Malaria Atlas Project used national reports, ecological and epidemological models to create a new global map of P. falciparum malaria risk. Guerra et al 2008 PLoS Medicine estimate that 2.37 billion people live in areas at risk of P. falciparum transmission. However, almost a billion people of those people live in areas with only episodic or very low risk of malaria exposuire suggesting there in substantial possibility of eliminating malaria from these areas. Almost all areas with high risk are in Africa.
Below is a small version of their global map of P. Falciparium (the most dangerous species) of Malaria risk for 2007:
Their maps can be viewed in google earth, as country maps, or as as an ArcGrid file at 0.1 degree spatial resolution.
