25 April - World Malaria Day
Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected mosquitoes.
Symptoms of malaria include fever, shivering, arthralgia (joint pain), vomiting, anemia (caused by hemolysis), jaundice, hemoglobinuria, retinal damage, and convulsions.
There were an estimated 225 million cases of malaria worldwide in 2009. An estimated 655,000 people died from malaria in 2010, a decrease from the 781,000 who died in 2009 according to the World Health Organization's 2011 World Malaria Report, accounting for 2.23% of deaths worldwide. However, a 2012 meta-study from the University of Washington and University of Queensland estimates that malaria deaths are significantly higher. Published in The Lancet, the study estimates that 1,238,000 people died from malaria in 2010.
