Demands to get protective equipment to NHS staff have intensified after the deaths of several more frontline workers in the coronavirus pandemic.
A healthcare worker in Cardiff, a plaster technician in Doncaster and two porters at a hospital in Oxford were among the latest victims to be identified.
Donna Campbell, who worked at the Velindre Cancer Centre in Cardiff, was described by "heartbroken" colleagues as a "beautiful, kind-hearted friend".
Two porters, named locally as Oscar King Jr and Elbert Rico, were described as "popular and hard-working" members of the team at the city's John Radcliffe hospital.
Both men were married to members of the nursing team at the hospital, the trust said.
Doncaster Royal Infirmary also confirmed the death of plaster technician Kevin Smith.
After the deaths of dozens of NHS workers, the Royal College of Nursing has said its members should refuse to treat patients as a "last resort" if they did not have adequate personal protective equipment (PPE).
Labour leader Sir Keir Starmer backed the advice and said ministers' ambitions on PPE supply "isn't being matched" by action.
Several nurses were among the other victims whose deaths were confirmed over the Easter weekend. Among them was mother-of-four Sara Trollope, who worked at Hillingdon Hospital and was described as "an example to every one of us" for her kindness and hard work.
