Sero-epidemiology of human immunodeficiency virus (HIV) in Plateau State, Nigeria.

Introduction: Previous sentinel surveys of HIV in Nigeria studied pregnant women attending antenatal care, thereby omitting other important high-risk groups. We therefore investigated the prevalence of HIV/AIDS in low- and high-risk populations in the state of Plateau, Nigeria.

Methodology: Blood samples were collected by venepuncture from 5,021 adults aged ≥ 15 years between August and October 2008.
