Early detection is also important for diagnosing and assessing the prognosis for people with HIV and hepatitis C and for preventing transmission of disease. Incorporating testing based on risk (for example as part of an Adult Health Check in ACCHS and other primary healthcare facilities) is recommended as an important preventative measure to reduce transmission of BBVs. This applies also in juvenile justice and adult custodial settings. Increasing the ability of ACCHS to provide tertiary care through visiting specialists has improved the retention rate of clients accessing treatment for viral hepatitis in at least one ACCHS in Australia since 2006. This model should be assessed for further implementation in other settings.

The diagnostic event shapes how people with HIV and hepatitis C understand their infection. It is essential that diagnosis be handled sensitively and that everyone being tested receives information about hepatitis C treatment options and the support services available. The national HIV and hepatitis C testing policies provide a framework for these activities.
