Our advanced sequencing capabilities enable us to find variants and take rapid action to limit onward spread. 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. A preliminary assessment by UKHSA did not find a difference in vaccine effectiveness, although it said there was no data yet available on severity. Face coverings in crowded indoor spaces and hand washing will help to reduce transmission of infection and are especially important if you have any respiratory symptoms. The v We now know that BA.2 has an increased growth rate which can be seen in all regions in England. Now more countries, particularly in Asia and Europe, are reporting an increase in cases driven by BA.2. One individual diagnosed in hospital has sadly died. In some places, growth in recorded cases of the sub-variant has been sharp. An ad blocker has likely prevented this video content from loading. As of 20 December,132individuals with confirmed Omicron have been admitted to or transferred from emergency departments. There were very limited numbers of BA.2 in this study and no inferences can be made regarding BA.2. moderate COVID-19 symptoms who are at high risk of . 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. 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. 2. What are the different symptoms doctors are seeing with omicron BA.2 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. Read about our approach to external linking. 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. There is still uncertainty around the significance of the changes to the viral genome, and further analyses will now be undertaken. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. 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. Telltale symptoms for Deltacron, Omicron, and the BA.2 Covid variants New sub-lineages within Delta continue to be identified. UKHSA is undertaking further detailed studies. 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. Until we have this evidence, we must exercise the highest level of caution in drawing conclusions about any significant risks to peoples health. 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. Omicron BA.2: 6 new symptoms indicate you are infected with - mint Omicron Sub-Variant BA.2: Symptoms, Differences, And Chances Of This analysis excludes individuals with confirmed previous COVID-19 infection. While BA.2 appears to be more transmissible than previous variants, there is no data yet to suggest that it is any more severe. 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. Read about our approach to external linking. 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. Neutralisation studies are currently being undertaken at the University of Oxford. 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. Top of the list with a prevalence of 80. 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. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. Studies have also shown that Omicron infects and multiplies in the upper airways 70 times faster than the previous Delta variant. What are the five main Omicron symptoms? - Open Access Government It appears to have a growth advantage compared to the version of Omicron, BA.1, that has swept the globe. Well be undertaking further analysis to investigate the small rise in the number of children admitted to hospital but currently coronavirus (COVID-19) poses a very low health risk to children and infants. Cases have been confirmed through whole genome sequencing in all 9 regions of England. SARS-CoV-2 Omicron variant - Wikipedia The UK Health Security Agency (UKHSA) has published its latest COVID-19 variant technical briefing. New 'stealth' Omicron subvariant presents two NEW symptoms, experts The Delta variant, for example, comprises 200 different sub-variants. We continue to monitor all recombinants closely, routinely through our world-leading genomic surveillance and sequencing capability. In some countries, BA.2 accounts for more than half of sequenced Omicron cases, it adds. Ba.2 Omicron Variant Symptoms - SymptomsTalk.net 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. That's because there could be cross-immunity - an infection with BA.1 could offer some protection against BA.2. One study has suggested that it may be difficult to identify this variant . Any variants showing evidence of spread are rapidly assessed. 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. 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. BA.2 Symptoms Usually Appear in This Order - Yahoo! Vaccine effectiveness (VE) against Omicron has again been updated in this weeks briefing. Genome sequencing among the states is not always fair. pic.twitter.com/ESQupxUet4. 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.. 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. Everyone over 18 is now able to walk into a vaccine centre, so do not hesitate to get yours. Fast-spreading new Covid stealth Omicron BA.2 variant and symptoms Scratchy throat. They also say that Omicron symptoms are typically mild, and herd immunity is at . As of 2 May 2022, 21 confirmed cases of Omicron BA.4 and 19 confirmed cases of Omicron BA.5 have been detected in England. All age groups are affected, including the 75s and over, who are due a spring booster jab to top up protection. Experts say BA.2 has extensive mutations and is about 40 percent more infectious than the original Omicron variant. Our data shows that LFD tests are similarly able to detect COVID-19 in individuals who have been exposed to Omicron as in those exposed to previous variants. 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). Covid BA.2 Omicron variant: The key symptoms to look out for What Is BA.2, the 'Stealth Omicron' Variant - Stealth Omicron Symptoms Work is underway to identify any links to travel to Southern Africa. 