Follow the latest self-isolation rules if you develop symptoms wear a mask where required to do so, take regular LFD tests and observe good hand hygiene. It appears to have a growth advantage compared to the version of Omicron, BA.1, that has swept the globe. Overall, the original Omicron lineage, BA.1, is dominant in the UK and the proportion of BA.2 cases is currently low. We expect the vaccines to show higher protection against the serious complications of COVID-19, so if you havent yet had your first 2 doses please book an appointment straight away. 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. We have now identified cases in the East Midlands, East of England, London, South East and North West. 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. The individual is no longer in the UK, but UKHSA is carrying out targeted testing at locations where the positive case visited when they were likely to have been infectious. What Are the Symptoms of the COVID BA. 2 Variant? Your Questions 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. 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. 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. Any variants showing evidence of spread are rapidly assessed. However, it is not confirmatory as there are a number of other reasons that a sample might exhibit SGTF. BA.2 omicron symptoms According to the CDC, the symptoms of Covid-19, including BA.2, are: Fever or chills Cough Shortness of breath or difficulty breathing Fatigue Muscle or body. The full document and underlying data is available on GOV.UK. UKHSA are continuing to monitor data on the BA.2 sub-lineage closely. Thats why its so important that everybody, everywhere, takes simple steps to protect themselves from infection. Yet fears of another Omicron wave in the United States may be. These are potentially biologically significant mutations which may change the behaviour of the virus with regards to vaccines, treatments and transmissibility. 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. The total number of confirmed cases in England is now 104. According to the CDC, the Omicron variant spreads more easily than the original SARS-CoV-2 virus and the Delta variant. Work is underway to identify any links to travel. What Are the Symptoms of Omicron BA.5? - Verywell Health Vaccine effectiveness against severe disease from Omicron is not yet known but is expected to be significantly higher than protection against symptomatic disease. The individuals that have tested positive and their contacts are all isolating. 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. An estimated 78.7% of confirmed cases in England are BA.5 which was first identified in April and was designated as a Variant of Concern on 18 May. BA.3 shares most of its mutations with BA.1 and BA.2 except for one.

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. Vaccine efficacy analysis continues to show lower effectiveness for symptomatic Omicron disease. An important question is whether BA.2 or BA.3 will become a new dominating "variant of concern". 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. 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. 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. Getty Images BA.2 was. It is projected that if current trends continue unchanged, the UK will exceed one million infections a day by the end of this month. 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. Download the data.xlsx. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. 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. 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.

The UK Health Security Agency (UKHSA) has released variant technical briefing 41. You have accepted additional cookies. This sub-lineage, which was designated by Pangolin on 6 December 2021, does not have the spike gene deletion at 69-70 that causes S-gene target failure (SGTF), which has previously been used as a proxy to detect cases of Omicron. Case rates remain high throughout the UK and we must remain vigilant and take up vaccinations. Among those who had received 2 doses of Pfizer or Moderna, effectiveness dropped from around 65 to 70% down to around 10% by 20 weeks after the seconddose. There is no data to suggest that BA.2 leads to more severe disease than previous Omicron sub-variants. 34 Subsequent studies that were performed in periods when a mix of BA.1, BA.2, BA.4, and BA.5 viruses circulated have reported low effectiveness of a second booster against . BA.2 continues to demonstrate a substantial growth advantage. Analysis by the UKHSA suggests it could be substantial, although there is a risk of over-estimating growth advantage in the early stages. 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. Its 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. Genomes have now been uploaded from South Africa, Botswana and Hong Kong but the extent of spread is not yet determined. Since the middle of February, this growth rate has settled at approximately 75% higher than other circulating Omicron lineages in England. 2 or Stealth Omicron causes. UK Health Security Agency (UKHSA) has published variant technical briefing 24. The total number of confirmed cases in England is now 22. The Philippines' Department of Health (DOH) said the BA.2 sub-lineage was already prevalent in samples it received at the end of January. 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. 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. No cases have been identified in the UK. BA.2 is found to be able to alarmingly reinfect patients originally infected by Omicron BA.1. In the UK, 38 cases of XF have been identified, though none have been seen since mid February. This will include analysing live samples of the new variant in our laboratories to investigate properties including its response to current vaccines. Lower back pain. The COVID Omicron sub-variant BA.2, informally dubbed the "Stealth Omicron" variant, is able to reinfect people who have already had Omicron, a new study suggests. 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. This analysis excludes individuals with confirmed previous COVID-19 infection. An ad blocker has likely prevented this video content from loading.
