The Centers for Disease Control and Prevention (CDC) estimates more than 1.1 million people in
the United States are living with human immunodeficiency virus (HIV) infection, including 18% who
remain undiagnosed.1 In July 2010, the Office of National
AIDS Policy issued the first National HIV/AIDS Strategy for the United States, with a short-term
goal of reducing the number of individuals with undiagnosed HIV infection to 10% by 2015 and a more
general goal of creating an AIDS-free generation.2 Screening
and testing for HIV infection is at the forefront of efforts to achieve these goals, and in 2013 the
US Preventive Services Task Force (USPSTF) supported a broader HIV screening approach by changing
its recommendation for routine HIV screening from grade C to grade A.3