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. Effectiveness of first and second COVID19 mRNA vaccine monovalent And even if it does become the dominant version of Omicron, it may not actually alter the trajectory of the pandemic in countries that have seen a big wave of BA.1. The public health advice is the same for all current variants. What experts know about COVID-19 omicron subvariant BA.2 We have now identified cases in the East Midlands, East of England, London, South East and North West. Data for Scotland, Wales and Northern Ireland is not included in the UKHSA Technical Briefing. [92] Reactions [ edit] Vaccine producers [ edit] 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. So how worried should we be about this emerging variant? A second BTN162b2 booster was previously found to be 52% and 72% effective in preventing Omicron BA.1 infection and hospitalization, respectively, in adults 60 years. March 31, 2022. The UK Health Security Agency (UKHSA) has published variant technical briefing 37. 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. According to the ZOE study - conducted across Omicron and Delta waves for comparison - there are five key symptoms of the Omicron variant. BA.2: A more contagious version of the Omicron variant has been The most common omicron-related symptoms are: Cough. ; BA.5 sometimes gives rise to more marked symptomssometimes with digestive symptoms . However, it should serve as objective evidence that this pandemic is not over. Other countries that have uploaded more than 100 samples are India (530), Sweden (181), and Singapore (127). Wear a mask in crowded spaces and, when meeting people indoors, open windows and doors to ventilate the room. While BA.1 and BA.2 are similar, they are 20 mutations apart. Thats why its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. 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. The individuals who have tested positive and their contacts are all isolating. Two major BA.2 variant symptoms include dizziness and fatigue, as I wrote for the Deseret News. It will take only 2 minutes to fill in. What Are the Symptoms of the COVID BA. 2 Variant? Your Questions Delta remains the predominant variantin England, accounting for over 99% of all COVID-19 cases. 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 A major ailment is not to be expected for the age group 20-50 years. A further 16 cases have been identified in Scotland, bringing the total in Scotland to 29. There are also hybrid strains, such as XE, which is a combination of BA.1 and BA.2 By Alex Finnis 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. UKHSA has also published analyses related to the original Omicron strain BA.1. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. What Are the Symptoms of Omicron BA.5? - Verywell Health 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. . How are Covid rules changing across UK schools? The study also showed evidence to suggest that the BA.2 sub-variant is better able to evade vaccines. The earliest of these has a specimen date of 19 January 2022. Omicron BA.2: What we know about the Covid sub-variant 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. There are small numbers of cases in the UK and this designation is intended to allow investigation into the specific properties of this variant. The variant technical briefing also includes updated analysis on Omicron BA.2, currently the dominant variant in the UK. Our continued genomic surveillance allows us to detect them and assess whether they are significant. Data by variant related to intensive care unit admissions is presented and an analysis into the effect of the recent surge of Omicron cases in care homes is also available in the latest technical briefing. 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. 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. Data continues to show COVID-19 poses a very low health risk to children and infants. 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. It is not clear where BA.2 originated, but it was first detected in the Philippines in November. 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. However, a small change may be enough to cause a difference in the virus properties in some circumstances. Coronavirus: There's a third variant of Omicron 'BA.3'; all about the While growth rates can be overestimated in early analyses of a new variant, the apparent growth advantage is currently substantial. It is projected that if current trends continue unchanged, the UK will exceed one million infections a day by the end of this month. These early findings should be interpreted with caution as transmission data and dynamics can fluctuate, meaning that early findings can change quickly when new variants are identified. A booster dose was associated with a 74% reduced risk of hospitalisation in the first 2 to 4 weeks after vaccination, with the figure dropping to 66% 10 weeks or more after this dose. The Omicron variant sub-lineage known as BA.2 has been designated a variant under investigation ( VUI-22JAN-01) by the UK Health Security Agency (UKHSA). As part of UKHSAs routine genomic surveillance, approximately 15 to 20% of all positive PCR tests are also sent for sequencing. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. By the summer of 2022, the BA.5 variant was the most dominant strain in the US. 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. ; An increase in new cases is being . The UK Health Security Agency (UKHSA) has released variant technical briefing 41. 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. 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. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. The first genomes of this variant were uploaded to the international GISAID database on 22 November. Sliding to mild? Nopeomicron BA.2 caused worse COVID symptoms than BA The vaccination status was unknown for 6 people, while 8 had received a single dose. It is the best defence we have against this highly transmissible new variant. A NEW Covid-19 Omicron sub-variant is spreading across Ireland and is the most infectious strain yet. 