Blood borne viral and sexually transmissible infections in Aboriginal and Torres Strait Islander peoples: Annual surveillance report 2025

This report provides information on the occurrence of blood borne viruses (BBVs) and sexually transmissible infections (STIs) among Aboriginal and Torres Strait Islander peoples in Australia. The report is published for the purposes of stimulating and supporting discussion on ways to minimise the risk of transmission of these infections as well as the personal and social impacts within Aboriginal and Torres Strait Islander communities. The report is produced for use by a wide range of health service providers and consumers, and particularly Aboriginal and Torres Strait Islander health services and communities.
