In the United States, over one million live with HIV, and 24 to 27 percent of these people are unaware of their HIV infection1. Additionally, CDC estimates that approximately 40,000 persons in the United States become infected with HIV each year,2 making HIV prevention a national health priority and tracking at-risk behaviors an essential part of developing successful prevention efforts.3
