The number of UK daily Covid cases has reached another record high – topping 200,000 for the first time.
The government said lab-confirmed coronavirus cases were 218,724 as of 9am on Tuesday, and a further 48 people had died within 28 days of testing positive for Covid.
On New Year’s Eve, 189,846 infections were reported – the previous high.
Tuesday’s figures contain some delayed reporting of cases because of the holiday period.
It comes as the NHS is facing significant pressure as it copes with the latest wave of Covid-19 despite hopes that cases should start to drop in the coming weeks.
Boris Johnson will lead a Downing Street press conference as No 10 admitted that the health service is facing a “difficult time” during a “challenging winter”.
But health secretary Sajid Javid said there was nothing in the data that suggested England needed to move beyond the current Plan B restrictions.
“I think Plan B, implementing that, has been the right approach and also being absolutely focused on the vaccination programme,” he told reporters during a visit to a vaccination centre in south London.
Officials in Whitehall are keeping an “extremely close eye” on hospital capacity, with admissions and occupancy “increasing significantly”, Downing Street said.
But the prime minister’s official spokesman said: “We’re not seeing that same jump in beds requiring ventilation, which is pleasing, and almost certainly a function of both the nature of Omicron and our successful booster programme.”
He added that the vaccinations and “evidence that Omicron may be milder” means “we are not seeing those huge waves in cases translate into those needing the most serious care that we saw perhaps in previous waves, but that still puts the NHS under significant pressure”.
The government has stuck with the Plan B measures in place in England – including wearing masks in shops and on public transport and working from home where possible – despite tougher restrictions in other parts of the UK.
That optimism may be helped by comments from Professor Neil Ferguson, from Imperial College London, whose data was instrumental to the UK going into lockdown in March 2020, who said infection rates may already be plateauing in London and could fall across the country within weeks.
Prof Ferguson, a member of the government’s Sage scientific advisory panel, told BBC Radio 4’s Today programme: “I would say that, with an epidemic which has been spreading so quickly and reaching such high numbers, it can’t sustain those numbers forever, so we would expect to see case numbers start to come down in the next week, maybe already coming down in London, but in other regions a week to three weeks.
“Whether they then drop precipitously, or we see a pattern a bit like we saw with Delta back in July of an initial drop and then quite a high plateau, remains to be seen.
“It’s just too difficult to interpret current mixing trends and what the effect of opening schools again will be.”
Prof Ferguson said the Omicron variant had not had much time to infect pupils before schools shut for the Christmas break, and a rise in cases is now expected.
Meanwhile, Professor Sir Andrew Pollard, director of the Oxford Vaccine Group, told Sky News it would not be “affordable, sustainable or deliverable” to give regular jabs every six months to cope with waning immunity and the rise of new variants.
“Remember that, today, less than 10% of people in low-income countries have even had their first dose, so the whole idea of regular fourth doses globally is just not sensible,” he said.
Sir Andrew said it may be that future boosters could be targeted at the most vulnerable and it is too early to say whether updated vaccines will be required every year, as with flu.
Downing Street said ministers will also be taking clinical advice and keeping a “very close eye on” the “waning efficacy of second doses and the interplay of Omicron on that as well” as part of a review on whether to make a booster jab a requirement to access a Covid pass.
Elsewhere, Matthew Taylor, chief executive of the NHS Confederation, said the staffing situation in hospitals is “almost impossible” as leaders try to manage their resources.
He told Times Radio that, for many, “the most pressing element of all” is the number of staff who are absent due to Covid.
He added that hospital admissions seem to have “perhaps plateaued in London or there may be a second peak after the new year now, but it’s rising across the rest of Britain”.
Meanwhile, Chris Hopson, chief executive of NHS Providers, said at least “half a dozen” NHS hospitals have declared a critical incident as they try to respond to Covid.
Morecambe Bay NHS Trust and Blackpool Teaching Hospitals NHS Trust were among those declaring critical incidents.
Dr Sakthi Karunanithi, public health director for Lancashire County Council, told Today: “Lancashire is beginning to experience what London did at the beginning of last month and, of course, London is better resourced and the infrastructures are well organised compared to other regions, so we are bracing ourselves for a tsunami of Omicron cases in Lancashire.”
Javid said it was a “fast-moving situation” but the NHS was getting “a huge amount of support” to cope with staff absences caused by the wave of coronavirus cases.
As well as volunteers the NHS is also “widely using an emergency list of workers that has been able to develop over the pandemic so far, and then call on clinicians and others that may have retired for example, to come back and help”, he said.
