UKHSA designated variant B.1.1.529 as a variant under investigation (VUI) on Thursday 25 November. The first sequences were submitted from the Philippines, and most samples have been uploaded from Denmark (6,411). The total number of confirmed cases in England is now 104. Of symptomatic cases, loss of smell and taste was found to be more common in people who tested positive for Delta than those who had Omicron. Dr Susan Hopkins, Chief Medical Advisor for UKHSA, said: Ongoing variant analysis is an important part of our pandemic response. 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. 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 first genomes of this variant were uploaded to the international GISAID database on 22 November. These are potentially biologically significant mutations which may change the behaviour of the virus with regards to vaccines, treatments and transmissibility. This analysis excludes individuals with confirmed previous COVID-19 infection. While growth rates can be overestimated in early analyses of a new variant, the apparent growth advantage is currently substantial. UKHSAwill continue to carry out laboratory and epidemiological investigations to better understand the characteristics of this variant. Thats why its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. 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 . BA.2 infections in Germany are also growing faster than BA.1 and Delta, according to Dr Meera Chand, Covid-19 director at the UKHSA. 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. 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. 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. Of those patients admitted to hospital,17had received a booster vaccine, 74 people had 2 doses and 27 people were not vaccinated. 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. 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 designation V-22JUL-01. 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. If you have symptoms take a PCR test and isolate at home until you receive a negative result. This matches a recent study led by Oxford University and the Office for National Statistics (ONS), using data from the COVID-19 Infection Survey produced by the latter. Everybody who is contacted or has symptoms should take aPCRtest as soon as possible, even if they have received a positive COVID-19PCRtest within the last 90 days. This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. 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. At this point it is not possible to determine where the sublineage may have originated. What is the stealth omicron, or BA.2, variant? We use some essential cookies to make this website work. Studiesof households and contactshave found that there is a higher risk of transmission to contacts from an Omicron case, when compared to Delta. Getting your booster jab remains the most effective way of protecting yourself and others from infection and severe disease. There is currently insufficient evidence to draw conclusions about growth advantage or other properties of this variant. Approximately half of PCR tests in the UK are able to detect SGTF. Experts in Kolkata say that BA.2 symptoms are mostly associated with abdomen and stomach instead of cough or shortness of breath. "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. UK Health Security Agency (UKHSA) has published variant technical briefing 24. 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. As with any other coronavirus (COVID-19) variant, the vast majority do not confer any advantage to the virus and die out relatively quickly. Updated analysisshows theadditional incremental benefit from each vaccine exposureincluding for boosters, even in those who have had prior infection. As viruses mutate into new variants, they sometimes split or branch off into sub-lineages. While on one hand, this statement gives a ray of hope that BA.2 sub variant of Omicron which was thought to be severe is mild as the BA.1 subvariant is, but on the other hand with the report of . UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. This will include analysing live samples of the new variant in our laboratories to investigate properties including its response to current vaccines. 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. Evidence continues to show that Omicron is transmitting more rapidly than the dominant Delta variant. Currently, no experimental data has been reported about BA.2 and BA.3. 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. Please make sure you follow all the available guidance. While prevalence remains high, make sure to wear your mask in indoor settings and take a lateral flow test before meeting others. 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. BA.2 continues to demonstrate a substantial growth advantage. This is to be expected and UKHSA is monitoring the situation closely. Dont include personal or financial information like your National Insurance number or credit card details. 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 highly transmissible Omicron variant now accounts for half of the world's infections. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. Fourteen people are reported to have died within 28 days of an Omicron diagnosis, ranging in age from 52 to 96 years old. You can change your cookie settings at any time. 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. 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. 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. Studies have already shown that this virus travels to different parts of the body, therefore gut-related issues are. Neither have been designated as variants of concern by UKHSA. BQ.1 (V-22OCT-01) is a BA.5 sub-lineage which has been designated on the basis of rapid growth. Nine cases have also been identified in Scotland, with 5 cases in the Lanarkshire area and 4 in the Greater Glasgow and Clyde area. In total, 40 countries have uploaded 8,040 BA.2 sequences to GISAID since 17 November 2021. However, vaccinated people are still less likely to get infected than unvaccinated individuals, and they are also less likely to pass it on. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. Work is underway to identify any links to travel. If you have any symptoms, take a test. 2023 BBC. 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. [92] Reactions [ edit] Vaccine producers [ edit] India is another country where BA.2 is rapidly replacing the Delta and Omicron BA.1 variant, according to molecular biologist Bijaya Dhakal. Genomes have now been uploaded from South Africa, Botswana and Hong Kong but the extent of spread is not yet determined. We will continue to monitor this situation closely and recommend appropriate public health measures if needed. We should all continue to test regularly with LFDs and take a PCR test if symptoms develop. 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. The World Health Organization has been monitoring SARS-CoV-2 (the virus that causes Covid-19) since January 2020, during which time the variant Omicron has been identified, which is technically known as BA.1 or B.1.1.529.The WHO is now monitoring a sub-variant of Omicron, known as BA.2, which has been described as "stealth Omicron," because it has genetic mutations that potentially make it . 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.. Vaccine effectiveness (VE) against Omicron has again been updated in this weeks briefing. The guidance on vaccination is changing to help all of us bolster our defences in the face of this new variant. 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. The UKHSAs COVID-19 variant technical briefing 43, published today, includes epidemiological analysis that shows that Omicron BA.4 and BA.5 now make up more than half of new COVID-19 cases in England, accounting for approximately 22% and 39% of cases, respectively. The two most reported symptom of patients infected by the Stealth Omicron variant is -dizziness and fatigue. Its not too late to catch up if youve missed boosters, or even first doses so please take your recommended vaccines. ; The incubation time (time to onset of symptoms) is a bit shorter: 3 days. 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. This analysis is not an assessment of hospital severity, which will take further time to assess. One dose of any vaccine was associated with a 35% reduced risk of hospitalisation among symptomatic cases with the Omicron variant, 2 doses with a 67% reduction up to 24 weeks after the seconddose and a 51% reduced risk 25 or more weeks after the seconddose. This is consistent with analysis published yesterday by Imperial College London and the University of Edinburgh. This assessment is based on analysis of UK data showing increased household transmission risk, increased secondary attack rates (such as the chance of each case infecting another individual) and increased growth rates compared to Delta.
