A public inquiry has begun hearing from former students after more than 120 pupils at a school for disabled children were caught up in what has been called the worst treatment disaster in NHS history.

From 1974 to 1987, those children were offered treatment for haemophilia at Treloar's College.

At least 72 died after being given a drug contaminated with HIV and viral hepatitis.

Lord Mayor's Treloar's College was a boarding school for physically disabled children with a specialist NHS haemophilia centre on site, run by a dedicated medical team.

By the mid 1970s, a new treatment for haemophilia, known as factor VIII/IX, became available for the first time.

Like dozens of other boys at the school, he was given factor VIII to help control his bleeding.

In 1985 he was taken into a small office with a group of boys to be told he had tested positive for HIV - then a newly discovered virus with no known treatment and a short life expectancy.

Ade's two older brothers died after treatment with factor VIII - Jason from Aids in 1997 and Gary from health problems linked to hepatitis C in 2015.

It's hoped the public inquiry will be able to answer questions about what happened at Treloar's and the NHS haemophiliac centre run from the site.

Families want to know why they were not told about the potential risks of Factor VIII earlier and why it took many years until the drug was heat treated to kill viruses and other contaminants.

"What happened at the school comes back to haunt us every day," said Stephen Nicholls, a former pupil who was infected with hepatitis C after his treatment.

"We will never forget the Treloar's story and those memories of what happened here.".

People with the condition produce lower amounts of the essential blood-clotting protein known as factor VIII and IX?

The haemophilia centre on the site was run by NHS doctors and nurses and not staff directly employed by the school, which still cares for physically disabled children today.

"Although no-one has at any point suggested that Treloar's was at fault, it is a tragic part of our past," the school said in a statement.
