Haemophilia is a rare, hereditary bleeding disorder. Clotting factor concentrates were a revolutionary treatment which changed the life of people with haemophilia. However, early generation of clotting factor concentrates, without viral inactivation procedures in the manufacturing process, led to an increased risk of transmission of blood-borne viral infections, mainly due to hepatitis C virus and human immunodeficiency virus. As only 20% of HCV-infected patients clear the infection naturally, chronic HCV infection constitutes a serious health problem and a major cause of chronic liver disease in this group of patients. Fortunately, the use of viral inactivation procedures in the plasma-derived factor concentrates manufacturing process and the availability of alternative treatment options, led to a significant reduction of transfusion-associated viral infections. The advent of multiple, orally administrated, highly effective direct-acting antivirals (DAAs) is changing the natural history of HCV infection in patients with haemophilia as these drugs have an excellent safety profile and achieve very high sustained virological response rates, similar to the general population. Eradication of HCV-infection in patients with haemophilia is feasible via micro-elimination projects.
