Covid-19 infections in the UK have fallen to their lowest level for two months, in fresh evidence the current wave of the virus is receding, figures show.

The number of patients in hospital with the virus is also continuing to drop, though health experts warned infections are likely to rise again in the autumn and winter.

A new booster jab will be offered to everyone in the UK aged 50 and over from next month, as well as those with underlying health conditions, to increase protection ahead of the future waves of the virus.

The latest estimate for people testing positive in Scotland is 164,100, or around one in 30, down from 260,800 in late July, or one in 20.

A total of 1.7 million people in private households are estimated to have had Covid-19 in the week to August 8, according to the Office for National Statistics (ONS).

This is a drop of 34% from the previous estimate of 2.6 million for the week ending July 26.

Sarah Crofts, head of analytical outputs for the ONS Covid-19 infection survey, said: “Infections have continued to fall across much of the UK to levels last seen in mid-June.

“Our latest data show these decreases are among nearly all ages in England, with the lowest levels seen among children.

“We will continue to monitor the data closely to understand the impact of the summer holidays.”

The current wave has been driven by the Omicron BA.4 and BA.5 subvariants of the virus and saw weekly infections climb as high as 3.8 million in early July.

This was not as steep as the record 4.9 million infections at the peak of the Omicron BA.2 wave in late March, however.

Some 1.4 million people in England were likely to have tested positive for Covid-19 in the most recent week of the survey, the equivalent of around one in 40, the ONS said.

This is down from 2.1 million, or one in 25, in late July.

In Wales, infections stood at 72,600 in the week to August 8, or one in 40 people, compared with 108,800, or one in 30, in the previous survey.

In Northern Ireland infections were estimated to be 36,600 in the week to August 8, or one in 50 people, down sharply from 109,800, or one in 17.

Separate figures show the number of people in hospital who have tested positive for Covid-19 is continuing to drop.

There were 7,421 patients with the virus in hospitals in England on August 18, down 11% week on week, according to NHS data.

It is a similar picture in Scotland, Wales and Northern Ireland, where patient levels are on a downward trend after rising for much of June and the early part of July.

High levels of coronavirus antibodies among the population – either from vaccination or previous infection – mean the number of people seriously ill or dying from the virus this year remains low.

Dr Mary Ramsay, director of clinical programmes at the UK Health Security Agency, said: “It’s very encouraging that Covid-19 case rates and hospitalisations are now at low levels.

“We expect them to remain low over the coming weeks before rising again as we head into the autumn and winter.

“Vaccines continue to provide the best defence against serious illness and hospitalisation with Covid-19.

“Plans are well under way for the rollout of the autumn booster programme and we urge all those eligible – people aged 50 and over and those with underlying health conditions – to come forward when called to have the maximum protection against Covid-19.”
