Men who have sex with men (MSM) who cured from hepatitis C virus (HCV) infection are at substantial risk of HCV reinfection. In this study, the investigators aim to evaluate the effectiveness of an online behavioural intervention, a home-based testing intervention and a combination of both on risk behaviour, and ultimately preventing HCV reinfection and onward spread of HCV.
Inclusion Criteria: * Informed consent documented by signature. * Male individual aged 18 years or older. * History of a cured or spontaneously cleared HCV infection (positive HCV RNA test in the past and/or positive anti-HCV IgG). * Self-reported MSM who are either (i) HIV-positive seeking care at an HIV treatment center or (ii) HIV-negative and seeking care at an STI/PrEP/sexual health center. * Sufficient understanding of Dutch or English. * Have internet access and an e-mail address. Exclusion Criteria: * Acute or chronic HCV infection at time of enrolment. * Under HCV treatment at time of enrolment. * Unlikely, in the opinion of the clinician, to comply with the study procedures. * Currently participating in an intervention study that offers extra HCV testing and/or a behavioural intervention targeting risk behaviour. * Investigators or otherwise dependent persons.
