Studies of contacts show that Omicron is transmitting more effectively than Delta. 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. There is evidence that protection against symptomatic disease wanes after the second dose of vaccine, and then improves after the booster. These include a high temperature, a new. The v 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. Please also make sure to follow all Government guidance to reduce the spread of infection. What's the least amount of exercise we can get away with? 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. What are the symptoms of BA.2? Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. 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. 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. An ad blocker has likely prevented this video content from loading. The two most reported symptom of patients infected by the Stealth Omicron variant is -dizziness and fatigue. UKHSAwill continue to carry out laboratory and epidemiological investigations to better understand the characteristics of this variant. We are continuing to monitor the data closely. 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. XD has not been identified in the UK to date, though 49 cases have been reported to global databases, the majority of these are in France. Where variant information was available, the majority of intensive care unit (ICU) admissions from 24 November 2021 to 19 January 2022 had Delta infections. Things you can choose to do are: The UK Health Security Agency (UKHSA) has elevated the classification of the COVID-19 variants Omicron BA.4 and Omicron BA.5 to variants of concern (VOCs) on the basis of observed growth. Teams nationally and locally are working at pace to identify and trace all close contacts of every Omicron case. Currently, the Omicron variant has BA.1, BA.2, BA.3, and B.1.1.529 sub-variants, of which the BA.1 was dominant a few months before, and scientists have recently warned about the BA.2 sub-variant . They could be strangers (for example people you sit next to on public transport) or people you may have regular contact with (for example friends and work colleagues). Approximately half of PCR tests in the UK are able to detect SGTF. An individual with Omicron is estimated to be between 31 and 45% less likely to attend A&E compared to Delta, and 50 to 70% less likely to be admitted to hospital. So how worried should we be about this emerging variant? March 31, 2022. The data suggests this risk is significantly reduced following a booster vaccine, so I urge everyone to take up their booster when eligible. The UK Health Security Agency (UKHSA) has identified 2 further cases of COVID-19 with mutations consistent with B.1.1.529 in England, in addition to the previous 3 confirmed cases of the SARS-CoV-2 variant known as B.1.1.529 on 27 and 28 November. Other countries that have uploaded more than 100 samples are India (530), Sweden (181), and Singapore (127). Recent studies suggest that BA.2 has a. 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). BA.2 continues to demonstrate a substantial growth advantage. As of 24 January 2022, 1,072 genomically confirmed cases of BA.2 have been identified in England and all assessments remain preliminary whilst case numbers are relatively low. Studies in the UK reveal (where stealth Omicron is already spreading at a high rate) that people infected with the sub-variant show gut-related . In severe cases, the SpO2 Level may also decrease. UKHSA has performed an initial laboratory evaluation of the current lateral flow devices (LFDs) for COVID-19 in current use in the UK. Currently, approximately half of all tests conducted in the UK are able to detect SGTF. 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. Thats why its so important that everybody, everywhere, takes simple steps to protect themselves from infection. 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. B.1.1.529 has a large number of mutations in the gene coding for the spike protein, and also in other parts of the viral genome. In the UK, 38 cases of XF have been identified, though none have been seen since mid February. This particular recombinant, XE, has shown a variable growth rate and we cannot yet confirm whether it has a true growth advantage. According to the World Health Organization (WHO), nearly 99% of viral DNA submitted to the global GISAID database as of 25 January were identified as this sub-variant. Work is underway to identify any links to travel to Southern Africa. Vaccination remains our best defence against future COVID-19 waves, so it is still as important as ever that people come take up all the doses for which they are eligible as soon as possible. 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. Both have links to travel to Southern Africa. Work from home if you are able to, wear a mask indoors around other people, and ventilate indoor spaces well. We are particularly grateful to health protection specialists and the government of South Africa for early sharing of local information on the omicron variant in an exemplary way to support global health security. 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. The individuals that have tested positive and their contacts are all isolating. 