WHO noted World Malaria Day – 25 April 2011, stating that “approximately half of the world’s population is at risk of malaria, particularly those living in lower-income countries. It infects more than 500 million people per year and kills more than 1 million. The burden of malaria is heaviest in sub-Saharan Africa but the disease also afflicts Asia, Latin America, the Middle East and even parts of Europe.” http://www.who.int/mediacentre/events/annual/malaria/en/index.html
