The Against Malaria Foundation (AMF) fights malaria by distributing insecticide-treated mosquito nets. AMF has been rated a top charity by Givewell, Giving What We Can, and The Life You Can Save. Delivering a net costs just $5.31. For every $3500 we raise, we can prevent one person from dying from malaria. For comparison, the UK’s National Health Service will spend up to £20,000 (over $30,000) for a single year of healthy life saved! Malaria killed around 438,000 people in 2015. Seventy percent of these deaths are of children under five years old, making malaria one of the leading causes of child mortality in Africa. Even when non-fatal, malaria can damage children’s cognitive development. Lower malaria rates help more children stay in school and more adults continue working, which stimulates developing economies. For every $1 spent fighting malaria, Africa’s GDP improves by at least $6.75–and by some estimates much more. Well-designed action against malaria has been shown to be hugely successful: since 2000, mortality rates have fallen by 47 percent globally and by 54 percent in the WHO African Region.
