It is the best defence we have against this highly transmissible new variant. 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. Neither have been designated as variants of concern by UKHSA. This analysis found that the risk of presentation to emergency care or hospital admission with Omicron (testing for symptomatic or asymptomatic infection) was approximately half of that for Delta, while the risk of hospital admission alone with Omicron was approximately one-third of that for Delta. . "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 . 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. 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. The designation was made on the basis of increasing numbers of BA.2 sequences identified both domestically and internationally. 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). There is insufficient data to make any assessment of protection against severe disease, or to assess the severity of illness caused by Omicron. The most common omicron-related symptoms are: Cough. 2023 BBC. However, it should be noted both that this is early data and more research is required to confirm these findings. How are Covid rules changing across UK schools? The UK Health Security Agency (UKHSA) has published the latest variant technical briefing. Delta and Omicron Cases are being eclipsed by BA2 Variant rapidly. As of 17 May, 115 cases of BA.4 and 80 cases of BA.5 have been confirmed in England and the latest UKHSA variant technical briefing has been published today. 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. 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. 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. Now more countries, particularly in Asia and Europe, are reporting an increase in cases driven by BA.2. Once again, we urge everyone who is able to get a booster jab to come forward and do so. 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. UKHSA will continue to designate new variants, and these will receive a variant number (in the format V-date-number). BA.2 has an increased growth rate compared to BA.1 in all regions of England where there are enough cases to assess it. 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. Genomes have now been uploaded from South Africa, Botswana and Hong Kong but the extent of spread is not yet determined. Studies have also shown that Omicron infects and multiplies in the upper airways 70 times faster than the previous Delta variant. The BA.2 variant is a sibling of the BA.1, which swept across the country over Christmas. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. Two variants, CH.1.1 and XBB.1.5, appear to have a growth advantage in the UK. A number of Omicron variants are currently circulating in England, many of which have acquired mutations which may produce a degree of immune escape. The majority of these cases are located in London and the South East. The UK Health Security Agency (UKHSA) has identified 8 further cases of COVID-19 with mutations consistent with B.1.1.529 in England, in addition to the previous 5 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529. Initial data suggests that LFDs are as likely to detect Omicron as other variants including Delta, which has been the dominant variant in the UK from May to December 2021. However, the preliminary data showed effectiveness against the new variant appears to increase considerably in the early period after a booster dose, providing around 70% to 75% protection against symptomatic infection. In India, BA.2 is rapidly replacing the Delta and Omicron BA.1 variants of Covid, BA.2 was first detected in the Philippines, About half of new cases in Denmark are caused by BA.2, AOC under investigation for Met Gala dress, Mother who killed her five children euthanised, Alex Murdaugh jailed for life for double murder, The children left behind in Cuba's exodus, Zoom boss Greg Tomb fired without cause, US sues Exxon over nooses found at Louisiana plant. We constantly assess the genetic diversity within the known variants of concern (VOCs) to inform our ongoing public health response to the pandemic. The five key Omicron symptoms. [92] Reactions [ edit] Vaccine producers [ edit] 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. Well send you a link to a feedback form. Experts say BA.2 symptoms don't seem to be all that distinct from original Omicron (BA.1) or the immediately preceding Delta variant. 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. Fourteen people are reported to have died within 28 days of an Omicron diagnosis, ranging in age from 52 to 96 years old. ; BA.5 sometimes gives rise to more marked symptomssometimes with digestive symptoms . Since BA.2 is a sub-strain of the Omicron variant, it is expected that its symptoms will be similar. Studies have already shown that this virus travels to different parts of the body, therefore gut-related issues are. 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. While growth rates can be overestimated in early analyses of a new variant, the apparent growth advantage is currently substantial. Further information is also available in the latest variant technical briefing. Technical Briefing 34 contains further analysis on symptom comparison on Omicron and Delta. There is still uncertainty around the significance of the changes to the viral genome, and further analyses will now be undertaken. Both are variants in the Omicron family. AstraZeneca was the main vaccine used early in the programme in care homes and among those in clinical risk groups. As of January 10 2022, 53 sequences of the BA.2 sub-lineage of Omicron had been identified in the United Kingdom.

Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. In some places, growth in recorded cases of the sub-variant has been sharp. 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. A thirddose was associated with a 68% (95% confidence interval 52 to 82%) reduced risk of hospitalisation when compared to similar unvaccinated individuals. A further 16 cases have been identified in Scotland, bringing the total in Scotland to 29. 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. 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. 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. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. The individuals who have tested positive and their contacts are all isolating. UK Health Security Agency (UKHSA) has published variant technical briefing 24. 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. 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. 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. Consider wearing a face covering when in crowded places. BA.2 Omicron Subvariant Can Damage Your Lungs, Cause More Severe Disease Than You Can Expect: Study BA.2 Omicron Subvariant Can Damage Your Lungs, Cause More Severe Disease Than You Can. 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. Lower back pain. 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. And in England, more than 1,000 confirmed cases of BA.2 have been identified, according to the UK Health Security Agency (UKHSA). There is currently no evidence of community transmission within the UK. 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. Dr Chand said: "So far, there is insufficient evidence to determine whether BA.2 causes more severe illness than Omicron BA.1. Omicron continues to grow faster than Delta, with an increased risk of transmission, particularly in contacts outside of the household. Inthe SIREN study, a large cohort of healthcare workers are tested regularly by PCR to detect asymptomatic infection in addition to normal testing practices for symptomatic infection. There is currently no data on the severity of BA.2. Delta remains the predominant variantin England, accounting for over 99% of all COVID-19 cases. 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. As always, the booster vaccine remains the best protection against infection. We use some essential cookies to make this website work. 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.
