Covid-19 infections in the UK have jumped by more than half a million in a week.
Figures also show the rise is likely to be driven by the latest Omicron variants BA.4 and BA.5.
Hospital numbers are also continuing to increase, with early signs of a rise in intensive care admissions among older age groups.
A total of 2.3 million people in private households are estimated to have had the virus last week, up 32% from a week earlier, according to the Office for National Statistics (ONS).
This is the highest estimate for total infections since late April, but is still some way below the record high of 4.9 million seen at the peak of the Omicron BA.2 wave at the end of March.
Sarah Crofts, ONS head of analytical outputs for the Covid-19 infection survey, said: “Across the UK we’ve seen a continued increase of over half a million infections, likely caused by the growth of BA.4 and BA.5 variants.
“This rise is seen across all ages, countries and regions of England.
“We will continue to monitor the data closely to see if this growth continues in the coming weeks.”
The virus remains most prevalent in Scotland, where 288,200 people were estimated to have had Covid-19 last week, or one in 18.
This is up week-on-week from 250,700, or one in 20, and is the highest estimate for Scotland since early April.
In England, 1.8 million people were likely to have had the virus last week, the equivalent of around one in 30.
This is up from 1.4 million, or one in 40, the previous week.
Wales has seen infections jump to 106,000, or one in 30, up from 68,500, or one in 45.
In Northern Ireland, infections have increased to an estimated 71,000 people, or one in 25, up from 59,900, or one in 30.
