NHS England data shows 41 people were being cared for in hospital by the trust on Tuesday, August 17.
The number of beds at Sherwood Forest Hospitals NHS Trust occupied by people who tested positive for Covid-19 increased more than eight-fold, from five on May 18 – the day after pubs and restaurants were allowed to seat customers inside and the cap on outdoor gatherings was raised to 30 people.
Last month, the fourth and last step of the Government's roadmap was also reached, when capacity limits for venues and events were scrapped and social distancing rules ended.
The figures show the number of people being treated in hospital for Covid on August 17 was up from 18 on the same day the previous week.
They also show 53 new Covid patients were admitted to hospital in SFH hospitals – Mansfield Community, Sutton’s King’s Mill and Newark – in the week to August 15, an increase from 32 the previous week.
Majority of adults vaccinated
Across England, there were 5,437 people in hospital with Covid as of August 17, with 825 of them in mechanical ventilation beds.
The number of Covid-19 patients hospitalised nationally has increased more than seven-fold since May 18 and is 40 per cent higher than it was four weeks ago, when 3,894 people were in hospital with the virus.
Prof Chris Whitty, England’s chief medical officer, has urged people not to delay getting their Covid-19 vaccine, warning there were some “very sick” young adults in hospital with the virus.
His comments came as separate figures from Public Health England showed 55 per cent of people in hospital with the Delta variant – which is dominant in the UK – have not been jabbed.
Of the coronavirus patients aged under 50, 74 per cent had not received a vaccination, while almost two-thirds of people who died were not jabbed.
Prof Whitty said: “The majority of adults have been vaccinated.
“Four weeks working on a Covid ward makes stark the reality that the majority of our hospitalised Covid patients are unvaccinated and regret delaying – some are very sick, including young adults.”
The UK’s vaccine programme has so far seen about three-quarters of adults in the UK double-jabbed.
