Scientists estimate 47,000 daily Covid cases in EnglandAround 47,000 Covid-19 infections are occurring each day across England, with daily deaths expected to hit 240 to 690 by 26 October, according to evidence presented to government scientists.
The Medical Research Council (MRC) biostatistics unit at Cambridge University published new predictions this week on how fast the epidemic is growing across the country.
It estimates cases are doubling in under seven days, with a "substantial proportion" of those being asymptomatic.
The figures are fed to the Scientific Pandemic Influenza Group on Modelling, which provides real-time information to the government through the Scientific Advisory Group for Emergencies (Sage), and to regional Public Health England (PHE) teams.
On 12 October, the MRC unit published a report saying: "Our current estimate of the number of infections occurring each day across England is 47,000.
"We predict that the number of deaths each day is likely to be between 240 and 690 on 26 October."
It said the daily number of infections was within the range of 28,900 to 74,900, with the best estimate being 47,000, and said the number of new infections is particularly high in the north-west of England, north-east of England and Yorkshire, followed by London and the Midlands.
It added the estimated growth rate for England was 0.09 per day.

The ban will cover all of Northern Ireland, England's tier two and three areas and the Scottish central belt.

Greater Manchester mayor wants 'fairness' for workersThe UK's foreign secretary has said Greater Manchester's mayor should "do the right thing by the people" and agree to the highest level of Covid measures.
Dominic Raab said Labour's Andy Burnham was "effectively trying to hold the government over a barrel over money and politics".
Burnham later tweeted: "It's not about what we want for ourselves, Dominic Raab. It's about what we want for low-paid and self-employed people everywhere: fairness."
On Thursday, Burnham said Greater Manchester would "stand firm" against plans to move it into Tier 3, calling it a "flawed" and "unfair" policy.
He wants more financial support for people affected by tougher rules.
Meanwhile, discussions between central government and local leaders over putting the region into Tier 3 have stalled.
Speaking to BBC Breakfast earlier, Sir Richard Lees, the leader of Manchester City council, said no talks were planned for Friday.
He said that "at the moment there are no meetings in the diary between us and government", adding: "We are in a bit of a vacuum."

One-way Australia-New Zealand 'bubble' opensAs we reported earlier, the first passengers from New Zealand have arrived in Australia under new "travel bubble" arrangements between the two countries.
None of the passengers will have to quarantine on arrival in Sydney, though they will have to do so on returning to New Zealand.
Australia and New Zealand are among the first countries in the Asia-Pacific region to loosen restrictions on international travel since Covid-19 travel bans came into effect earlier this year.
Since March, Australia's borders have been closed to everyone except returning Australian citizens and residents and those with special permission.
Swiss yodelling concert creates European hotspotIn Switzerland, a yodel concert attended by 600 people is believed to have made one canton a European virus hotspot.
According to the authorities, people at the event, which took place at the end of September in the rural canton of Schwyz, were asked to keep their distances, but were not required to wear masks.
"We found out nine days after the performance that several people from the group were infected," event organiser Beat Hegner told Swiss television.
With more than 1,230 coronavirus cases, the canton is now one of the continent's hotspots.
"The explosion in the number of cases in Schwyz is one of the worst in all of Europe," local hospital chief Reto Nueesch is quoted as saying in local media.
On Wednesday, some 94 people tested positive, twice as many as the day before, and 114 on Thursday.
