The UK reported a massive 226,524 additional cases of Covid on Monday, while weekly infections rose by 37 percent.
The latest daily figure is the highest ever recorded in the UK, but includes positive tests recorded over the weekend.
The number is more than 50,000 higher than the 170,985 cases reported last Monday.
Some 607,737 cases have been reported in the past seven days, which is 36.8 percent higher than the number of confirmed infections in the past seven days.
On Monday, a further 169 deaths were reported within 28 days of a positive Covid test, bringing the official death toll in the UK to 163,679.
An additional 786 deaths were reported in the past week, 60 more than the previous seven days – an increase of 8.3 percent.
The number of hospitalized patients with Covid is also increasing, with 12,507 admitted in the past seven days, 2,506 – or 25.1 percent – more than the previous seven days.
However, the number of seriously ill patients on ventilator remains relatively stable. About 287 people were reported to need mechanical ventilation on Monday, which is well below the Omicron wave peak in November, when more than 1,000 were on ventilators on several days.
It comes after it was revealed that the number of patients in hospital in Scotland with Covid-19 has reached the highest since the start of the pandemic.
About 300,000 people a day in the UK describe symptoms of Covid and experts think there could be three million active cases in the UK, due to Omicron’s more contagious BA.2 subvariant and the ending of restrictions.
More than 11,500 hospitalized patients in England have tested positive for Covid, but Health Minister Sajid Javid said “60 percent are not there because of Covid” but happen to be carrying the virus.
Speaking on Monday, Mr Javid said they were “still well below their peak” despite the increase in cases. He said: “There is no cause for concern at this time.”
On Monday, a fourth dose of vaccine was rolled out for five million people – people over 75, who live in retirement homes or with suppressed immune systems.
A fourth dose will probably be offered to all people aged 50 and older in the autumn, but a final decision has not yet been made by the Joint Committee on Vaccination and Immunization (JCVI).
