How malaria deaths were halved since 2000

The number of people dying from malaria across the world has halved since the year 2000. The World Health Organisation says that the positive figures are thanks to global as well as regional efforts and a three-fold increase in funding.

Between 2001 and 2013, 4.3 million deaths were averted, 3.9 million of which were children under the age of five in sub-Saharan Africa. The number of people infected has also fallen by a quarter, despite a 43% increase in the African population living in malaria transmission areas.

The BBC's David Shukman looks at how this "staggering rate" of success against malaria has been achieved.
