Malaria transmission occurs in five WHO regions. Globally, an estimated 3.4 billion people in 91 countries and territories are at risk of being infected with malaria and developing disease (map), and 1.1 billion are at high risk (>1 in 1000 chance of getting malaria in a year). According to the World Malaria Report 2016, there were 212 million cases of malaria globally in 2015 (uncertainty range 148–304 million) and 429 000 malaria deaths (range 235 000–639 000), representing a decrease in malaria cases and deaths of 22% and 50% since 2000, respectively. The burden was heaviest in the WHO African Region, where an estimated 92% of all malaria deaths occurred, and in children aged under 5 years, who accounted for more than two thirds of all deaths.
