The increase in global financial support from 2005 onwards has had a significant impact on malaria burden but has plateaued in recent years. To achieve further reductions in malaria burden alongside meeting the malaria elimination targets set out in the WHO Global Technical Strategy, the limited financial resources available must be allocated and spent efficiently. In this talk I will discuss recent work combining data on domestic and international financing with a malaria transmission model to estimate the additional gains that could be made if resources are efficiently allocated and targeted. I will also discuss some of the challenges in doing so.
