Data continues to show COVID-19 poses a very low health risk to children and infants. Cases have been confirmed through whole genome sequencing in all 9 regions of England. UKHSA encourage everyone to continue to follow the most up-to date guidance. BA.2.75.2 as a new variant but singled it out as an . This is not an unusual occurrence and several recombinant SARS-CoV-2 variants have been identified over the course of the pandemic. 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. 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. Fatigue. BQ.1 (V-22OCT-01) is a BA.5 sub-lineage which has been designated on the basis of rapid growth. Two variants, CH.1.1 and XBB.1.5, appear to have a growth advantage in the UK. 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. In some places, growth in recorded cases of the sub-variant has been sharp. Omicron has a deletion atposition69/70of the spike proteinwhich allows it to be tracked through S gene target failure(SGTF)in some PCR tests. BA.2 attacking abdomen instead of lungs. There were very limited numbers of BA.2 in this study and no inferences can be made regarding BA.2. However, with the spread of BA.4 and BA.5, that symptom seems to have returned, some doctors note. An important question is whether BA.2 or BA.3 will become a new dominating "variant of concern". moderate COVID-19 symptoms who are at high risk of . Work from home if you are able to, wear a mask indoors around other people, and ventilate indoor spaces well. This analysis shows you are up to 8 times more likely to end up in hospital as a result of COVID-19 if you are unvaccinated. Ongoing analysis by UKHSA has found no evidence that infection with Omicron BA.2 results in a greater risk of hospitalisation, compared to Omicron BA.1. The BA.2 subvariant has been referred to as stealth Omicron because it contains genetic mutations that can make it harder to distinguish from the . UKHSAwill continue to carry out laboratory and epidemiological investigations to better understand the characteristics of this variant. Any variants showing evidence of spread are rapidly assessed. The individuals that have tested positive are not connected to each other and are not linked to the previously confirmed cases. "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. Top of the list with a prevalence of 80. Effectiveness of first and second COVID19 mRNA vaccine monovalent Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately.. BA.2 is found to be able to alarmingly reinfect patients originally infected by Omicron BA.1. 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. ; An increase in new cases is being . 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. 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. There are small numbers of cases in the UK and this designation is intended to allow investigation into the specific properties of this variant. New Omicron BA.2 variant symptoms - What we know so far - Yahoo Life UK Everybody who is contacted or has symptoms should take a PCR test as soon as possible, even if they have received a positive COVID-19 PCR test within the last 90 days. At this point it is not possible to determine where the sublineage may have originated. 2. 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. 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. Working from home where possible, consistently wearing masks in crowded or enclosed spaces, washing your hands regularly and isolating and getting tested if you feel unwell are also vitally important in reducing the impact of COVID-19 this winter. 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. While there is a suggestion that this wanes slightly after 15 weeks, protection in this age group remains high at over 85%. According to Baric, Omicron is the first SARS-CoV-2 variant to evolve in the context of mounting immunity in the populationthe result of vaccines and prior infection with other forms of the . In severe cases, the SpO2 Level may also decrease. What Are the Symptoms of Omicron BA.5? - Verywell Health Booster doses also increase the protection against symptomatic and asymptomatic infection which will reduce transmission in the population. As is routine for any new variants under investigation,UKHSAis carrying out laboratory and epidemiological investigations to better understand the characteristics of this variant. With the original version of the omicron variant, which swept across the U.S. at a dizzying speed last winter, the loss of taste and smell was not as common as with the earlier alpha and delta variants. BA.2 is estimated to account for approximately 93.7% of cases in England, with the highest prevalence in the South East (96.4%) and the lowest in the East Midlands (91.1%). Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. 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. 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. 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). Case rates remain high throughout the UK and we must remain vigilant and take up vaccinations. This new mutation dubbed BA.2.75 is concerning scientists because it appears to spread fast, bypassing the protection offered by COVID-19 vaccines and immunity from previous infection, the Associated Press reported Monday. These changes will take effect as of 1 April 2022 and will be reflected in full in future technical briefings. Its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately. Analysis shows that protection against symptomatic disease 2 to 4 weeks after a booster dose ranges from around 65% to 75%, dropping to 55% to 65% at 5 to 9 weeks and 45% to 50% 10 weeks or more following the booster dose. All 3 subvariants have spike protein mutations of L452 and elude immunity from prior BA1 infection. Immunogenicity and Reactogenicity of the Beta-variant Recombinant The UK Health Security Agency (UKHSA) has released variant technical briefing 41. Please take up this offer as soon as you are eligible to protect yourself, your families and your communities. A number of Omicron variants are currently circulating in England, many of which have acquired mutations which may produce a degree of immune escape. COVID-19 variants identified in the UK - latest updates - GOV.UK COVID-19 has not gone away, so it is also vitally important that people continue to follow the guidance. Data and analysis will be released in due course through our regular surveillance reporting. Teams nationally and locally are working at pace to identify and trace all close contacts of every Omicron case. And now, dizziness and fatigue are beginning to emerge as potential symptoms of the new sub-strain of Omicron, along with the original Covid symptoms. Of these, XD and XF are recombinants of Delta and Omicron BA.1, while XE is a recombinant of Omicron BA.1 and BA.2. The variant technical briefing also includes updated analysis on Omicron BA.2, currently the dominant variant in the UK. Experts in Kolkata say that BA.2 symptoms are mostly associated with abdomen and stomach instead of cough or shortness of breath. 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. Dizziness, Fatigue: Common symptoms of Stealth Omicron you - mint 1 case has been identified in Wales. There are also hybrid strains, such as XE, which is a combination of BA.1 and BA.2 By Alex Finnis They also say that Omicron symptoms are typically mild, and herd immunity is at . COVID & Gut Health: Why Are Omicron, BA.2 Causing More - TheQuint The Delta variant sub-lineage known as Delta AY.4.2 was designated a variant under investigation (VUI) by the UK Health Security Agency (UKHSA) on 20 October 2021 and has been given the official name VUI-21OCT-01. Therefore, although early suggestions are that individuals may be less likely to require hospitalisation, many more people are likely to become infected. Work is underway to identify any links to travel to Southern Africa. As always, the booster vaccine remains the best protection against infection. This is consistent with analysis published yesterday by Imperial College London and the University of Edinburgh. Omicron continues to grow faster than Delta, with an increased risk of transmission, particularly in contacts outside of the household. It is not clear where BA.2 originated, but it was first detected in the Philippines in November. Wear a mask in crowded places, including public transport and shops, to ensure we all help break the chains of transmission and slow the spread of this new variant. 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. However, it should be noted both that this is early data and more research is required to confirm these findings. BA.2 version of omicron is rising in the U.S., but experts remain
