What this is

Malaria mortality is heavily concentrated in Sub-Saharan Africa and among children under five. Progress stalled in the 2020s as insecticide resistance, drug resistance, funding gaps and climate-driven range expansion offset gains from bed nets and new vaccines. It is one of the most cost-effective mortality reductions available anywhere, which makes the persistent toll a resource-allocation failure as much as a biological one.
