More than 30,000 people in the UK were infected with HIV and Hepatitis C after being given contaminated blood products in the 1970s and 1980s.
A public inquiry into what has been called the biggest treatment disaster in NHS history will announce its findings on Monday.
Victims are campaigning for compensation.
Who was given infected blood and how many died?
Two main groups of NHS patients were affected.
Firstly, haemophiliacs – and those with similar disorders – who have a rare genetic condition which means their blood does not clot properly, external.
People with haemophilia A have a shortage of a clotting agent called Factor VIII, while people with haemophilia B don’t have enough Factor IX.
In the 1970s, a new treatment using donated human blood plasma was developed to replace these clotting agents.
But whole batches were contaminated with deadly viruses.
After being given the infected treatments, about 1,250 people in the UK with bleeding disorders developed both HIV and hepatitis C, including 380 children.
Around two-thirds later died of Aids-related illnesses. Some unintentionally gave HIV to their partners.
Another 2,400 to 5,000 people developed Hepatitis C on its own, which can cause cirrhosis and liver cancer.
It is difficult to know the exact number of people infected with Hepatitis C, partly because it can take decades for symptoms to appear.
A second group of patients were given contaminated blood transfusions after childbirth, surgery or other medical treatment between 1970 and 1991.
The inquiry estimates between 80 and 100 were infected with HIV, and about 27,000 with Hepatitis C.
In total, it’s thought about 2,900 people have died.

Why did the infected blood scandal happen?
In the 1970s, the UK was struggling to meet the demand for blood-clotting treatments, so imported supplies from the US.
But much of the blood was bought from high-risk donors such as prison inmates and drug-users.
Factor VIII was made by pooling plasma from tens of thousands of donors.
If just one was carrying a virus, the entire batch could be contaminated.
UK blood donations were not routinely screened for hepatitis C until 1991, 18 months after the virus was first identified.
What did authorities know about infected blood?
By the mid-1970s, there were repeated warnings that imported US Factor VIII carried a greater risk of infection.
But attempts to make the UK more self-sufficient in blood products failed, so the NHS continued using foreign supplies.
Campaigners say haemophiliacs could have been offered an alternative treatment called Cryoprecipitate. This was much harder to administer, but was made from the blood plasma of a single donor, lowering the infection risk.
BBC News has also uncovered evidence children were infected with hepatitis C and HIV after being placed on clinical trials of new treatments – often, without their family’s consent.
As late as November 1983, the government insisted there was no “conclusive proof” that HIV could be transmitted in blood, a line robustly defended by former health minister Ken Clarke when he appeared before the inquiry.
By the end of 1985, all Factor VIII products were heat-treated to kill the HIV virus.
When was the infected blood inquiry set up?
The UK-wide infected blood inquiry was announced in 2017, after years of campaigning by victims.
It was led by former judge Sir Brian Langstaff, and took evidence between 2019 and 2023.
The inquiry will publish its final report on 20 May.
It had been expected in autumn 2023, but Sir Brian said more time was needed to prepare “a report of this gravity”.
Exact numbers are difficult to establish, but the Haemophilia Society believes 650 people infected with contaminated blood products, or their bereaved partners, have died since the inquiry was announced.
Who gave evidence to the inquiry?
One of the first to take the stand was Derek Martindale, who has haemophilia. He was diagnosed with HIV and given a year to live in 1985, aged 23. He survived but his brother – who was also infected with HIV – did not.
The inquiry also heard harrowing testimony from former pupils at Treloar’s, a specialist boarding school in Hampshire, where dozens of young haemophiliacs were infected with HIV.
Specialist haemophilia doctors working at the time also gave evidence, external.
As well as Lord Clarke, the inquiry heard from former and current ministers in all four UK nations, including Prime Minister Rishi Sunak and Chancellor Jeremy Hunt.
Will infected blood scandal victims get compensation?
Those infected have received annual financial support from the government. However, a final compensation deal has not been agreed.
In late 2022, following advice from the inquiry, the government made interim payments of £100,000 each to around 4,000 surviving victims and some bereaved partners.
In April 2023, Sir Brian said interim compensation should also be offered to the children and parents of those infected.
He also recommended a final compensation scheme be set up.
The total cost is likely to run into billions.
The government has said it accepts the case for compensation but it would be “inappropriate” to respond before the inquiry’s full report.
In April 2024, ministers agreed to support a Labour amendment to the Victims and Prisoners Bill. It means a final compensation scheme must be set up within three months of the legislation becoming law.
What happened in other countries affected by infected blood?
Many other countries were affected by the same scandal, although some – including Finland – used older treatments until much later rather than switch to Factor VIII, which minimised HIV infections, external.
In the US, companies that supplied infected products have paid out millions in out-of-court settlements.
Politicians and drug companies have been convicted of negligence countries including France and Japan.
In his evidence to the inquiry, former health secretary Andy Burnham suggested there may be grounds for charges of corporate manslaughter, external in the UK.
