Adolescents and Young People
Adolescents are defined as people between 10 and 19 years old, while young people are defined as those between 10 and 24 years old. There are 5 million youth living with HIV around the world. In addition, more than 30% of all new HIV infections globally are estimated to occur among youth ages 15 to 25 years.
Relevant Studies:

Cisgender Men Who Have Sex with Men
Rates of HIV infection are disproportionately high among cisgender men who have sex with men (MSM) in all regions of the world. This group is 19 times more likely to be living with HIV than the general population.
Relevant Studies:
HVTN 704/HPTN 085, HPTN 083, HPTN 083-02, HPTN 094, HPTN 096
Transgender Women
Transgender women are around 49 times more likely to be living with HIV than other adults of reproductive age with an estimated worldwide HIV prevalence of 19%. In some countries the HIV prevalence rate in transgender women is 80 times higher than of the general adult population.
In addition, transgender people have low rates of access to health and HIV services due to a range of issues including violence, legal barriers, stigma and discrimination.
