Malaria continues to be one of the world's most destructive and widespread diseases, killing around 500,000 people each year, almost all of them in sub-Saharan Africa.

On World Malaria Day we hear how it continues to cripple communities and speak to one Kenyan woman who lost a child to the disease. Ethiopia's former health minister, Dr Kesete Admasu, explains how outbreaks can have far-reaching economic consequences, depriving farms and other businesses of workers at vital times. He also describes his current work at Roll Back Malaria, a foundation aiming to tackle the disease through genetically engineered mosquitoes and new vaccines.

Plus, Kenyan infectious disease specialist Dr Faith Osier tells us about another malaria vaccine she's working on, and we hear about the smartphone that could alert people when the breeds of mosquitoes that carry the disease are nearby.
