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. Approximately 50,000 people become newly infected each year. 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.
