Malaria is a mosquito-borne infectious disease affecting humans and other animals caused by parasitic protozoans (a group of single-celled microorganisms) belonging to the Plasmodium type.
Over the past 15 years, there has been a dramatic decline in the global burden of malaria. Since 2000, nearly 60 countries have reduced their malaria cases by 75% or more, and the rate of new cases has decreased by 37% globally. But our journey is far from over. In 2015 alone, more than 400 000 people died of malaria, and there were 214 million new cases of the disease.
