The New York Times reports on a study published last week in PLOS ONE showing the rapid deployment of community health workers in Yirimadjo, Mali, helped create “a 90 percent drop in deaths among young children from 2008 to 2011.” Lead author Ari Johnson of the University of California San Francisco School of Medicine “argued that the additional expenditure amounted to only $8 per resident per year,” the New York Times notes, adding, “When added to the $45 per person Mali normally spends on health, he said, that is ‘well within the range’ of normal health spending in Africa — less than is spent, for example, in Rwanda and Senegal” (McNeil, 12/16).
