HIV activist Boubacar Camara tests a man for HIV at the Médecins Sans Frontiers (MSF) mobile clinic in the neighbourhood of Tombolia, Conakry, Guinea on March 18, 2016.

In Guinea, only one in four people living with HIV are on life-saving antiretroviral treatment. Lack of voluntary HIV testing, estimated at only 5% from the latest study dating from 2012, hampers the necessary increase of people on ART.
