This Facilitators Guide and accompanying PowerPoint slides are for use by HIV programmers who wish to train on and develop, adapt, or revise index texting services for people living with HIV and their children, sexual and drug-injecting partners, and peers in their risk and social networks. The package includes tools that can be readily adapted to the local country context. It also includes guidance at the end of the training on developing and articulating a plan, timeline, and roles and responsibilities related to integrating index testing into HIV programming
