The Australian Needle and Syringe Program Survey (ANSPS) provides serial point prevalence estimates of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) antibodies and sexual and injecting risk behaviour among people who inject drugs (PWID) in Australia. Conducted annually over a one-two week period in October, all clients attending participating needle and syringe program (NSP) services are invited to complete a brief, anonymous questionnaire and to provide a capillary blood sample for HIV and HCV antibody testing.
This report presents national and state/territory data for the period 2011 to 2015.
