The World Health Organization estimates that half the world's population are at risk of malaria, with 243 million people developing clinical malaria last year (86% in Africa), with nearly 863,000 deaths (89% in Africa, most being children). Malaria remains endemic in 108 countries, and while parasitebased diagnosis is increasing, most suspected cases of malaria are still not properly identified, resulting in over-use of anti-malarial drugs and poor disease monitoring. |
