Screening for HIV: Systematic review to update the 2005 U.S. Preventive Services Task Force recommendation
BACKGROUND: A 2005 U.S. Preventive Services Task Force (USPSTF) review found good evidence that HIV screening is accurate and that antiretroviral therapy (ART) for immunologically advanced disease is associated with...
Cost-effectiveness of counseling and testing to prevent sexual transmission of HIV in the United States
In this paper we review the cost-effectiveness of HIV counseling and testing in various settings and populations in preventing the sexual transmission of human immunodeficiency virus, and we discuss how...
Head-to-head comparison of accuracy of a rapid point-of-care HIV test with oral versus whole-blood specimens: A systematic review and meta-analysis
