Covid-19 in the UK: How many coronavirus cases are there in your area?

There have been more than 4.1 million confirmed cases of coronavirus in the UK and more than 123,000 people have died, government figures show.

However, these figures include only people who have died within 28 days of testing positive for coronavirus.

More than 20 million people in the UK have now had their first dose of a coronavirus vaccine.

Cases declining

The number of daily infections in the UK continues to decline, with strict lockdown measures still in place across the country.

A further 6,391 confirmed cases across the UK were announced by the government on Tuesday.

This represents a decline of 25% on last Tuesday's figure of 8,489 new cases.

It is thought the infection rate was much higher than was evident from the reported number of cases during the first peak in spring last year. Testing capacity was too limited to detect the true number of daily cases.

The darker orange areas on the map below show the places currently seeing the highest number of cases per 100,000 people.

During the current lockdown, people have been told to stay at home, other than for limited purposes such as essential food shopping, medical appointments and work.

Prime Minister Boris Johnson has announced a "roadmap" for easing restrictions in England, starting with the reopening of schools on 8 March.

In Wales, stay-at-home rules will remain in place until at least 12 March, but some young children have started returning to school.

Younger children have also begun returning to school in Scotland, and on Tuesday the Scottish government announced secondary school pupils would also return part-time from 15 March.

First Minister Nicola Sturgeon said the government would also be considering if it was possible to speed up its plans to exit lockdown, with stay-at-home restrictions currently set to end on 5 April.

In Northern Ireland, children will begin a phased return to school this month, but other restrictions will continue until April.

Vaccine rollout continues

Health Secretary Matt Hancock says new evidence shows that the Oxford and Pfizer vaccines are "extremely effective" after one dose, reducing the chance of hospital care being needed by more than 80%.

More than 20 million people have now received a first dose of a vaccine, and over 800,000 people have had a second.

The current seven-day average for first doses is about 360,000 doses a day - down from more than 400,000 a day earlier this month.

This drop in first doses can be partially explained by an increase in the number of second doses now being administered.

Mr Hancock has blamed the reduction on supply issues, but has said the programme will see "some really bumper weeks in March".

In total, 17 million people in England have had one vaccine dose.

In Scotland, 1.6 million people have had their first dose, while the figure is about 925,000 in Wales and more than 525,000 in Northern Ireland.

The government is aiming to offer a vaccine to everyone in the top nine priority groups, including care home residents, healthcare workers, people required to shield and everyone aged 50 and over, by 15 April.

After that, the rest of the adult population will be vaccinated, with people prioritised by age.

Mr Hancock said that an age-based strategy was "the way to save the most lives".

People in their 40s will be vaccinated, once the current first phase is completed.

All adults in the UK are expected to be offered their first dose of a coronavirus vaccine by the end of July.

Daily deaths also falling

The government announced a further 343 deaths within 28 days of a positive test on Tuesday.

On Tuesday last week, there were 548 deaths reported.

Of the latest deaths, 307 were in England, 33 in Scotland, two in Northern Ireland and one in Wales.

Rules were amended last summer to include deaths in the coronavirus total only if they occurred within 28 days of a positive test. Previously in England, all deaths after a positive test were included.

England has seen the majority of UK deaths from Covid-19. Using the 28-day cut-off, there have been more than 108,000.

Hospitals remain under pressure

There are more than 12,000 people with coronavirus in hospital in the UK.

Numbers in mid-January reached almost double the highest point of the peak last spring, but have been falling since then.

London, the South East and the Midlands saw the highest numbers in recent weeks, but patient numbers are falling in all UK nations and regions now.

But everywhere saw more patients in hospital in the latest surge than during the first wave last spring.

Death toll could be higher

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 count people who died within 28 days of testing positive for coronavirus - and that total is more than 123,000.

Second, ONS figures include all deaths where coronavirus was mentioned on the death certificate, even if the person had not been tested for the virus. This figure is more than 140,000 deaths, to 19 February.

The third measure counts all deaths over and above the usual number at the time of year - that figure was more than 120,000 by 19 February.

In total, there were 15,577 deaths registered in the week to 19 February, which is down on last week but still 18% higher than "normal" for the time of year.

Of that figure, 4,447 deaths were related to coronavirus - down by just over a quarter from the previous week.

There have now been more deaths involving Covid than "excess" deaths, which means non-Covid deaths must be below usual levels.

This could be because of a milder flu season - resulting from 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's current estimate for the R number across the whole of the UK is 0.6 to 0.9.

The estimates for England, Scotland and Wales are currently all 0.7 to 0.9 and in Northern Ireland it is 0.8 to 1.05

The government has said in the past that the R number is one of the most important factors in making policy decisions.