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. This analysis is preliminary and highly uncertain because of the small numbers of Omicron cases currently in hospital, inability to effectively measure all previous infections and the limited spread of Omicron into older age groups. While signs remain encouraging on Omicrons severity compared with Delta, the high levels of community transmission continue and may cause pressures on health services. UKHSAs most recent variant technical briefing can be found on GOV.UK. Protection against hospitalisation from vaccines is good against the Omicron variant. The full document and underlying data is available on GOV.UK. A detrimental change in biological properties (changes in transmissibility, severity or immune evasion) compared to the current dominant variant. This is more promising data which reinforces just how important vaccines are. The team at ZOE, a study that tracks symptoms . Whilst there are insufficient data to quantify either vaccine effectiveness or risk of reinfection in the UK exactly, the observed growth, case distribution and early analyses in both South Africa and the UK are consistent with some loss of immune protection against infection. 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. Over 40% of hospital admissions were in London. 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. UKHSA will continue to designate new variants, and these will receive a variant number (in the format V-date-number). Neither BQ.1 nor XBB have been designated as variants of concern and UKHSA is monitoring the situation closely, as always. At the moment there is much that is not yet clear. The UK Health Security Agency (UKHSA) has published variant technical briefing 37. As we all work to limit the high levels of transmission of this variant over the Christmas period, we are urging people to test regularly, particularly before attending social gatherings. Studies have also shown that Omicron infects and multiplies in the upper airways 70 times faster than the previous Delta variant. 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. That contrasts to Denmark, where it has become dominant. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. 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. 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. As I previously reported, omicron subvariants have a shorter incubation period, which is why the symptoms may appear earlier. The worst symptom is a "throat on fire," said University of California, San Francisco's Dr. Peter Chin-Hong. moderate COVID-19 symptoms who are at high risk of . As of 30 November 2021, there are 22 confirmed cases of Omicron (B.1.1.529), identified through sequencing or genotyping in England. Since then, the Centers for Disease Control and Prevention (CDC) has classified two subvariants, BA.1.1 and BA.2. "It's important to know and recognize all of the. Of these, 20 were in England, 3 in Scotland and 1 in Wales. Our data also show that 17.5 per cent of people aged 75 years and over have not had a vaccine within the past six months, putting them more at risk of severe disease. What we know is that it is certainly growing as a proportion of overall cases in 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. 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. ; BA.5 sometimes gives rise to more marked symptomssometimes with digestive symptoms . 8 Research published in April 2022 in The Lancet also found. We have now identified cases in the East Midlands, East of England, London, South East and North West. 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. The most affected local authorities are West Northamptonshire, where there are 49 confirmed cases and 68 SGTF, and Manchester, where there are 7 confirmed cases and 61 SGTF. 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. [92] Reactions [ edit] Vaccine producers [ edit] No cases have been identified in the UK. Well be undertaking further analysis to investigate the small rise in the number of children admitted to hospital but currently coronavirus (COVID-19) poses a very low health risk to children and infants. Its critical that anyone with COVID-19 symptoms isolates and gets aPCRtest immediately. Increased case detection through focused contact tracing has led to more cases of the Omicron variant being identified and confirmed, as we have seen in other countries globally. 1 case has been identified in Wales. There is further data showing that effectiveness against symptomatic disease is significantly lower compared to the Delta variant, and wanes more quickly. Therefore, although early suggestions are that individuals may be less likely to require hospitalisation, many more people are likely to become infected. Scratchy throat. There will be no other categorisation of variants, including no variant under investigation (VUI) category. 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. COVID-19 has not gone away, so it is also vitally important that people continue to follow the guidance. 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. There is still uncertainty around the significance of the changes to the viral genome, and further analyses will now be undertaken. For the first time, this data includes analysis on vaccine effectiveness 15+ weeks after the booster dose. There can be several reasons for growth advantage, but in the case of BA.4 and BA.5, laboratory data suggests a degree of immune escape which is likely to contribute.
