The first cases of coronavirus have been recorded at two hospitals in Norfolk after the infection spreads to all counties in the East of England.
Norfolk was the last county in the Anglia region to be free of coronavirus until Saturday when three cases were confirmed at the Queen Elizabeth Hospital in King's Lynn and a single case at the Norfolk & Norwich University Hospital.
Before the cases in Norfolk were confirmed, the latest daily figures issued by Public Health England on Saturday revealed 51 cases of infection in the Anglia region, and increase of six since Friday.
The highest concentration of confirmed coronavirus infections is in the south of the region, in Hertfordshire and Essex, where the first cases in the East of England were recorded.
Ten more patients have died in England after testing positive for Covid-19, bringing the UK death toll to 21.
Of the 10 patients who died since Friday, a number of them, who were over 60, had underlying health conditions.
There have been 1,140 positive tests for coronavirus in the UK as of 9am on Saturday, up from 798 at the same time on Friday.
The case of coronavirus that was confirmed at the Norfolk and Norwich University Hospital was in a patient already being treated in isolation because the infection was suspected.
In an email to staff, the hospital said: "This is our first confirmed case of Covid-19 in the hospital and we have robust and well-prepared plans in place."
It comes as plans get under way to ban mass gatherings from next week as the Government looks to implement more extreme measures in the fight against Covid-19.
Boris Johnson had faced criticism for not taking such actions, despite similar steps being taken by other European countries as the pandemic worsens.
Emergency legislation bringing in beefed-up powers will be published next week and there could also be a move towards more people working from home, a Whitehall source said.
