One in 35 people in the country have been affected by Omicron, which has helped drive Covid rates to record highs in England.
According to the Office for National Statistics, almost 3% of England's population had Covid between 13 and 19 December, with infections higher than last week in all regions except the south-west.
In the week studied, the highest rate of Covid was in London, and the lowest in the north-eastern part of the country.
The ONS said that the results of the new test rose in all regions of England, and in all nations of the UK, compared with last week.
The rise in infections was across almost all age groups, with the figures suggesting the rapid spread of omicron was a significant factor in recent trends.
