Across the UK there has so far been 502,978 positive cases.
Of those, England accounts for 430,843 cases with a rate of 765.4 per 100,000 people.
In comparison, Scotland has 32,209 cases with a rate of 589.6 per 100,000 people while Northern Ireland has 14,074 cases with a rate of 743.2 per 100,000 people.
Wales accounts for 25,852 cases with a rate of 819.9 per 100,000 people.
These latest figures come as the weekly rate of new Covid-19 cases has soared in dozens of areas of England, following the addition of nearly 16,000 cases that went unreported by because of a technical error with an Excel spreadsheet.
The problem has led to a delay in efforts by NHS Test and Trace to find the contacts of those who tested positive for the virus, in some cases by around a week.
Prime Minister Boris Johnson was unable to say on Monday morning how many contacts of positive coronavirus cases had been missed.
Analysis shows the North West to have some of the worst infection rates in the country.
Manchester now has the highest rate in England, with 2,740 cases recorded in the seven days to October 1 – the equivalent of 495.6 cases per 100,000 people, up from 223.2 in the previous week.
Liverpool has the second highest rate, up from 287.1 to 456.4, with 2,273 new cases and Knowsley in Merseyside is in third place, up from 300.3 to 452.1, with 682 new cases.
The analysis, based on Public Health England data published on Sunday night, also shows sharp rises in Newcastle upon Tyne, Nottingham, Leeds and and Sheffield
It comes as scientists raised concerns that potentially thousands of people who are contacts of those with Covid-19 may have spread the virus in the last week.
The issue occurred when people who tested positive were not recorded once a master Excel spreadsheet reached its maximum size.
Public Health England (PHE) said the technical issue resulted in 15,841 cases between September 25 and October 2 being left out of the reported daily coronavirus cases.
It said the outstanding cases were transferred to NHS Test and Trace “immediately” after the issue was noted and all cases were passed on to tracers by 1am on Saturday.
The Excel spreadsheet reached its maximum file size, which stopped new names being added in an automated process, it is understood.
The files have now been split into smaller multiple files to prevent the issue happening again.
PHE said every single person who was tested initially had received their test result as normal, with all those testing positive told to self-isolate.
The number of call attempts to contacts of those affected is being increased from 10 to 15 over 96 hours.
Asked on Monday how many contacts of positive coronavirus cases had been missed as a result of the error, Mr Johnson told reporters in central London: “I can’t give you those figures. What I can say is all those people are obviously being contacted and the key thing is that everybody, whether in this group or generally, should self-isolate.”
He said the updated figures meant that the prevalence of the virus was where experts had expected it to be and it would soon be apparent if extra restrictions were having the intended impact.
“The incidence that we are seeing in the cases corresponds to pretty much where we thought we were,” he said.
“And, to be frank, I think that the slightly lower numbers that we’d seen, you know, didn’t really reflect where we thought the disease was likely to go, so I think these numbers are realistic.”
Shadow health secretary Jonathan Ashworth said the error was “shambolic”, adding that “people across the country will be understandably alarmed.”
Health Secretary Matt Hancock is to make a Commons statement on Monday afternoon on the issue.
