Donor funding for HIV programs, many of which rely heavily on donor funding, has flattened out in recent years, limiting the ability of HIV programs worldwide to achieve universal access and sustain current progress. As an infectious and chronic disease, HIV requires sustained resources for prevention and treatment. Due to the recent global recession and donor priorities shifting away from HIV, donors are demanding greater counterpart participation, which is increasingly affordable for many recipient countries. The above trends require national health sector policymakers to expand their fiscal space to address the financial sustainability of the HIV programs as their donor funding is set to decline. This study examines four non-donor funding mechanisms for HIV programs.
