The Centers for Disease Control and Prevention has released its latest estimates on the number of new HIV infections in the United States:
HIV remains a serious health problem, with an estimated 47,500 people becoming newly infected with the virus in the United States in 2010. Youth make up 7% of the more than 1 million people in the US living with HIV. About 12,000 youth were infected with HIV in 2010. The greatest number of infections occurred among gay and bisexual youth. Nearly half of all new infections among youth occur in African American males.
