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

There have been more than 830,000 confirmed cases of coronavirus so far in the UK and nearly 45,000 people have died, government figures show.

However, these figures include only people who have died within 28 days of testing positive for coronavirus and other measures suggest the number of deaths is higher.

The government announced 23,012 confirmed cases on Saturday.

After a steady decline since the first peak in April, confirmed cases started rising again in July, with the rate of growth increasing sharply from the end of August.

The Scientific Advisory Group for Emergencies (Sage) has said it is "almost certain that the epidemic continues to grow exponentially across the country".

However, cases in the community may still be lower than during the first peak as widespread testing was not available until mid-May, meaning the number of cases recorded at the time was only a fraction of the people with coronavirus.

The most recent figures show hospital admission rates for Covid-19 patients rising most quickly in the North West and the North East and Yorkshire region.

With rising Covid-19 admissions, there have been warnings that hospitals will have to cut back core services.

Cases are rising quickly across large parts of England, with other spikes in areas of Scotland, Wales and Northern Ireland.

The orange areas on the map below are those currently seeing the highest number of cases per 100,000 people.

Restrictions have been tightened in many areas of the UK in recent weeks.

In England, a three-tier lockdown system has been introduced. On Saturday, South Yorkshire and Warrington joined Greater Manchester, Lancashire and Liverpool City Region in the highest level, tier three. Stoke-on-Trent, Coventry and Slough have moved into tier two.

Scotland is due to move to a five-tier system of virus alert levels from 2 November.

Wales has started a national lockdown, or circuit-breaker, meaning most non-essential businesses are closed and people are only able to leave home for limited reasons, until 9 November.

Northern Ireland has also introduced additional restrictions, including an extended two-week half term for schools.

The government announced 174 further deaths on Saturday.

Of those deaths, 141 were in England, 16 in Wales, 11 in Scotland, and six in Northern Ireland.

Three times as many people have died from Covid-19 than from flu and pneumonia in England and Wales this year, according to official figures.

Between January and August 2020, there were 48,168 deaths due to Covid-19 compared to 13,600 from pneumonia. Only 394 were due to flu.

Rules were amended over the 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 39,000.

When looking at the overall death toll from coronavirus, official figures count deaths in three different ways.

Government figures count people who tested positive for coronavirus and died within 28 days.

But there are two other measures.

The first includes all deaths where coronavirus was mentioned on the death certificate, even if the person had not been tested for the virus. The most recent figures suggest there had been more than 58,000 deaths by 9 October.

The second method looks at all UK deaths over and above the number usually expected for the time of year - known as excess deaths. This measure shows the death toll was more than 65,000 by 9 October.

There were 11,359 deaths registered in the UK in the week to 9 October, according to the latest figures reported by the Office for National Statistics.

Some 474 of these deaths involved Covid-19 - up by 131, or 38%, on the previous week's number.

However this represents only 5% of the peak of 9,495 deaths recorded in a week, reached on 17 April.

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.

On Friday, the government said its estimate for the R number across the whole of the UK was 1.2 - 1.4.

The estimate for England is 1.2-1.4, while for Scotland it is 1.2-1.5. The estimate for Wales is 1.1-1.4 and in Northern Ireland it is 1.4.

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