Against Malaria Foundation

Preventing deaths from malaria in sub-Saharan Africa

Malaria is a major problem in sub-Saharan Africa. Over 1 million people – mostly children – die each year. Insecticide-treated bed nets prevent deaths and many other non-fatal cases of malaria and are relatively inexpensive – about $5 per net (for more, see our full report on bed nets). We believe that AMF effectively expands access to bed nets.

Deworm the World Initiative (led by Evidence Action)

Treating children for parasite infections in developing countries

The Deworm the World Initiative (Deworm the World), led by Evidence Action, supports programs that treat children for parasitic worm infections that cause short-term symptoms such as anemia, and may cause longer-term developmental problems. These worms are extremely inexpensive to treat (for more, see our full report on deworming). Deworm the World focuses on advocacy and technical assistance to governments providing deworming, and we believe that it cost-effectively increases the number of children receiving deworming treatment.

GiveDirectly

Transferring cash grants to poor households in Kenya

Directly transferring money to the very poor allows recipients to purchase that which they believe will help them most. Strong evidence indicates that cash transfers lead recipients to spend more on their basic needs (such as food) and may allow recipients to make investments with very high returns, with no evidence of large increases in spending on items like alcohol or tobacco (for more, see our full report on cash transfers). We believe that GiveDirectly effectively distributes cash to extremely low-income individuals.

Schistosomiasis Control Initiative (SCI)

Treating children for parasite infections in sub-Saharan Africa


In sub-Saharan Africa, a large proportion of people, often children, are infected with parasitic worms that cause short-term symptoms such as anemia, and may cause longer-term developmental problems. These worms are extremely inexpensive to treat (for more, see our full report on deworming). We believe that SCI effectively expands access to deworming treatment.

The Global Alliance for Improved Nutrition (GAIN) – Universal Salt Iodization (USI) program

Aiding salt iodization programs in developing countries

Iodine deficiency, which remains common in the developing world, harms cognitive development. Fortifying salt with iodine successfully alleviates this problem (for more, see our full report on salt iodization). GAIN’s USI activities vary considerably across countries and include advocacy, technical assistance, supplying equipment, training government officials and salt producers, and monitoring, among others.

Iodine Global Network (IGN), formerly ICCIDD

Aiding salt iodization programs in developing countries

Iodine deficiency, which remains common in the developing world, harms cognitive development. Fortifying salt with iodine successfully alleviates this problem (for more, see our full report on salt iodization). IGN aims to reduce iodine deficiency globally by advocating for national salt iodization programs, tracking progress on iodization, and providing global and country-specific guidance on related programmatic and scientific issues.
