UKHSA is constantly monitoring the situation and working to understand the implications for public health. 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. Effectiveness of first and second COVID19 mRNA vaccine monovalent The highly transmissible Omicron variant now accounts for half of the world's infections. 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. According to the ZOE study - conducted across Omicron and Delta waves for comparison - there are five key symptoms of the Omicron variant. 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). Fast-spreading new Covid stealth Omicron BA.2 variant and symptoms Data continues to show COVID-19 poses a very low health risk to children and infants. The five most common symptoms of Omicron are: runny nose;. Typical meningitis symptoms include neck stiffness or pain, numbness, tingling, and sensitivity to light. Neither have been designated as variants of concern by UKHSA. Added breakdown of cases by local authority to latest update. 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. In addition, UKHSA has published data which shows the detection of cases exhibiting S-gene target failure (SGTF) in recent weeks across the country. Dr Meera Chand, Director of Clinical and Emerging Infections, UKHSA, said: Through our genomic surveillance we continue to see evolution of variants in the Omicron family. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. 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. You have rejected additional cookies. UKHSA is updating its variant classification system to give a clearer indication of which variants have significant changes compared to the current dominant variant. The latest Omicron SARS-CoV-2 subvariant, which scientists have labeled BA.2.12.1, is on track to become the most virulent strain in the United States currently. 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. Technical Briefing 34 contains further analysis on symptom comparison on Omicron and Delta. It is therefore absolutely critical that we all do everything that we can to help break the chains of transmission and slow the spread of this new variant. Since the middle of February, this growth rate has settled at approximately 75% higher than other circulating Omicron lineages in England. 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. Thats why its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. 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. 8 Research published in April 2022 in The Lancet also found. It is not clear where BA.2 originated, but it was first detected in the Philippines in November. The proportion of test results displaying SGTF has been very low in recent months but an increase has been observed in the past week. 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. Stealth BA.2 Omicron Variant Can Reinfect People Who Had BA - Newsweek Analysis by the UKHSA suggests it could be substantial, although there is a risk of over-estimating growth advantage in the early stages. The UK Health Security Agency (UKHSA) has published the latest variant technical briefing. It is still too early to determine next steps, so please stay cautious this Christmas and get your booster as soon as possible to protect yourself and your loved ones.

I urge you to come forward as soon as youre eligible to help keep yourself and your loved ones safe. The omicron variant of the coronavirus was first detected in late 2021. 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. The UK Health Security Agency (UKHSA) has released a new variant technical briefing detailing updated analysis of epidemiological and genomic data relating to SARS-CoV-2 variants currently circulating in the UK, including the XBB.1.5 variant which has been increasing in the US in recent months. The total number of confirmed cases in England is now 22. It is critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. However, some experts believe that BA.2 doesn't present symptoms different from the original Omicron. UKHSA will continue to designate new variants, and these will receive a variant number (in the format V-date-number). These are potentially biologically significant mutations which may change the behaviour of the virus with regards to vaccines, treatments and transmissibility. Please make sure you follow all the available guidance. 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. No cases have been identified in the UK. We have now identified cases in the East Midlands, East of England, London and North West. 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. 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. There is insufficient data to make any assessment of protection against severe disease, or to assess the severity of illness caused by Omicron. This is very encouraging. Runny nose/congestion. As with previous variants, experts believe vaccines will continue to be highly effective against severe illness, hospitalisation, and death. One of the most common symptoms of the Omicron subvariant BA.2 is nausea. As viruses mutate often and at random, it is not unusual for small numbers of cases to arise featuring new sets of mutations. The individuals that have tested positive and their contacts are all isolating. There is currently no evidence of community transmission within the UK. Vaccine efficacy analysis continues to show lower effectiveness for symptomatic Omicron disease. So how worried should we be about this emerging variant? In its early days, the variant caused an alarming spike in COVID-19 cases in South Africathey went from 300 a day in mid-November 2021 to 3,000 a day at the end of that month. Surefire Signs Omicron is in Your Body Eat This Not That Since then, several sub-variants of Omicron surfaced, including BA.2, BA.3, BA.4, and BA.5. The first sequences were submitted from the Philippines, and most samples have been uploaded from Denmark (6,411). Getting your booster jab remains the most effective way of protecting yourself and others from infection and severe disease. The rapid spread of Omicron BA.2: What studies say - Medical News Today Approximately half of PCR tests in the UK are able to detect SGTF. Studiesof households and contactshave found that there is a higher risk of transmission to contacts from an Omicron case, when compared to Delta. The earliest of these has a specimen date of 19 January 2022. The Omicron BA.2 subvariant is fast becoming the dominant strain of COVID-19, with symptoms similar to previous strains of the virus. Omicron BA.2 Variant: 5 New Symptoms That Indicates You Are Infected BA.1 accounts for most of the cases. The new strain has several key mutations, with the most important of those occurring in the spike protein that studs the outside of the virus. This includes analysing live samples of the new variant in our laboratories to investigate properties such as response to current vaccines. In severe cases, the SpO2 Level may also decrease. All age groups are affected, including the 75s and over, who are due a spring booster jab to top up protection. Overall, data shows significant reductions in neutralisation against several of the newly emergent variants (BA.2.75.2, BA.2.3.20 and BJ.1), compared to BA.2, BA.4 and the dominant BA.5. However, a small change may be enough to cause a difference in the virus properties in some circumstances. Overall, the original Omicron lineage, BA.1, is dominant in the UK and the proportion of BA.2 cases is currently low. 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. Work is underway to identify any links to travel to Southern Africa. Cases are currently very high in the UK, and even a relatively low proportion requiring hospitalisation could result in a significant number of people becoming seriously ill. ; BA.5 sometimes gives rise to more marked symptomssometimes with digestive symptoms . UKHSA will continue to monitor the situation closely as a matter of routine, as we do all data relating to SARS-CoV-2 variants both in the UK and internationally. This designation means that data relating to BA.2.75 will now be reported separately from other BA.2 cases. While prevalence remains high, make sure to wear your mask in indoor settings and take a lateral flow test before meeting others. UKHSA is carrying out targeted testing at locations where the positive cases were likely to be infectious. 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. The risk assessment also suggests that Omicron displays a reduction in protection offered by having had a previous infection or vaccination. Wed like to set additional cookies to understand how you use GOV.UK, remember your settings and improve government services. Omicron has a deletion atposition69/70of the spike proteinwhich allows it to be tracked through S gene target failure(SGTF)in some PCR tests.

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). Further information is also available in the latest variant technical briefing. 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 . This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. We continue to monitor all recombinants closely, routinely through our world-leading genomic surveillance and sequencing capability. New sub-lineages within Delta continue to be identified.
