Malaria is one of the biggest killers of children on the planet, and Cambodia has made phenomenal progress fighting it over the past decade or so. Deploying an army of more than 3,000 village malaria workers who administer tests, give out medicine, and distribute bednets, they have reduced malaria from about 130,000 cases in 2000 to about 2,000 in 2012. Now the goal is to build on this progress by wiping out malaria entirely within Cambodia.
