The Centers for Disease Control and Prevention (CDC) estimates that 1,178,350 Americans are living with HIV; of those, approximately 240,000 are unaware of their HIV-positive status. Increasing the number of persons who are aware of their status is a critical strategy for preventing HIV infections. As of 2008, over half a million African Americans are estimated to be infected with HIV, with 21.4% undiagnosed. To increase awareness of HIV status, CDC established the Expanded Testing Initiative (ETI), under which three programs have been launched.
