It's been confirmed that Peter Gough died on Tuesday.
Peter, aged 56, was an Administration Assistant for the Oxford Univeristy Hospitals, supporting the delivery of patient care.
He most recently worked in Gastroenterology and Hepatology and before that in Neurosciences.
The Trust says Peter was a "well-liked colleague who was kind and caring" and an "asset to the team, who will be greatly missed."
Colleagues describe Peter as very hardworking, conscientious, always happy to help others out, and someone who enjoyed his job. They are being supported.
Terry Roberts, the Chief People Officer, says: "Our thoughts at this very sad time are with Peter’s family, as well as with his friends and colleagues throughout the Trust.
"Peter spent his working life as a dedicated public servant, joining the NHS after a long period working at HMRC. We are all grateful for his service. He will be missed."
In a personal message to all staff, Dr Bruno Holthof (Chief Executive Officer) and Professor Sir Jonathan Montgomery (Chair) said: "Any loss of a member of the OUH family affects us all. We are one team at OUH and we will support each other through these difficult times. We are very sorry to be bringing you such sad news."
Four NHS staff in Oxfordshire have now died whilst working during the pandemic.
Margaret Tapley, an 84-year-old nurse at Witney Community Hospital died last month after contracting coronavirus.
It's thought Oscar King and Elbert Rico, two hospital porters who worked at the JR Hospital, caught the virus too and also died in April.
