Covid-19 infections continue to increase

Covid-19 infections are continuing to rise in all four nations of the UK, with the increase likely to be driven by the latest Omicron variants BA.4 and BA.5, figures show.

The number of people in hospital with Covid is also on an upward trend in most parts of the country, suggesting the virus is becoming steadily more prevalent.

Health experts said that while there is "currently no evidence" that

A total of 1.7 million people in private households are estimated to have had the virus last week, up 23% from 1.4 million a week earlier, according to the Office for National Statistics (ONS).

The rise of 23% is lower than the 43% jump in the previous week's figures, but it means total infections are now at levels last seen at the end of April.

They are also higher than the peak reached during the second wave of the virus in January 2021.

However, infections are still below the record 4.9million seen at the peak of the Omicron BA.2 wave at the end of March this year.

The ONS said the latest increase was "likely caused by infections compatible with Omicron variants BA.4 and BA.5", which are now thought to be the most dominant strains in much of the UK.

The virus continues to be most prevalent in Scotland, where 250,700 people were likely to test positive for Covid-19 last week, or one in 20.
