Of those at risk are men who have sex with men (MSM) but who do not necessarily define themselves as gay. When nursing or medical staff assume that all men are heterosexual, it puts MSM at risk of being misdiagnosed and mistreated for various infections and viruses, including HIV.Anova Health has launched an initiative called Health4Men, which trains medical staff to ensure prejudice-free and responsible healthcare is provided for this at-risk and often stigmatised social group.This is the story of their ambassador and nurse trainer, and the challenges they have both faced in the pursuit of HIV reduction for MSM in South Africa.
