HIV self- and partner-testing as democratization of medical technology to aid stigmatized populations

This project seeks to establish the basis for the promotion of HIV self- and partner testing through non-governmental organizations as a way to contribute to the democratization of a biomedical technology to prevent HIV transmission. The goal is to demonstrate that unrestricted access to HIV-self testing can simplify and popularize its use, bring power and self-determination to people, and bypass HIV-stigma. The project examines how availability of HIV self-testing can be an innovating way to provide humanitarian aid to stigmatized populations that presently fear accessing HIV prevention and care.

The project will be carried out in collaboration with INSERM, AIDES, and the ANRS public health “Action coordonnée.” Its aims are to explore ways to educate, motivate and strengthen the capacity of NGOs involved in HIV prevention to promote self-testing and partner testing. Furthermore, focusing on men who have sex with men and transgender people, the project also aims to sensitize them on the use of self- and partner-testing and to facilitate their access to testing before each potentially infectious sexual contact so as to help these populations to take informed decisions and minimize the risk of HIV transmission.
