The World Swim Against Malaria was the brainchild of Rob Mather, a London-based strategy consultant. Mather had earlier organized a swim to raise money for a two-year-old girl who was badly burned in a house fire. Held in December 2003, the "Swim for Terri" started as a three-person fundraiser and grew to include 10,000 swimmers in 73 countries. AMF was founded in 2004 in London. It is rated as a highly cost-effective charity by
GiveWell. AMF was chosen as one of GiveWell's two highest-recommended charities (along with the
Schistosomiasis Control Initiative) in 2011 and has continued to be recommended by GiveWell since then. GiveWell estimated in 2023 that AMF's bed net program costs on average per life saved. == Operations ==
