Effectiveness and cost-effectiveness of nationwide campaigns for awareness and case finding of hepatitis C targeted at people who inject drugs and the general population in the Netherlands.

Background: Hepatitis C virus infection (HCV) is a serious, but underdiagnosed disease that can generally be treated successfully. Therefore, a nationwide HCV awareness campaign was implemented in the Netherlands targeting people who inject drugs (PWID) in addiction care ('PWID intervention') and high-risk groups in the general population ('public intervention'). The objective of this study is to assess the effectiveness and cost-effectiveness of the interventions used in this campaign.
