HPTN Study Populations

The HPTN works with five distinct study populations: adolescents and young people; cisgender men who have sex with men (MSM); cisgender women; people who inject drugs; and transgender women who have sex with men.

Adolescents and Young People

Adolescents and young peopleAdolescents 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.

Cisgender Men Who Have Sex with men

MSMRates 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.

Cisgender Women

About 17.4 million adults living with HIV are cisgender women.

People Who Inject Drugs

People who inject drugs account for approximately 10% of HIV infections globally and 30% of those outside of Africa.

Transgender Women

Transgender pride flagTransgender 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.
