Organizers say several thousand people are expected to turn out Sunday in Washington for a march ahead of an international AIDS conference that’s getting under way in the city.

The “Keep the Promise” march, which is set to begin at 2 p.m. Eastern time at the Washington Monument, is being organized by the Los Angeles-based AIDS Healthcare Foundation. Organizers say their aim is to remind world leaders and policymakers that AIDS remains a threat to global health.

They’re calling for funding of programs that fight AIDS and they want lower prices on AIDS drugs. They also are pressing for universal access to condoms and increased rapid HIV testing.

The 2012 International AIDS Conference opens on Sunday evening and runs through July 27.
