Even though effective way to overcome the malaria has been discovered, in fact these cases is still growing among developed country and murdering 1 million people annually; 90% of them are children from Africa. There exist clinical, laboratorial, and molecular method in diagnosing malaria, however the whole process mostly committed conventionally using microscope and expertise.
