UKHSA is undertaking further detailed studies. As of May 2022, BA.2.12.1 was spreading in the US and two new subvariants of Omicron named BA.4 and BA.5, first detected in January 2022, spread in South Africa. Taste Lost is one of the Omicron BA2 Symptoms. Professor Susan Hopkins, Chief Medical Advisor at UKHSA said: It is clear that the increasing prevalence of Omicron BA.4 and BA.5 are significantly increasing the case numbers we have observed in recent weeks. 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. What are the symptoms of BA.2? BA.2 is found to be able to alarmingly reinfect patients originally infected by Omicron BA.1. None of these cases are known to have been hospitalised or died. The population rate of people becoming infected with Omicron after having previously contracted COVID-19 has increased sharply. We will continue to closely analyse all available biological, epidemiological and genomic evidence for any SARS-CoV-2 variant in the UK or internationally. Vaccination is critical to help us bolster our defences against this new variant so please get your first, second, third or booster jab as soon as you are eligible to protect yourself, your families and your communities. We will continue to monitor this situation closely and recommend appropriate public health measures if needed. 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. Dr Chand said: "So far, there is insufficient evidence to determine whether BA.2 causes more severe illness than Omicron BA.1. [92] Reactions [ edit] Vaccine producers [ edit] There are small numbers of cases in the UK and this designation is intended to allow investigation into the specific properties of this variant. UKHSA is monitoring the situation closely, in partnership with scientific and public health organisations across the world. "The symptoms of the Omicron variant, which includes the BA.2 lineage, and the Delta variant, are similar," says Dr. Erica Johnson, MD, the chair of the Infectious Disease Board of the . One of the most common symptoms of the Omicron subvariant BA.2 is nausea. Vaccination is critical to help us bolster our defences against this new variant please get your first, second, third or booster jab without delay. The BA.2 variant is a sibling of the BA.1, which swept across the country over Christmas. 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. The UK Health Security Agency (UKHSA) has released variant technical briefing 50. People suffering From the Omicron BA2 variant said they had fever and body Aches. Overall numbers of ICU admissions have decreased over time, but where data was available admissions with Omicron have increased from 9% to more than 50% in the most recent week. According to Denmark's Statens Serum Institut (SSI), BA.2 infections rose to account for about half of the country's reported Covid cases in January. 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. Consider wearing a face covering when in crowded places. A growth rate potentially compatible with the eventual replacement of the current dominant variant. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. 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. Stay at home if you have any respiratory symptoms or a fever and limit contact with others until you are feeling better, particularly if they are likely to be at greater risk if they contract COVID-19. But at that point the sub-variant still appeared to account for less than one in 20 cases. 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. AstraZeneca was the main vaccine used early in the programme in care homes and among those in clinical risk groups. The variant technical briefing also includes updated analysis on Omicron BA.2, currently the dominant variant in the UK. It includes a complete list of studies planned and already under way into the emerging variant. The genome of VUI-21OCT-01 does not have many mutations compared to Delta. There is now high confidence that the Omicron variant causes low severity of disease in adults. 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). UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. 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. Of those with Omicron, 9.5% have had COVID-19 before, which is likely to be a substantial underestimate of the proportion of reinfections, as many prior infections will have been asymptomatic and not picked up by the analysis. UKHSA is monitoring this closely. 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. However, it should serve as objective evidence that this pandemic is not over. UKHSA has also published analyses related to the original Omicron strain BA.1. The BA.2 subvariant of Omicron, or the "stealth" variant, has been outcompeting the previously dominant BA.1 subvariant in several countries. It contains epidemiological data and updated analysis of COVID-19 variants currently circulating in the UK. We continue to urge everyone who is eligible to get a COVID-19 vaccine and booster. Vaccination is critical to help us bolster our defences against becoming severely ill from this new variant please get your first, second, third or booster jab without delay. A runny nose, gastrointestinal. Hospital admissions are increasing, and we cannot risk the NHS being overwhelmed. Earlier COVID-19 variants affected the lung tissue more and had a higher likelihood of causing pneumonia and other severe outcomes. ; BA.5 sometimes gives rise to more marked symptomssometimes with digestive symptoms . 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. 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. 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. 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. 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. Read about our approach to external linking. So far there is not enough evidence to draw conclusions about transmissibility, severity or vaccine effectiveness. 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. While growth rates can be overestimated in early analyses of a new variant, the apparent growth advantage is currently substantial. 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. 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. A total 637 cases of XE a recombinant of Omicron BA.1 and BA.2 have been confirmed in the UK so far. 