Despite major progress in South Africa’s HIV response, Key Populations (KPs) and Vulnerable Groups (VGs)—including female sex workers, men who have sex withmen, people who inject drugs, and adolescent girls and young women—remain disproportionately affected. The barriers they face are rooted not in a lack of medication, but in powerful structural drivers: punitive laws, persistent social stigma, gender inequality, discrimination, violence, and health services that are often unwelcoming or unsafe. These challenges are compounded by gaps in basic health worker training, which can lead to secondary stigma within healthcare settings and discourage engagement with HIV testing, prevention (such as PrEP), and treatment (ART).
