An inmate being held at a prison near the Staffordshire/Derbyshire border has died after testing positive for Covid-19.
A 70-year-old held at HMP Sudbury died in hospital on Sunday, a Prison Service spokesman said.
Ten prisoners have now died after contracting coronavirus, the Ministry of Justice said.
Three were inmates at HMP Littlehey, Cambridgeshire, with others being held at Birmingham, Manchester, Altcourse in Merseyside, Belmarsh in south-east London, Whatton in Nottinghamshire and a female prisoner at Low Newton, County Durham.
A total of 116 prisoners have tested positive for coronavirus in 43 prisons as of 5pm on Monday, the Ministry of Justice said.
The first case of a prisoner testing positive in the UK Prison network was at HMP Oakwood in the south of Staffordshire.
There are 19 prison staff in 12 jails who have contracted the virus, as well as four prison escort and custody services staff.
A total of six pregnant inmates have been released from prison so far in a bid to protect them from coronavirus.
Suitable accommodation was being found for them before they were released, the Justice Committee said in a tweet while it was hearing evidence from Justice Secretary Robert Buckland in private on Tuesday afternoon.
There are currently 35 pregnant prisoners and 34 inmates in mother and baby units across 12 prisons in England – the Press Association reports.
Responding to news that six pregnant inmates have been released from jail so far, the Women in Prison charity said: “Failure to act with urgency to drastically reduce the number of people in prison will have a devastating impact on all of our communities.
“The Government is taking too long to release pregnant women and those on mother and baby units from prison.
“Now is not the time for complacency, the Government must act fast to release the remaining pregnant women and many more people from prison with the housing and support they need.
“The Government need to demonstrate leadership on this crisis. Further inaction will result in more avoidable deaths both inside and outside of prison and a public health catastrophe.”
