World Malaria Day 2018 is commemorated every on 25 April. It recognizes global efforts to control malaria. Globally, 3.3 billion people in 106 countries are at risk of malaria. In 2009, 781 000 people died from malaria, mainly women and children in Africa
World Malaria Day was established in May 2007 by the 60th session of the World Health Assembly, the decision-making body of the World Health Organization. The day was established to provide "education and understanding of malaria" and spread information on "year-long intensified implementation of national malaria-control strategies, including community-based activities for malaria prevention and treatment in endemic areas."
Malaria is a mosquito-borne infectious disease of humans. It is widespread in tropical and subtropical regions, including much of Sub-Saharan Africa, Asia and the Americas. The disease results from the multiplication of malaria parasites within red blood cells, causing symptoms that typically include fever and headache, in severe cases progressing to coma, and death.
Malaria is not just a disease commonly associated with poverty but also a cause of poverty and a major hindrance to economic development. Tropical regions are affected most, however malaria's furthest extent reaches into some temperate zones with extreme seasonal changes. The disease has been associated with major negative economic effects on regions where it is widespread. During the late 19th and early 20th centuries, it was a major factor in the slow economic development of the American southern states. (With material from Wikipedia)
