Number of malaria cases
Estimated cases, 2012
There were an estimated 207 million cases of malaria worldwide in 2012 (uncertainty interval, 135–287 million).
Most of the estimated cases (80%) occur in sub-Saharan Africa. About 9% of estimated cases globally are due to P. vivax, although the proportion outside the African continent is 50%. The estimated incidence of malaria fell by 25% globally between 2000 and 2012, and by 31% in the African Region.
Note: updated country estimates (2014) will be available by end 2015.
