How Many People Have HIV/AIDS?

A young girl sitting in a café is sending a text message about HIV/AIDS to her friendHIV/AIDS has been a global epidemic for more than 30 years. Most of today's youth have never known a world without it.

In 2011, an estimated 49,000 people were diagnosed with HIV and approximately 21 percent of them were aged 13-24, with the highest rate of new infections occurring among those aged 20-24. [**]

The Centers for Disease Control and Prevention (CDC) estimates that about 1 in 6 people in the United States who are infected with HIV do not even know it. [*]

Although blacks, or African Americans, made up only 12 percent of the population in the 46 states, they accounted for 46 percent of the new HIV diagnoses during 2010.
