Malaria is caused by a parasite spread through the bite of infected mosquitoes. The World Health Organization, in its latest estimate, says the disease caused seven hundred eighty-one thousand deaths in two thousand nine. Most of those deaths were in children in Africa. Worldwide there were two hundred twenty-five million cases of malaria.
