A final inquiry report detailing what happened in the UK's infected blood scandal in the 1970s and 1980s will be published on Monday.
Around 3,000 people are believed to have died as a result of being infected with HIV and hepatitis from blood transfusions during what's seen as the deadliest scandal to afflict Britain's state-run National Health Service since its inception in 1948.
The inquiry report is expected to criticise pharmaceutical firms and medical workers, civil servants and politicians, though many have already died given the passage of time.
It's also set to pave the way to a huge compensation bill that the British government will be under pressure to rapidly pay.
“This whole scandal has blanketed my entire life,” said Jason Evans, who was 4 when his father died at the age of 31 in 1993 after contracting HIV and hepatitis from an infected blood plasma product.
“My dad knew he was dying and he took many home videos, which I’ve got and replayed over and over again growing up because that’s really all I had,” he added.
Evans was instrumental in the decision by then-Prime Minister Theresa May to establish the inquiry in 2017.
He said he just "couldn’t let it go". His hope is that on Monday, he and countless others, can.
What is the infected blood scandal?
Thousands of people who needed blood transfusions in the 1970s and 1980s were exposed to blood tainted with hepatitis and HIV.
Those with haemophilia, a condition affecting the blood’s ability to clot, became exposed to what was sold as a revolutionary new treatment derived from blood plasma.
In the UK, the NHS, which treats the vast majority of people, started using the new treatment, called Factor VIII, in the early 1970s.
It was more convenient when compared with an alternative treatment and was dubbed a wonder drug.
As demand overtook supply, health officials imported the drug from the US, where many plasma donations came from prisoners and drug users paid to donate blood, raising the risk of it being contaminated.
Factor VIII was made by mixing plasma from thousands of donations. In this pooling, one infected donor would compromise the whole batch.
The UK inquiry heard estimates that more than 30,000 people were infected from compromised blood or blood products via transfusions or Factor VIII.
The inquiry is expected to conclude that lessons from as early as the 1940s had been ignored.
