7 March 2017 -- This year’s global theme for World Malaria Day is End Malaria for Good. In the lead-up to 25 April, WHO is shining a spotlight on prevention, a critical strategy for reducing the toll of a disease that continues to kill more than 400 000 people annually. Since 2000, malaria prevention has played an important role in reducing cases and deaths, primarily through the scale up of insecticide-treated nets and indoor spraying with insecticides.
