10 facts on malaria
About 3.4 billion people – half of the world's population – are at risk of malaria. In 2012, there were about 207 million malaria cases (with an uncertainty range of 135 million to 287 million) and an estimated 627 000 malaria deaths (with an uncertainty range of 473 000 to 789 000). Increased prevention and control measures have led to a reduction in malaria mortality rates by 42% globally since 2000 and by 49% in the WHO African Region.
People living in the poorest countries are the most vulnerable to malaria. In 2012, 90% of all malaria deaths occurred in the WHO African Region, mostly among children under 5 years of age.
