HIV self-testing: A review and analysis to guide HIV prevention policy.

HIV self-testing is a relatively new approach to HIV testing that, with increasing licensure in many countries, is an impending intervention. Considering such current or near-future implementation, it is important for HIV prevention policymakers to reflect on if and how to incorporate HIV self-testing. In this paper, using the Impact Fraction Model and the Anderson-May equation, I discuss how HIV self-testing should be an efficacious prevention approach when targeted appropriately. I then review the potential impacts of self-testing on HIV surveillance and discuss possible ethical concerns about such testing. The outcome of this analysis is that, while some issues may arise related to surveillance, and while some ethical concerns can be raised, no empirical evidence substantiates either, suggesting that HIV self-testing is an important strategy if it can be focused on and used by the persons most affected by HIV.
