Yesterday the UK passed a grim milestone – 78,000 confirmed cases of coronavirus in a single day. It is a new record and one that is set to be smashed in the coming days and weeks as the Omicron variant rips through communities. London has seen the sharpest rise in Omicron cases thus far and this concentration has proven useful for researchers seeking to understand the impact of the variant.
Initial data analysed by the ZOE COVID Study, which tracks the movements of the virus via user submissions to its app, suggests there is a symptomatic profile to the new variant.
In order to take a first look at the potential symptom profile of Omicron, this week ZOE conducted an initial analysis of symptom data from positive cases in London.
London was selected due to the higher prevalence of Omicron compared to other regions.
To compare Delta and Omicron, London data was selected from a week where Delta was dominant.

The initial analysis found no clear differences in the early symptoms (three days after test) between Delta and Omicron.
However, five common symptoms did emerge in the region, which, due to the dominance of Omicron, are most likely attributed to the variant over its predecessor.
The “top five” symptoms reported in the ZOE app were:
ZOE will be conducting further research into the symptom profile of Omicron in the coming weeks.

According to ZOE COVID Study incidence figures, in total there are currently 87,131 new daily symptomatic cases of Covid in the UK on average, based on PCR and LFT test data from up to five days ago. An increase of four percent from 83,658 new daily cases last week.
In the vaccinated population (at least two doses) there are currently 27,000 new daily symptomatic cases in the UK. An increase of six percent from 25,411 new daily cases last week.
In terms of prevalence, on average one in 57 people in the UK currently have symptomatic Covid. In the regions, England, one in 56. Wales, one in 46. Scotland, one in 79.
In the regions, cases are rapidly increasing in London, a rise being driven by Omicron.In the regions, cases are rapidly increasing in LondonThe number of daily new cases among 0-18 year-olds remains high, while cases in the 19-35s are rapidly rising and the 36-55 age group continue to rise more steadily.
Cases in the 55-75 age group are dropping and cases remain low in the over 75s, likely due to third dose vaccines but also a change in behaviour such as face mask wearing and avoiding large social gathering which we expect is being driven by fear of Omicron.
The ZOE COVID Study incidence figures (new symptomatic cases) are based on reports from around 750,000 weekly contributors and the proportion of newly symptomatic users who have received positive swab tests.
The latest survey figures were based on data from 52,489 recent swab tests done in the two weeks up to 11th December 2021.How Covid compares with the fluProfessor Tim Spector, lead scientist on the ZOE COVID Study app, comments on the latest data: “Omicron is set to be the dominant strain in the UK by Christmas, and in the New Year cases could hit a peak higher than anything we’ve ever seen before.
“In London cases have been rising rapidly, but this will likely slow down soon, as people change their behaviour, such as wearing face masks again, cancelling parties and working from home more. Hopefully people now recognise the cold-like symptoms which appear to be the predominant feature of Omicron. These are the changes that will slow the spread of the virus. It’s my hope that the rest of the country is doing the same to avoid big outbreaks outside of London, especially in big cities.”
He continued: Ahead of Christmas, if people want to get together and keep vulnerable family members safe, I’d recommend limiting social contact in the run up to Christmas and doing a few Lateral Flow Tests just before the big family gathering. As our latest data shows, Omicron symptoms are predominantly cold symptoms, runny nose, headache, sore throat and sneezing, so people should stay at home as it might well be Covid.
“We are also seeing two to three times as many mild infections in people with boosters in Omicron areas as we do in Delta variant areas, but they are still very protective and a vital weapon. The ZOE app is one of the best tools we have to rapidly understand this new variant so we want to encourage everyone to download the app and start logging. It only takes a minute to report but each contribution makes a huge difference to the fight against Covid.”
