While HIV research remains priority in Sub-Saharan Africa (SSA), most of the studies have traditionally been conducted in secure locations with little focus on internally displaced person (IDPs) and how they rely on locally available strategies for care and survival. Thus the aim of this study is to fill this gap by investigating the role of indigenous social relations (particularly, peer support) in the promotion of care among IDPs living with human immunodeficiency virus (HIV) in a conflict region known as Kabaré in the south Kivu province of Eastern Democratic Republic of the Congo.Through a qualitative study, we show that despite having some limitations (e.g. lacked practical avenues to monitor and treat HIV-related complications), peer-support was crucial in providing much needed empathetic social, economic, psychological, material, nutritional and emotional supportive services to HIV positive IDPs. Peer support was also useful in promoting adherence to antiretroviral treatment including provision of financial support that opened survival pathways in the face of conflict, weak health systems and poverty.
