The World Heath Organization released a report on the state of malaria prevention efforts. Sixteen countries reported zero cases of malaria in 2014 and seventeen reported fewer than 1000 cases. Much progress has been made in the Europe, The Americas, Southeast Asia and the Western Pacific. Sub-Saharan Africa remains the hot spot for malaria with 88% of the cases and 90% of the mortality. Globally, the number of malaria cases fell from a range of 205–316 million in 2000 to a range of 149–303 million in 2014. Most of the uncertainty and variability are due to insufficient medical care facilities in Africa.
Malaria reduction is due to an insecticide bed net program that now has over half the population of Sub-Saharan Africa sleeping under bed nets that prevent mosquito bites at night, a program of treating walls with mosquito repelling insecticides and better drug treatments that reduce the transmission of malaria from infected humans. A new goal was set to reduce incidence and mortality from malaria by 90% by 2030. This goal can potentially be achieved without an effective vaccine. The development of an effective vaccine could produce even more and more rapid progress.
