Intensive global efforts to tackle malaria has prevented nearly 700 million cases of the deadly disease in Africa since 2000, a new study shows. A combination of bed nets, new treatments and insecticides distributed by a variety of health organizations and charities like Unicef has dropped malaria death rates an astonishing 60% since the turn of the century. The report also said that 13 countries that had malaria in 2000 no longer have any cases in 2014 while a further six countries had fewer than ten cases. Global malaria control is one of the great public health success stories of the past 15 years.
