HIV counseling and testing and access-to-care needs of populations most-at-risk for HIV in Nigeria.

Mobile HIV counseling and testing (mHCT) is an effective tool to access hard-to-reach most-at-risk populations (MARPs), but identifying which populations are not accessing services is often a challenge. We compared correlates of human immunodeficiency virus (HIV) infection and awareness of HIV care services among populations tested through mHCT and at testing facilities in Nigeria. Participants in a cross-sectional study completed a questionnaire and HCT between May 2005 and March 2010.