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. 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. However, increases in SGTF can give a useful early indication of variant spread. 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. The data suggests this risk is significantly reduced following a booster vaccine, so I urge everyone to take up their booster when eligible. 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. Trends in SGTF over and time are however affected by the coverage of laboratories contributing to this surveillance data. However, cases of the variant continue to rise at an extraordinary rate already surpassing the record daily number in the pandemic. UK Health Security Agency (UKHSA) has published variant technical briefing 24. In a subgroup analysis of 4,800 people who were triple-vaccinated and infected with an omicron variant, the authors found that people with BA.2 were 64 percent more likely than BA.1-infected . 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. As prevalence increases, its more important than ever that we all remain alert, take precautions, and ensure that were up to date with COVID-19 vaccinations, which remain our best form of defence against the virus. BA.2 variant: Everything we know about the new Covid strain - Metro It contains updated analysis on Omicron hospitalisation risk, vaccine efficacy against symptomatic disease from Omicron, and the COVID-19 reinfection rate. This analysis is not an assessment of hospital severity, which will take further time to assess. 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. Delta and Omicron Cases are being eclipsed by BA2 Variant rapidly. What are the symptoms of BA.2? Our data shows that getting the booster vaccine is more effective against this variant than 2 doses alone. 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. However, with the spread of BA.4 and BA.5, that symptom seems to have returned, some doctors note. 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. 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. Our continued genomic surveillance allows us to further investigate variants that are growing within the UK. These are potentially biologically significant mutations which may change the behaviour of the virus with regards to vaccines, treatments and transmissibility. In the last week, VUI-21OCT-01 accounted for approximately 6% of all Delta cases. 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. Since BA.2 is a sub-strain of the Omicron variant, it is expected that its symptoms will be similar. 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). Work from home if you are able to, wear a mask indoors around other people, and ventilate indoor spaces well. We are continuing to monitor the data closely. It is also absolutely critical that we all do what we can to reduce transmission in the community so that we have time to administer as many booster doses as possible. This will include analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. 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. 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. This is to be expected and UKHSA is monitoring the situation closely. 2 or Stealth Omicron causes. BA.2, a SARS-CoV-2 Omicron Variant, Explained - Health Teams nationally and locally are working at pace to identify and trace all close contacts of every Omicron case. Omicron BA.2 Variant Severity 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. 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. 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. 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 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. It remains vital that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. The total number of confirmed cases in England is now 29. 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. Further information is also available in the latest variant technical briefing. 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. UKHSA continues to examine all available data relating to SARS-CoV-2 variants in the UK and abroad. One case is located in Camden, London, and one case is located in Wandsworth, London. 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. A separate UK study also found higher transmissibility for BA.2 compared to BA.1. This suggests that BA.5 is likely to become the dominant COVID-19 variant in the UK. UKHSA are continuing to monitor data on the BA.2 sub-lineage closely. Thanks to very high levels of vaccine coverage we already have a robust wall of defence against COVID-19 as new variants emerge. The percentage of people to have received a booster dose will also already be higher in older age groups and those with underlying health conditions due to prioritisation of the rollout so far. Protection against hospitalisation from vaccines is good against the Omicron variant. New Omicron Subvariant Is Spreading in India, U.S. Earlier COVID-19 variants affected the lung tissue more and had a higher likelihood of causing pneumonia and other severe outcomes. For some more vulnerable a third dose is available. 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. An important question is whether BA.2 or BA.3 will become a new dominating "variant of concern". The five most common symptoms of Omicron are: runny nose;. Scientists in the UK and abroad are closely monitoring BA.2, a sub-variant of Omicron. As viruses mutate into new variants, they sometimes split or branch off into sub-lineages. However, it remains too early to draw any definitive conclusions on hospital severity, and the increased transmissibility of Omicron and the rising cases in the over 60s population in England means it remains highly likely that there will be significant pressure on the NHS in coming weeks.
