show that Omicron is transmitting more effectively than Delta. 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. Previous updates were published by Public Health England. 1 case has been identified in Wales. The Delta variant, for example, comprises 200 different sub-variants. There is still uncertainty around the significance of the changes to the viral genome, and further analyses will now be undertaken. 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. There can be several reasons for growth advantage, but in the case of BA.4 and BA.5, laboratory data suggests a degree of immune escape which is likely to contribute. BA.2, also known as "stealth omicron," is considered a subvariant of omicron. The worst symptom is a "throat on fire," said University of California, San Francisco's Dr. Peter Chin-Hong. 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. This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. 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. One case is located in Camden, London, and one case is located in Wandsworth, London. XBB.1.5 remains at very low prevalence in the UK, so estimates of growth are highly uncertain. New sub-lineages within Delta continue to be identified. UKHSAs latest National flu and COVID-19 surveillance report indicates that the increase in COVID-19 case rates and hospitalisations continues to show signs of slowing. The same happened with Omicron, which includes the lineages BA.1, BA.2, BA.3 and B.1.1.529. A BA2 variant's symptoms are similar to those of Omicron. 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. Experts say BA.2 has extensive mutations and is about 40 percent more infectious than the original Omicron variant. 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. There were very limited numbers of BA.2 in this study and no inferences can be made regarding BA.2. This will include analysing live samples of the new variant in our laboratories to investigate properties including its response to current vaccines. 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). 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 breakdown of cases by local authority is: The UK Health Security Agency (UKHSA) has identified 9 further cases of coronavirus (COVID-19) with mutations consistent with B.1.1.529 in England, in addition to the previous 13 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529. BA.2 has an increased growth rate compared to BA.1 in all regions of England where there are enough cases to assess it. "Looking at other countries where BA.2 is now overtaking, we're not seeing any higher bumps in hospitalisation than expected," the WHO's Dr Boris Pavlin says. Neither have currently been designated as variants of concern. It is not clear where BA.2 originated, but it was first detected in the Philippines in November. 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. But the preliminary assessment found no evidence that vaccines would be any less effective against symptomatic disease for either sub-variant. Analyses of sequenced SGTF samples has indicated that until mid-November, more than 99% of these were Delta cases. 2. In some countries, BA.2 accounts for more than half of sequenced Omicron cases, it adds. As is routine for any new variants under investigation, UKHSAis carrying out laboratory and epidemiological investigations to better understand the properties of this variant. To help us improve GOV.UK, wed like to know more about your visit today. 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. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. Our continued genomic surveillance allows us to detect them and assess whether they are significant. Two-thirds with Omicron say they had Covid before. However, it is not confirmatory as there are a number of other reasons that a sample might exhibit SGTF. 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. The individuals who have tested positive and their contacts have been asked to self-isolate. We have now identified cases in the East Midlands, East of England, London, South East and North West. 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. In the last week, VUI-21OCT-01 accounted for approximately 6% of all Delta cases. Runny nose/congestion. 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. Omicron BA.2 Variant Severity Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. Previous variants of concern which no longer meet the criteria will be redesignated. UKHSA continues to examine all available data relating to SARS-CoV-2 variants in the UK and abroad. Any variants showing evidence of spread are rapidly assessed. There have been recent reports of people who experience symptoms like those of viral meningitis, an inflammation of the brain and spinal cord membranes. A study of 8,500 households and 18,000 individuals conducted by Denmark's SSI found that BA.2 was "substantially" more transmissible than BA.1. This suggests that, as immunity begins to wane, these newly emerging BA.2 variants may fuel future waves of SARS-CoV-2 infection. As always, the booster vaccine remains the best protection against infection. A runny nose, gastrointestinal. 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. However, confidence levels for severity indicators for children are low because further analysis is required to compare the risk of hospitalisation between Omicron and Delta, and to assess the clinical nature of illness in children. Where individualsare suspected or confirmed to have theOmicron variantas the result of testing, their close contacts will be contacted by NHS Test and Trace, required to self-isolate and asked to take aPCRtest,regardless of whether they have been vaccinated. It is vital that everyone over the age of 40 who is eligible for a booster jab comes forward as soon as possible to get increased protection against this new variant. 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. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. 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. Scratchy throat. Currently, no experimental data has been reported about BA.2 and BA.3. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. So far, there have been 717 V-22OCT-01 sequences uploaded from the UK to the international GISAID database. The team at ZOE, a study that tracks symptoms . 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. 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. There will be a coprimary endpoint : Neutralizing antibody titers against the SARS-CoV-2 variant of most prominent public health interest according to pandemic evolution (among D614G, B.1.351, Omicron sub-variants BA.4-5, BQ1.1 and XBB or another recent variant) and against one of the variant targeted by the vaccines. 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. While prevalence remains high, make sure to wear your mask in indoor settings and take a lateral flow test before meeting others. 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. Getty Images BA.2 was. Please also make sure to follow all Government guidance to reduce the spread of infection. You have rejected additional cookies. At the moment there is much that is not yet clear. Dr Jenny Harries, Chief Executive of the UK Health Security Agency, said: Viruses mutate often and at random, and it is not unexpected that new variants will continue to arise as the pandemic goes on, particularly while the case rate remains high. Everyone over 18 is now able to walk into a vaccine centre, so do not hesitate to get yours. Omicron BA2 symptoms include taste loss. 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. Earlier COVID-19 variants affected the lung tissue more and had a higher likelihood of causing pneumonia and other severe outcomes.