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. If you have any symptoms, take a test. Our continued genomic surveillance allows us to further investigate variants that are growing within 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. A major ailment is not to be expected for the age group 20-50 years. The Omicron BA.2 subvariant is fast becoming the dominant strain of COVID-19, with symptoms similar to previous strains of the virus. We have now identified cases in the East Midlands, East of England, London, South East and North West. Our advanced sequencing capabilities enable us to find variants and take rapid action to limit onward spread. The updated risk assessment includes indicators for infection severity in both adults and children. Omicron BA2 symptoms include taste loss. As of January 10 2022, 53 sequences of the BA.2 sub-lineage of Omicron had been identified in the United Kingdom. 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. This is consistent with analysis published yesterday by Imperial College London and the University of Edinburgh. But the preliminary assessment found no evidence that vaccines would be any less effective against symptomatic disease for either sub-variant. 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. The public health advice is the same for all current variants. 2 or Stealth Omicron causes. The most commonly-reported symptoms with the original Omicron variant were cough, fatigue, headache, congestion, and runny nose. The highly transmissible Omicron variant now accounts for half of the world's infections. Our continued genomic surveillance allows us to detect them and assess whether they are significant. 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. Work is underway to identify any links to travel. 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. 1 case has been identified in Wales. 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. This designation means that data relating to BA.2.75 will now be reported separately from other BA.2 cases. #India is another country where #SARS_CoV_2 BA.2 is rapidly replacing #Delta & #Omicron BA.1. Can Nigeria's election result be overturned? The UK has been hard-hit by a further spike in Covid-19 cases in recent weeks, with infections being driven by a sub-lineage of the Omicron variant known as BA.2 or "Stealth Omicron". The original Delta variant remains overwhelmingly dominant in the UK, making up approximately 99.8% of all cases. 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. 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. The Delta variant, for example, comprises 200 different sub-variants. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately.. 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. Dont worry we wont send you spam or share your email address with anyone. In the last week, VUI-21OCT-01 accounted for approximately 6% of all Delta cases. A NEW Covid-19 Omicron sub-variant is spreading across Ireland and is the most infectious strain yet. 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. 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. They save lives and prevent serious illness. 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. Headache. Those are pretty similar to what people experience with a cold or other seasonal viruses. This is very encouraging. 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. Updated Jan. 27, 2023 The omicron subvariant of COVID-19, BA.5, became one of the dominant strains of the virus in the fall of 2022 in the U.S. At that time, it was the most easily spread strain to date and is able to evade immunity from COVID infection and vaccination. A preliminary assessment by UKHSA did not find a difference in vaccine effectiveness, although it said there was no data yet available on severity. There were very limited numbers of BA.2 in this study and no inferences can be made regarding BA.2. The UK Health Security Agency (UKHSA) has announced the emerging SARS-CoV-2 variant known as B.1.1.529 as a variant under investigation (VUI). 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. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. UKHSA continues to examine all available data relating to SARS-CoV-2 variants in the UK and abroad. 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. 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. Early data shows that young children who are hospitalised experience mild illness and are discharged after short stays in hospital. 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 have now identified cases in the East Midlands, East of England, London, North East, North West, South East, South West and West Midlands. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. While BA.1 and BA.2 are similar, they are 20 mutations apart. 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 But the latest data suggests this extra protection starts to wane more rapidly, being about 15 to 25% lower from 10 weeks after the booster dose. 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. Dr Mary Ramsay, Head of Immunisation at UKHSA, said: These early estimates should be treated with caution but they indicate that a few months after the second jab, there is a greater risk of catching the Omicron variant compared to Delta strain. However, one must note, these are only early stage symptoms. Getty Images BA.2 was. The five key Omicron symptoms. This paper can be found as a pre-print, and the data is referred to in the latest vaccine surveillance report. "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. 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. The individuals who have tested positive and their contacts are all isolating. 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. UKHSA encourage everyone to continue to follow the most up-to date guidance. They say its possible that the virus has now changed its pattern and is affecting the stomach. They are our best defence and we have turbocharged our rollout programme inviting 7 million more people over the age of 40 to get their booster jab so even more people get protection from this disease.
