Office for National Statistics weekly swabbing of 100,000 people estimated 2.03million had the virus on any given day over the week to December 23.
This marked a 70 per cent surge on the previous seven days, and was equivalent to one in 25 people having the virus. It was a record number of infections.
Cases were highest in epicentre London, where one in 15 people were estimated to be infected, followed by the South East and East of England, at one in 30. Cases were lowest in the North East at one in 45.
Separate data showed infections are now rising fastest among over-65s — the age group most vulnerable to the virus — where they are now doubling every week.
Experts said this would ‘directly feed’ into hospitalisations and that a spike was ‘certain’. But they added that the booster drive, which has reached 90 per cent of older adults, will provide an extra layer of protection.
The number of Covid patients in England’s hospitals yesterday broke through 11,000 for the first time since early February. And in London they have surged above 400 a day.
But a senior NHS boss today said there was no need for any new lockdown measures because Covid cases have remained stable. The chief executive of NHS Providers Chris Hopson added that the absence of a surge in hospitalisations of severly ill older people justified the Government’s current position.
Office for National Statistics random swabbing suggested 2million people in England had the virus last week — equivalent to one in 25. This was a 70 per cent surge in seven days, and the highest number on record
The Office for National Statistics carries out weekly surveillance of Covid infections across the country to estimate the prevalence of the virus.
Their study is seen as the gold-standard for tracking the outbreak by ministers because it can pick up infections among groups that are less likely to be tested for fear of having to self-isolate.
Across the four nations, cases were estimated to be rising fastest in Scotland, where they surged 70 per cent in a week from 76,200 to 135,400 people estimated to be infected on any given day last week.
This was followed by England and then Wales, where infections rose 40 per cent in a week to 76,500. In Northern Ireland they rose 26 per cent to 47,500 cases.
Have you REALLY hit your booster jab target, Boris?
Millions of eligible people in England have not had their Covid booster dose, official figures show – despite the Prime Minister insisting No10’s third dose target has been met.
Boris Johnson today bragged that the Government had achieved its goal of offering a top-up vaccine to all adults by the New Year.
But vaccination figures show 9.5million people who were double-jabbed by the end of September – and therefore now eligible for their third dose – have yet to get their booster.
Mr Johnson told the nation in a televised broadcast earlier this month that all eligible adults in England ‘will have the chance to get their booster before the New Year’.
No10 and the NHS subsequently clarified their goal was to invite eligible Britons for a vaccine before the end of the year, rather than deliver those doses.
ONS estimates of cases by age groups showed they were rising in all age groups, and ticking up fastest among 25 to 35-year-olds.
Statisticians said this matched testing data showing the virus was spreading fastest in this age group.
Separate figures from the Department of Health also showed the virus has now spilled over into over-65s, who are most vulnerable to the virus.
It publishes the infection rate for age groups broken down by five-year bands.
Among over-65s infections were rising fastest in 75 to 79-year-olds, surging 143 per cent in a week from 137.9 to 334.9 cases per 100,000 people.
They were followed by 80 to 84-year-olds, where cases surged 133 per cent from 107.8 to 250.8 cases, and 70 to 74-year-olds, where cases surged 131 per cent from 236.6 to 486. For 85 to 89-year-olds, cases are up 128 per cent in seven days, from 99.8 to 253, for the over-90s they are up 106 per cent, from 143.4 to 295.4, and among 65 to 69-year-olds they are up 103 per cent, from 236.6 to 486.
But the data showed cases were rising in every age group except 10 to 14-year-olds.
Scientists have said high levels of immunity in this age group from previous infections should keep the virus at bay, although a lack of testing because of the school holidays could also be behind the figures.
The surging infections in older age groups raise questions over whether the NHS could soon face an influx of admissions.
Professor Paul Hunter, an infectious diseases expert at the University of East Anglia, said it was ‘certain’ that there would be a spike in hospitalisations.
He told MailOnline: ‘The implications are clear that if infection rates continue to increase so quickly in the older age groups this will directly feed into higher hospitalisation rates from this age group.
‘But around 90 per cent of the over-65s have already had their booster dose so how high this increase will go is quite uncertain.’
He added: ‘I think it is absolutely certain that hospital admissions will spike. But the big questions are when will admissions peak and how high will they have got when they do.’
Latest data for hospitals in England shows there were more than 2,000 admissions on December 28, the latest available. This is the most since early February, and double the figure from a week ago.
Ministers have turbo-charged their booster drive and prioritised older groups in a bid to keep Omicron at bay, with scientists saying the jabs will provide an extra layer of protection.
And Boris Johnson claimed earlier this week that 90 per cent of Covid patients in intensive care had not received their booster jabs.
However, no figures have been published to back up this claim. Ministers today faced calls from Tory MPs to be transparent with their data.
The Government publishes daily figures on Omicron hospitalisations, but this is only broken down by whether people admitted have or have not received a Covid jab.
Officia figures show some 33million Britons have now got their booster jabs, or 58 per cent of the population.
Among over-65s 9.5million out of 10.7million have got their booster jabs — about 90 per cent.
Mr Hopson told The Times: ‘Although the numbers are going up and going up increasingly rapidly, the absence of large numbers of seriously ill older people is providing significant reassurance. But they are aware that this may change after the Christmas period.
‘Trust CEOs know that the government has a high threshold to cross before it will introduce extra restrictions and can see why, in the absence of that surge of severely ill older people, that threshold hasn’t been crossed yet.’
