The AIDS Support and Technical Assistance Resources Contract (AIDSTAR) establishes a mechanism to make technical assistance and implementation support available to USAID's Office of HIV/AIDS (OHA) in all countries where the President's Emergency Plan for AIDS Relief is providing HIV/AIDS assistance, including both focus and non-focus countries. On request, AIDSTAR supports USG operating units, including USG country teams, USAID/Washington (USAID/W) Bureaus and other USG agencies, in implementing the President's Emergency Plan and contributing to achievement of Emergency Plan goals in two different sectors: 1. HIV/AIDS Prevention, Care and Treatment; and 2. HIV/AIDS Institutional Capacity Building. AIDSTAR provides the Government with cost-effective access to technical expertise and implementation support to meet evolving HIV/AIDS needs.
