I will be the first to admit I never really thought about philanthropy when I was young.  I didn't even know malaria existed until I was in my late teens.  It was inspiring for me to read this New York Times piece about children who have gotten involved in the fight against malaria, one of whom has raised $43,000 dollars! Children understand the damage malaria can do and the moral imperative of doing something in response.  A long lasting insecticide treated mosquito net is a beautiful thing indeed.  If a family receives one, retains it, and sleeps under it properly, it will have a major protective effect.  At ten dollars (or under) a net, it is an excellent investment, whether in Sub-Saharan Africa or in Haiti which also is malaria endemic.   The full article is copied below.  

Friday was World Malaria Day 2008.  Global health depends on controlling this global disease.  It is the leading cause of death in African children and a major health concern in Haiti.  It overwhelms fragile health care systems and hurts economies - the annual economic loss in Africa due to malaria is estimated to be $12 billion (1.3% loss in GDP.)   Yet, we know how to prevent it and how to treat it.  There has been tremendous progress made in the past year, so much so that the international community increasingly agrees that we should begin working toward eradication - in other words, a world without malaria.  It would be a better world indeed.
