My wife got malaria all the time in Nigeria, it was like a really bad cold or a flu in America. You get over it and move on. Only if your immune system is already compromised in some other way like old age or whatever malaria isn't really that big a deal among those who were strong and healthy before getting it. Instead of trying to stop malaria, focus on how they can get food. If they're well fed and strong/healthy, the malaria won't kill 'em just like it didn't kill my wife or any of her 5 siblings, or her university classmates, or my parents, or their siblings, etc. Now, there are those in Africa who don't have plenty to eat and/or have stressful daily lives that prevent getting a couple of days of rest. That is what allows malaria to kill so many. Just like the flu in America would kill a whole lot more often if there was a lack of food or inability to get consecutive days of rest.
