In February 2020, members of the Washington, DC Regional Planning Commission on Health and HIV (COHAH) participated in a half-day engagement session, brainstorming relevant ideas for each pillar of the federal Ending the HIV Epidemic initiative: Diagnose, Treat, Prevent, and Respond. COHAH was included in all levels of planning and provided feedback on engagement plans, as well as communities to engage. DC Health presented the Ending the HIV Epidemic initiative update to COHAH before beginning accelerated community engagement. COHAH staff members were also members of the internal DC Health 1906 planning work group, and the work group staff attended the COHAH committee meetings. The COHAH Community Engagement and Education Committee provided guidance and connected people living with HIV to DC Health community engagement efforts.
