Number of yearly post-neonatal child malaria deaths prevented by ITNs, according to different scale-up scenarios 2011-2015. Continuing current trend was calculated using the slope between the most recent survey estimate and the earliest survey estimate (solid blue line). Achieving 100% coverage by 2015 assumes linear ITN coverage increases to 100% from estimated coverage in 2010 (dotted purple line). Maintaining coverage assumes estimated coverage in 2010 continues through 2015 (dashed orange line). Ceased funding was calculated assuming that ITNs last three years and have a net discard rate of 4% each year  (dashed red line).
