XBB (V-22OCT-02) is a recombinant lineage derived from 2 previous Omicron sublineages. How are Covid rules changing across UK schools? Studies have already shown that this virus travels to different parts of the body, therefore gut-related issues are. Studiesof households and contactshave found that there is a higher risk of transmission to contacts from an Omicron case, when compared to Delta. 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. What's the least amount of exercise we can get away with? Genome sequencing among the states is not always fair. pic.twitter.com/ESQupxUet4. Omicron symptoms: What we know about illness caused by the new subvariants "The symptoms of the Omicron variant, which includes the BA.2 lineage, and the Delta variant, are similar," says Dr. Erica Johnson, MD, the chair of the Infectious Disease Board of the . Any variants showing evidence of spread are rapidly assessed.

Dr Meera Chand, Director of Clinical and Emerging Infections at UKHSA, said: The reclassification of these variants as variants of concern reflects emerging evidence on the growth of BA.4 and BA.5 internationally and in the UK. What is Omicron sub-variant BA.2? All we know about the symptoms and In this analysis, the risk of hospitalisation is lower for Omicron cases with symptomatic or asymptomatic infection after 2 and 3 doses of vaccine, with an 81% (95% confidence interval 77 to 85%) reduction in the risk of hospitalisation after 3 doses compared to unvaccinated Omicron cases. 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. Everyone should complete a primary course as soon as possible for most this will be a first and second dose.

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 focussed contact tracing. According to Denmark's Statens Serum Institut (SSI), BA.2 infections rose to account for about half of the country's reported Covid cases in January. Previous updates were published by Public Health England. What are the most common symptoms of Omicron BA.2? 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. That's because there could be cross-immunity - an infection with BA.1 could offer some protection against BA.2. Everyone over 18 is now able to walk into a vaccine centre, so do not hesitate to get yours. Omicron soon began branching off into a number of subvariants: BA.2 took off in the spring, and BA.5 came to dominate towards the end of the summer. The individuals who have tested positive and their contacts have been asked to self-isolate. A separate UK study also found higher transmissibility for BA.2 compared to BA.1. 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. 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. UKHSAs most recent variant technical briefing can be found on GOV.UK. 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. There are simple things you can do in your daily life that will help reduce the spread of COVID-19 and other respiratory infections and protect those at highest risk. In addition, UKHSA has published data which shows the detection of cases exhibiting S-gene target failure (SGTF) in recent weeks across the country. Sajid Javid, Secretary of State for Health and Social Care, said: Todays new data shows how important booster jabs are to protect us against this variant. They save lives and prevent serious illness. UKHSA continues to examine all available data relating to SARS-CoV-2 variants in the UK and abroad. The genome of VUI-21OCT-01 does not have many mutations compared to Delta. Top of the list with a prevalence of 80. The BA.2 subvariant of Omicron, or the "stealth" variant, has been outcompeting the previously dominant BA.1 subvariant in several countries.

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. The proportion of test results displaying SGTF has been very low in recent months but an increase has been observed in the past week. However, one must note, these are only early stage symptoms. 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. 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. To date, there have been 426 cases of Omicron BA.2 confirmed by Whole Genome Sequencing (WGS), with the earliest dated 6 December 2021. 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. But at that point the sub-variant still appeared to account for less than one in 20 cases. Thats why its critical that anyone with COVID-19 symptoms isolates and gets a PCR test immediately..
