In 2017, approximately 47% of new HIV infections globally were among key populations and their sexual partners.
Members of key populations are at a significantly higher risk of contracting HIV. The available data suggest that the risk of HIV acquisition among gay men and other men who have sex with men was 28 times higher in 2017 than it was among heterosexual men. Similarly, the risk of acquiring HIV for people who inject drugs was 22 times higher than for people who do not inject drugs, 13 times higher for female sex workers than adult women aged 15–49 years and 13 times higher for transgender women than adults aged 15–49 years.
