Over the last two decades, HIV and AIDS have been framed as a "global problem". In the process, transnational advocacy networks have emerged as important actors, and particular places are recognised as key nodes in global HIV and AIDS governance. Using the example of London, UK, this paper examines how these networks are involved in local articulations of global governance and reveals that 'global' processes are inflected by the locations through which networks are routed. The example suggests the need for further analysis of the geographies through which HIV and AIDS is reconfiguring power relations at a variety of spatial scales.
