Hepatitis C: risk factors
In Scotland, following the introduction of heat treatment of blood factor in 1986, and the screening of blood donors in 1991, persons have not been at risk of acquiring the hepatitis C virus (HCV) through the receipt of blood / blood factor. In resource rich countries, HCV is mainly transmitted among injecting drug users who share injecting equipment though, occasionally, infection is spread through sexual intercourse or from mother to child during pregnancy or at the time of birth. HCV, relatively rarely is acquired through the use of un-sterile sharp equipment in healthcare and non-healthcare (e.g. tattoo parlour) settings. In resource poor countries, HCV is mainly transmitted through the receipt of infected blood / blood products and through the re-use of un-sterile needles and syringes for healthcare purposes.
