Please take up this offer as soon as you are invited to protect yourself, your families and your communities. This analysis found that the risk of presentation to emergency care or hospital admission with Omicron (testing for symptomatic or asymptomatic infection) was approximately half of that for Delta, while the risk of hospital admission alone with Omicron was approximately one-third of that for Delta. BA.2 version of omicron is rising in the U.S., but experts remain According to the COVID Symptom Study, the five most common symptoms are the same: Runny nose, headache, fatigue, sneezing and sore throat. BA.2 is believed to be far more contagious than the earlier Omicron strain, and was blamed for a fresh surge in Denmark. Whilst Omicron BA.4 and BA.5 are in the early stages of growth in the UK, analysis of the available data suggests that they are likely to have a growth advantage over the currently-dominant Omicron BA.2 variant. In the last week, VUI-21OCT-01 accounted for approximately 6% of all Delta cases. The Omicron Variant of COVID-19 - WebMD Our advanced sequencing capabilities enable us to find variants and take rapid action to limit onward spread. While signs remain encouraging on Omicrons severity compared with Delta, the high levels of community transmission continue and may cause pressures on health services.

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. Studies have also shown that Omicron infects and multiplies in the upper airways 70 times faster than the previous Delta variant. Any variants showing evidence of spread are rapidly assessed. Omicron BA.5 variant | COVID-19 | UC Davis Health The BA.2 variant is a sibling of the BA.1, which swept across the country over Christmas. Vaccination is critical to help us bolster our defences against this new variant please get your first, second or booster jab without delay. You have rejected additional cookies. Infection rate corrected to one million infections a day. Its not too late to catch up if youve missed boosters, or even first doses so please take your recommended vaccines. Those mutations are shared with the original omicron, but BA.2 also has . The individuals that have tested positive are not connected to each other and are not linked to the previously confirmed cases. Booster doses also increase the protection against symptomatic and asymptomatic infection which will reduce transmission in the population. Booster jabs are protecting people against infection and severe disease so I urge you to play your part in our national mission and get boosted now. 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 . Other countries that have uploaded more than 100 samples are India (530), Sweden (181), and Singapore (127).

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. These early findings should be interpreted with caution as transmission data and dynamics can fluctuate, meaning that early findings can change quickly when new variants are identified. Consider wearing a face covering when in crowded places. Until the week beginning 23 November 2021, the weekly count of cases with SGTF was routinely less than 150, making up less than 0.1% of all cases. 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. 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. The technical briefing also includes early analysis of vaccine effectiveness against the Omicron variant compared to Delta. In the most recent week of data (specimen dates from 30 November 2021 reported as of 6 December), the number of cases with SGTF has increased to 705.

This will include analysing live samples of the new variant in our laboratories to investigate properties including its response to current vaccines. 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. The UK Health Security Agency (UKHSA) has released variant technical briefing 41. A further 16 cases have been identified in Scotland, bringing the total in Scotland to 29. 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. 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. The areas with the largest number of confirmed cases are London (146) and the South East (97). Data continues to show COVID-19 poses a very low health risk to children and infants.

We will continue to monitor this situation closely and recommend appropriate public health measures if needed. While BA.1 and BA.2 are similar, they are 20 mutations apart. A number of Omicron variants are currently circulating in England, many of which have acquired mutations which may produce a degree of immune escape. Runny or congested nose Feeling fatigued Headache New, continuous cough Shortness of breath or difficulty breathing Muscle or body aches New loss of a sense of taste or smell Sore throat Nausea or vomiting Diarrhoea They advise that if you develop one or more of these symptoms you should take a Covid test as soon as possible.
