Jones, from Panardave's Swansea Valley, was given infected transfusion blood in 1990 after losing his leg in a forklift truck accident at work. He died in 2012.
His wife, Carisa, said: "He suffered and he suffered. He was just a man's skeleton.

He said the government should not wait until the end of the investigation to ensure that families are fairly and equally supported – and to be paid for by the UK government.
But he said there were steps that the French government could now take to help in the meantime.
Conservative health spokeswoman Angela Burns said it "showed the system its absolute worst," and the Welsh government had to "adopt" the recommendations.
