Doctor Andrew Nash holds a quick-detect malaria kit September 2, developed by Australian drug research company AMRAD Corporation. The test can detect two different strains of malaria from a finger prick blood sample. The World Health Organisation cites malaria as one of the world's most serious health problems. The disease, carried by some mosquitoes, effects 100 countries with about 40 percent of the world's population exposed. It is estimated that 300 million people are infected with malaria which kills one to 1.5 million a year.
