Haakenstad A, et al. - Domestic malaria spending by source was determined in 106 countries that were malaria-endemic in 2000–16 or became malaria-free after 2000. Data revealed spending of US$4·3 billion on malaria worldwide in 2016; researchers observed an 8·5% per year increase over spending in 2000. Since 2000, 3·8% (3·3–4·2) per year increase in OOP spending was noted, amounting to $556 million (487–634) or 13·0% (11·6–14·5) of all malaria spending in 2016. Governments spending of $1·2 billion (1·1–1·3) or 28·2% (27·1–29·3) of all malaria spending was reported in 2016, increasing 4·0% annually since 2000. Depending on whether countries were in the malaria control or elimination stage, variation in the source of malaria spending was observed. Tracking global malaria spending is valuable for assessing how far the world is from reaching the malaria funding target of $6·6 billion annually by 2020. They identified mobilizing additional government resources for malaria as challenging in view of the fact that most countries with a high burden of malaria are low income or lower-middle income.
