Background: Biomedical successes have transformed Human Immunodeficiency Virus (HIV) from a life-limiting disease to a chronic, manageable condition. With this shift, the onus has turned to people living with HIV (PLHIV) to self-manage. HIV self-management is frequently framed as the individualistic pursuit of health behaviours with success measured in terms of antiretroviral (ART) uptake and adherence. Less attention has been paid to the social contexts in which self-management occurs, and the social networks that support self-management. Social networks are an important resource for people living with chronic conditions. Alongside the provision of support for health behaviours, social networks can promote a sense of value, belonging and solidarity. Yet little is known of the social networks that support recently diagnosed PLHIV, their experiences of seeking and mobilising network support, and how these experiences are shaped by the pervasive stigma that continues to surround HIV.
