New drug-resistant strains of malaria could thwart global efforts to halve malaria deaths by 2010 unless major players in the fight against the disease speed up the rollout of vital new drugs, health experts say. Ninety percent of all malaria deaths are in Africa, where experts say the emergence of drug-resistant strains help maintain a staggering death rate, particularly among children. An African child dies from malaria every 30 seconds.
