A new interactive map shows where the next coronavirus hotspots are likeliest to flare up in the next three weeks.
The Imperial College London document highlights areas across England and Wales where infections are increasing.
Breckland, a local authority in Norfolk, looks likely to be a high-risk area in just a fortnight, the data suggests.
Other areas seeing a rise in cases are all in the north of England, such as Bolton, Rossendale in Lancashire and Leeds in West Yorkshire.
South Tyneside in Tyne and Wear and Pendle, Lancashire – which are already seeing spikes – are expected to remain high, according to the map.
Professor Axel Gandy, from the Department of Mathematics at Imperial, said ‘The model allows us to project where local hotspots of Covid-19 are likely to develop in England and Wales based on the trends that we are seeing in those areas.
‘Covid-19 is, unfortunately, very much still with us, but we hope this will be a useful tool for local and national governments trying to bring hotspots under control.’
Researchers at Imperial said they ‘define a local authority to be a hotspot if weekly reported cases per 100,000 population exceed 50’.
The team used data on daily reported cases, weekly reported deaths and mathematical modelling to report the probability a local authority will become a hotspot in the following week.
The site also provides estimates for each local authority in England and Wales on whether cases are likely to be increasing or decreasing in the following week.
Britain has recorded another 17 coronavirus deaths on Thursday in the preliminary count
The predictions assume no change in current interventions – such as lockdowns, and school closures – in a local authority beyond those already taken about a week before the end of observations.
The team notes an increase in cases in a local authority can be due to an increase in testing, which the model does not currently account for.
The model also assumes all individuals within each local authority are equally likely to be infected, so demographic factors such as the age structure of the population are not considered.
Dr Swapnil Mishra, from the MRC Centre for Global Infectious Disease Analysis, added: ‘We provide weekly predictions of the evolution of Covid-19 at the local authority level in England and Wales.
‘Our model helps to identify hotspots – probable local areas of concern. We hope that our estimates will enable swift action at the local level to control the spread of the epidemic.’
It is likely Pendle and Bolton will remain hotspots for the next two weeks, according to modelling by Imperial College London. Researchers led by Professor Axel Gandy have today revealed a website which estimates the probability that a location in England will be struck down with high Covid-19 cases, based on current data
In the week between September 6 and 12, the areas highlighted red are likely to become Covid-19 hotspots, with more than 50 cases per 100,000. All the affected areas are captured. Red is 75-100 per cent chance, dark orange is 50-75 per cent, and light orange is 25-50 per cent
By September 13 to 19, there could be dozens more areas that are hotspots, including South Tyneside (97 per cent), Rossendale (90 per cent), Leeds (85 per cent), Corby (81 per cent) and Breckland (81 per cent). All affected areas are captured
The team behind the website define a hotspot as a local authority where there are more than 50 cases of Covid-19 per 100,000 of the population per week.
Currently Pendle, Bolton, Corby and Oldham fit into this category. But in the next, two weeks, dozens more appear to join the list while others fall off.
Where are England’s 20 Covis-19 hotspots?
Local authorities new cases in the seven days to August 30 as a rate of per 100,000 people.
- Pendle 74.9
- Bolton 69.6
- Rossendale 65.8
- Oldham 63.3
- Corby 54.0
- Bradford 52.6
- Blackburn with Darwen 49.4
- South Tyneside 46.4
- Rochdale 44.1
- Manchester 42.7
- Tameside 39.3
- Trafford 38.8
- Salford 37.9
- Great Yarmouth 35.2
- Burnley 34.9
- Preston 33.5
- Leeds 32.5
- Kettering 32.4
- Breckland 31.4
- Birmingham 30.2
Imperial report the probability that a local authority will become a hotspot in a percentage – 100 per cent being almost certain.
South Tyneside (97 per cent), Rossendale (90 per cent), Leeds (85 per cent), Corby (81 per cent) and Breckland (81 per cent) all have the highest odds of seeing infections reach 50 per 100,000 people by mid-September.
But recently reported case numbers for Oldham show a decline, and as a result, the model shows it is unlikely Oldham will remain a hotspot into September (45 per cent), after several weeks of trying to squash outbreaks.
Various areas in London’s commuter belt have a medium chance of becoming a hotspot by September 19 – the furthest point of predictions modelled by Professor Gandy and team.
Waverley, in Surrey, and Hertsmere, in Hertfordshire, are 55 per cent and 61 per cent likely to see cases reach 50 per 100,000, respectively. They currently have 16.6 and 29 cases per 100,000.
Britain announced 1,735 new coronavirus cases on Thursday in the biggest daily spike in three months.
The last time daily infections were higher was on June 4, when 1,805 were diagnosed with the disease and the majority of tough lockdown restrictions were still in force.
The seven-day rolling case average is now 1,435, up by a quarter (26 per cent) in a week.
Scotland is now also seeing new cases breach 100 every day, for the first time since May. First Minister Nicola Sturgeon revealed today the country’s reproduction rate could be as high as 1.4, after months of it being safely underneath 1.
The R rate – which represents the average number of people each Covid-19 patient infects – needs to stay below one or it could spiral uncontrollably.
For Britain as a whole, the R is thought to be hovering around the danger zone of 1 and SAGE is no longer confident is definitely below that number.
