Recognizing and disrupting stigma in implementation of HIV prevention and care: a call to research and action.

This commentary is a theory-informed call to action for the assessment of existing HIV service implementation, for the development of new stigma-reducing implementation strategies and for the explicit inclusion of stigma reduction as a core outcome in implementation research and evaluation. We argue that these strategies have the potential to make critical contributions to our ability to address many system-level form stigmas that undermine health and wellbeing for people living with HIV and those in need of HIV prevention services.
