COVID-19 infection levels dropped last week in all nations of the United Kingdom except Northern Ireland, the Office for National Statistics (ONS) has said.
Its data suggests the latest wave of coronavirus, with the dominant Omicron variant, may have peaked.
The figures cover people in private households estimated to have had COVID-19 in the seven days to 15 January.
In England, one in 20 are believed to have been infected – around three million people, down from 3.7m in the week to 6 January.
In Scotland, it was also one in 20, or 236,600 people, down from 297,400.
In Wales, the estimate is one in 25, or 112,100 people, down from 169,100.
But in Northern Ireland, there was a slight increase – up to 104,300, from 99,200.
The proportion estimated to be infected, however, is one in 20, the same as in England and Scotland, and the ONS said the trend in Northern Ireland is “uncertain”.
