Outcomes of a model for re-testing HIV-negative index contacts in Sedibeng, South Africa.

Background: Index contact testing is an HIV case-finding approach that elicits sexual or needle-sharing partners, as well as biological children, of people living with HIV (PLHIV) and offers them HIV testing services.

Objectives: We aim to describe the results of an innovative project in Sedibeng District that expanded index testing by retesting previously negative contacts and incorporating status-neutral testing.

Method: We used registers to identify people who previously tested HIV-negative through index testing from March 2019 to September 2021.
