Abstract:
Malaria is widespread in many tropical and
subtropical regions and it kills more people than any
other communicable disease except for tuberculosis.
According to the World Health Organization, 300-500
million people become infected and close to a million
die of malaria each year, mostly children under 5 years
of age. About 40% of the world?s population is at risk
of contracting malaria, particularly in the poorest
1
countries. It is believed that malaria originated in
West and Central Africa and spread all across the
globe to become the worst killer disease.
