Abstract

Today's HIV/AIDS Epidemic 1 TODAY’S HIV/AIDS EPIDEMIC CDC estimates that 1.1 million people in the United States are living with HIV – and nearly one in six of those are not aware that they are infected.1 Approximately 50,000 people become newly infected each year.2 In addition to recognized risk behaviors, a range of social and economic factors places some Americans at increased risk for HIV infection. Prevention efforts have helped keep the rate of new infections stable in recent years, but continued growth in the number of people living with HIV ultimately may lead to more new infections if prevention, care, and treatment efforts are not targeted to those at greatest risk. The Scope and Impact of HIV in the United States New infections and overall burden: Since the height of the epidemic in the mid-1980s, the annual number of new HIV infections in the United States has been reduced by more than two-thirds, from roughly 130,000 to approxi- mately 50,000 annually.2 As a result of treatment advances since the late 1990s, the number of people living with HIV (HIV prevalence) has increased dramatically.1 Yet, despite increasing HIV prevalence and more opportunities for HIV transmission, the number of new infections has been relatively stable since the mid-1990s.2 HIV Prevalence and New Infections, 1980-2010 Heavily affected subgroups: By transmission category, the largest number of new HIV infections cur- rently occurs among men who have sex with men (MSM) of all races and ethnicities, followed by African American heterosexual women. By race/ ethnicity overall, African Americans are the most heavily affected, followed by Latinos.2 U.S. Subpopulations with the Largest Numbers of Estimated New HIV Infections, 2010 11,200 10,600 6,700 5,300 2,700 1,300 1,200 1,100 850 780 0 4,000 2,000 6,000 8,000 10,000 12,000 Wh ite M SM Bla ck MS M Bla ck Het ero sex ual Wo me n His pan ic M SM Bla ck Het ero
