"CDC estimates that more than 1.1 million people in the United States (US) are living with HIV infection. Nearly one in five (18.1%) of those people are unaware of their infection. Despite increases in the total number of people in the US living with HIV infection in recent years (due to better testing and treatment options), the annual number of new HIV infections has remained relatively stable. However, new infections continue at far too high a level, with approximately 50,000 Americans becoming infected with HIV each year.
"In 2010, an estimated 47,129 people were diagnosed with HIV infection in the 46 states with confidential name-based HIV infection reporting since at least January 2007. In that same year, an estimated 33,015 people throughout the U.S. were diagnosed with AIDS. Since the epidemic began, an estimated 1,129,127 people in the U.S. have been diagnosed with AIDS.
"An estimated 17,774 people with AIDS died in 2009, and nearly 619,400 people with AIDS in the U.S. have died since the epidemic began."
