Training lay people to conduct HIV testing can be an effective approach to reach high-risk populations and prevent the spread of the infection throughout the world, a study has found. Lay providers can serve as a critical addition to efforts to help achieve the United Nations' global HIV targets by 2020 and help to cover the "last mile" of HIV services to at-risk populations.

Stigma related to human immunodeficiency virus ( HIV ) impairs cognition in men living with the condition, finds a study.

This study is the first to draw a direct connection between stigma and cognitive performance in people with HIV. The mechanisms through which stigma affects cognition are unclear, but might range from the impact of chronic stress on the brain, t...
