Key Points
  • Youths aged 13-24 years account for 7% of the estimated 1.1 million persons living with human immunodeficiency virus (HIV) infection in the United States.
  • In 2010, 26% of estimated new HIV infections were among youths: 57% among blacks/African Americans, 20% among Hispanic/Latinos, and 20% among whites.
  • Nearly 75% of the 12,200 new HIV infections among youths were attributable to male-to-male sexual contact.
  • Only a low percentage of youths have been tested for HIV, and 60% of youths with HIV are unaware of their infection.
  • Young males who have sex with males are at increased risk for HIV because of high rates of HIV in potential sex partners, and they are more likely to engage in HIV-related risk behaviors (e.g., unprotected sexual intercourse and injection drug use) than other male or female high school students.
