There have been 10.4 million confirmed cases of coronavirus in the UK and more than 145,000 people have died, government figures show.
However, these figures include only people who have died within 28 days of testing positive for coronavirus.
So far, 89% of people aged 12 and over in the UK have had their first vaccine dose, 81% have had their second and 34% have had a booster.
Find out how the pandemic has affected your area and how it compares with the national average:
Daily cases remain high
The average number of daily confirmed cases has bounced around since mid-July and has been rising again since early November.
A further 42,848 confirmed cases were announced on Saturday.
The emergence of the new Omicron variant means new temporary measures are being put in place as a precaution.
It is thought the infection rate in the first peak of the virus in spring 2020 was much higher than was evident from the reported number of cases. Testing capacity was then too limited to detect the true number of daily cases.
The red areas on the map below show the places currently seeing the highest number of cases per 100,000 people.

Vaccine rollout continuing
More than 51 million people, 89% of those aged 12 and over in the UK, have now received a first dose of a vaccine.
The number of people who have received a second vaccine dose is now more than 46 million, or 81% of people aged 12 and over.
So far, nearly 20 million booster doses have been administered across the UK, with 16.6 million in England, 1.8 million in Scotland, 900,000 in Wales and 400,000 in Northern Ireland.
Prime Minister Boris Johnson has said there are "good reasons" to believe the vaccines will provide at least some protection against the new Omicron variant.
"If you're boosted, your response is likely to be stronger so it's more vital than ever that people get their jabs and we get those boosters into arms as fast as possible," he said.
The booster campaign, for people aged over 40 or belonging to a number of other groups, is now being extended to all over-18s.
Daily deaths have been falling
There were 127 deaths within 28 days of a positive test reported on Saturday.
Of those deaths, 104 were in England, 14 were in Scotland and nine were in Northern Ireland. No deaths were reported in Wales.
England has seen the majority of UK deaths since the pandemic began, with more than 126,000 so far.
Hospital numbers stable
The most recent government figures show 7,373 people with coronavirus in hospital in the UK, down from 7,653 a week earlier.
Although numbers of hospital patients with coronavirus are higher than they were over the summer, they are far below the peak of nearly 40,000 people back in January.
Looking at Covid patients in hospital by region, the numbers are higher than in the summer but have been falling slowly in some regions.
Death toll could be nearly 170,000
When looking at the overall death toll from coronavirus, official figures count deaths in three different ways, each giving a slightly different number.
First, government figures - the ones reported each day - count people who died within 28 days of testing positive for coronavirus. This figure is more than 145,000.
According to the latest ONS figures, the UK has now seen more than 169,000 deaths in total - that's all those deaths where coronavirus was mentioned on the death certificate even if the person had not been tested for the virus.
The third measure counts all deaths over and above the usual number at the time of year - that figure was more than 140,000 as of 19 November.
In total, there were 13,743 deaths registered in the week to 19 November, which was 16% above the five-year average.
Of the total deaths, 1,088 were related to coronavirus, fewer than the previous week.
There have been more deaths involving Covid than "excess" deaths since the start of the pandemic, meaning non-Covid deaths must be below usual levels.
This could be down to the milder flu season last winter - due to less travel and more social distancing - and because some people who might have died for other reasons had there been no pandemic, died of Covid.
What is the R number?
The "R number" is the average number of people an infected person will pass the disease on to.
If R is below one, then the number of people contracting the disease will fall; if it is above one, the number will grow.
The government has said in the past that the R number is one of the most important factors in making policy decisions.
The latest R number estimate for England is 0.9 to 1.1, for Scotland it is 0.8 to 1.1, for Wales it is 0.8 to 1.0 and for Northern Ireland it is 0.9 to 1.0.
