Global efforts to control and eliminate malaria have saved an estimated 3.3 million lives since 2000, reducing malaria mortality by half in sub-Saharan Africa, according to the World Malaria Report 2013 published by the World Health Organization (WHO). Nearly 70% of these lives saved were in the 10 countries with the highest malaria burden, and among children under 5 years of age – the group most affected by the disease.
