An estimated—we heard—12,000 to 14,000 people are currently living with hepatitis C in Wales, around half undiagnosed. It’s one of three main causes of liver disease and the only one of the five big killers in Wales and England where deaths are rising. It therefore represents a significant public health challenge. As I said in January’s debate on the contamination of blood, in the 1970s and 1980s, a large proportion of blood products supplied to patients by the NHS was contaminated with HIV or hepatitis C. Around 4,670 patients with haemophilia were infected and over 2,000 have since died in the UK, including 70 in Wales, from the effects of these viruses. However, evidentially, hepatitis C primarily affects people from particular groups, such as injecting drug users, homeless people, gay and bisexual men, and migrant populations from high-prevalence regions.
