More than two-thirds of local areas across England are seeing a rise in Covid-19 case rates.
Seven days ago, 126 out of a total of 315 local authority areas had recorded a week-on-week jump in rates.
That figure now stands at 222.
There is considerable variation in the level of rates among the different regions of England, however.
There are also a number of local areas currently in Tier 3 where rates have dropped steeply – and areas in Tier 2 where they have risen sharply.
The Government has already announced that London and parts of Essex and Hertfordshire are moving from Tier 2 to Tier 3 from 12.01am on December 16.
Other changes could be announced this week following a review on Wednesday of the current system of tiers.
Here is a region-by-region guide to all the latest figures, including the areas recording the biggest week-on-week rise and fall.
In all instances, the rates are for the week ending December 10 and have been calculated by the PA news agency using data published by Public Health England.
– North-east England
This is currently the only region in England entirely in Tier 3 of the Government's Covid-19 restrictions.
Case rates had previously been dropping in all local areas, but the latest figures show increases in four places: County Durham, Middlesbrough, South Tyneside and Redcar & Cleveland.
Rates overall are at a lower level than much of southern England, however.
The biggest week-on-week rise is in South Tyneside, up from 215.3 cases per 100,000 people to 274.9.
This is also the highest rate in the region.
North Tyneside has seen the biggest fall, down from 152.9 to 125.1.
The lowest rate is in Gateshead: 92.1, down from 107.4.
– North-west England
Most of north-west England has been in Tier 3, with some notable exceptions: the six local authorities within the Liverpool City Region; Warrington; Cheshire East; Cheshire West & Chester; and all the local authorities in the county of Cumbria. All of these have been in Tier 2.
Rates are up in just over half of all local areas in the region – 22 areas out of 39.
But, as with north-east England, rates across this region are typically lower than most areas in the southern half of the country.
Ribble Valley (Tier 3) has seen the biggest week-on-week jump, up from 139.6 to 197.1.
The biggest fall is in Pendle (also Tier 3), down from 289.9 to 233.4.
Burnley (Tier 3) has the highest rate in the region – 298.0, up from 265.4.
Copeland in Tier 2 has the lowest: 22.0, down from 44.0.
– Yorkshire & the Humber
Almost the whole of this region has been in Tier 3, except for the city of York and the county of North Yorkshire, which have been in Tier 2.
Rates are down across the region except in three local areas: Rotherham, Ryedale and Selby.
In each case the week-on-week increase is very small, however.
Rotherham, which is in Tier 3 and has seen the biggest jump, is up from 189.9 to 220.0.
This is also the highest rate in the region.
North East Lincolnshire, also in Tier 3, has recorded the biggest fall, from 180.5 to 115.3.
Hambleton (Tier 2) has the lowest rate – 48.0, down from 63.3.
– West Midlands
A week ago, every area in the West Midlands was recording a fall in rates, with one exception: Staffordshire Moorlands.
The latest figures show increases in 17 of the 30 areas in the region (including Staffordshire Moorlands).
Warwick (currently in Tier 3) has seen the largest rise, up from 104.3 to 180.2.
The biggest week-on-week drop is in Stoke-on-Trent (also Tier 3), down from 353.4 to 295.3 – though this is still the highest rate in the region.
Herefordshire, Shropshire and Worcestershire are currently in Tier 2; the rest of the West Midlands is in Tier 3.
The lowest rate in the West Midlands is in Malvern Hills (Tier 2) – 39.4, down from 63.5.
– East Midlands
As with neighbouring West Midlands, a majority of areas in the East Midlands are now recording a rise.
A total of 23 of the 40 local authority areas have seen rates increase in the latest figures.
The steepest jump is in South Derbyshire, currently in Tier 3, where the rate has risen from 127.7 to 249.9.
South Kesteven (also Tier 3) has seen the biggest fall, down from 211.3 to 172.0.
All of the East Midlands is currently in Tier 3, except for the county of Rutland and all local authority areas in Northamptonshire.
Rutland is one of the Tier 2 areas where rates have risen, however, along with Corby, East Northamptonshire, Northampton, South Northamptonshire and Wellingborough.
Lincoln (Tier 3) has the highest rate in the region: 479.4, up from 381.7.
Derbyshire Dales, also in Tier 3, has the lowest: 76.0, down slightly from 80.2.

– Eastern England
The whole of eastern England has been in Tier 2.
But from 12.01am on Wednesday December 16, 11 local authority areas in Essex and four in Hertfordshire will be moving into Tier 3.
All of these areas have seen a week-on-week rise in rates, along with every other local area in the region – with three exceptions: North Norfolk, South Norfolk and Stevenage.
These three areas have seen very small decreases.
Basildon has recorded the biggest week-on-week increase, where the rates have soared from 391.0 to 643.2.
It is one of the areas that will be moving from Tier 2 to Tier 3 on Wednesday, and is also the highest rate in the region.
North Norfolk (Tier 2) has the lowest rate: 57.2, down from 66.8.
– South-east England
Rates are rising in all but five of the 67 local authority areas in south-east England.
Currently 14 areas in the South East are in Tier 3, comprising the county of Kent plus Slough in Berkshire.
Everywhere else is in Tier 2, except the Isle of Wight, which is in Tier 1.
No changes to these levels of restrictions have so far been announced.
Ashford in Tier 3 has seen the biggest week-on-week increase, up from 220.7 to 496.8.
But the second biggest rise is in Hastings – currently in Tier 2 – up from 153.2 to 396.1.
The five areas where rates have fallen are Basingstoke & Deane, the Isle of Wight, Runnymede, Thanet, and Winchester.
South-east England is notable for containing both the highest and the lowest rates in the whole of England – Swale (Tier 3), currently on 671.6 cases per 100,000; and the Isle of Wight (Tier 1), currently on 14.1.
– South-west England
Of the 29 local authority areas in south-west England, 18 have recorded a rise in the latest figures.
They include two of the three areas of the South West that are in Tier 3 – North Somerset and South Gloucestershire.
In the other Tier 3 area, Bristol, the rate has dropped slightly from 140.7 to 115.0.
Forest of Dean (currently in Tier 2) has seen the biggest rise of anywhere in the region, up from 68.0 to 184.4.
South-west England includes the only other area in England, along with the Isle of Wight, that is in Tier 1 – Cornwall & the Isles of Scilly.
Here the rate currently stands at 20.6, down from 25.9 and the lowest in the region.
Gloucester (Tier 2) has the highest rate, up from 159.5 to 222.3.
London will move from Tier 2 to Tier 3 at 12.01am on December 16.
The latest figures show rates are rising in all 32 local areas, with the biggest jump in Havering – up from 348.3 to 540.9.
This is also the highest rate anywhere in London, and the fourth highest in the whole of England.
Westminster has the lowest rate – 131.6, up from 91.5.
A total of 15 of the top 50 highest rates in England are currently in London.
