Home testing and counselling to reduce HIV incidence in a generalised epidemic setting: a mathematical modelling analysis

Key Points

The aim is to evaluate how periodic home testing and counselling affects HIV incidence.
Mathematical model used to simulate scenarios of home HTC programs.
Focus on individuals with high HIV viral load.
Setting: KwaZulu-Natal, South Africa.
Periodic home HTC may significantly reduce HIV incidence.
Targeting those with high viral loads optimizes antiretroviral therapy expansion.
Mathematical results suggest potential for improved healthcare outcomes.

Abstract

Home HIV testing and counselling (HTC) achieves high levels of HIV testing and linkage to care. Periodic home HTC, particularly targeted to those with high HIV viral load, might facilitate expansion of antiretroviral therapy (ART) coverage. We used a mathematical model to assess the eff ect of periodic home HTC programmes on HIV incidence in KwaZulu-Natal, South Africa.
